A strong choice for a four-post lift is a compatible rolling bridge jack with enough capacity for the vehicle and pad height suited to its clearance. The KATOOL RJ-50W is the leading option here for buyers with a compatible KT-4H110 or 4H850 lift: it is rated for 5,000 pounds and offers three locking height positions. This roundup also compares 3,500-pound bridge jacks, a horizontal replacement tray, and complete four-post lifts that include jack trays.
Those products serve different needs, so a listed capacity or included tray does not automatically mean a part fits your existing lift. Check runway spacing, jack width, mounting or rolling arrangement, and vehicle lifting requirements before ordering.
The details below distinguish standalone jacks from lift packages and identify where compatibility is limited or unspecified.
The KATOOL RJ-50W is the best overall choice among these products for a buyer whose four-post lift is a compatible KT-4H110 or 4H850. Its 5,000-pound capacity, 5.3-inch lowered pad height, 18.3-inch maximum pad height with adapters, and three locking positions support wheel and brake service. It is not presented as universally compatible, so confirm your lift model before buying.
For other setups, compare the Atlas adjustable-width jack or the model-specific Triumph SJ35.

Detailed Reviews: Best Jack Tray For 4 Post Lift

#1 · Best Overall
1. KATOOL RJ-50W
- Load Capacity: 5000 lb
- Dimensions: 25 x 41 x 15 in
- Compatible with Vehicle Type: Car
Best for: Low-clearance wheel-service jack.
Why it ranks #1: Rated for 5,000 pounds, it has three locking positions and 5.3-inch lowered pads; listed compatibility is specifically KT-4H110 and 4H850.
A 5.3-inch lowered pad height lets the KATOOL rolling bridge jack slide beneath vehicles on a compatible four-post lift, while adapters extend its maximum pad height to 18.3 inches. Its 5,000-pound capacity and three locking positions support wheel and brake work without moving the vehicle off the lift.
The hydraulic hand pump raises the jack, and its four pulleys let it roll along the lift for front- or rear-wheel access. Two large rubber pads provide vehicle contact, while three locking height positions give operators set stopping points during lifting. The 5,000-pound capacity suits many car-service tasks, and the low lowered height aids access beneath vehicles. The listing specifically identifies KT-4H110 and 4H850 lifts, so compatibility beyond those models is not established here.
- 5.3-inch lowered pad height
- 18.3-inch maximum pad height with adapters
- 5,000-pound capacity with three locking positions
- Hydraulic hand pump and four rolling pulleys
- Listed compatibility is limited to KT-4H110 and 4H850 lifts.
Skip it if you need a jack explicitly listed for another lift; the ATLAS XH-PROJACK35 instead names Atlas Garage Pro 8000 and 9000 compatibility.
Choose this KATOOL for wheel or brake service on a KT-4H110 or 4H850 four-post lift, especially when low pad clearance matters. Its 5,000-pound rating and listed compatibility should guide the fit decision.

2. Atlas XH-PROJACK35
- Load Capacity: 3500 lb
- Dimensions: 23 x 37 x 10 in
- Compatible with Vehicle Type: Truck
- Material: Alloy Steel
Best for: Adjustable-width truck-service jack.
Why it ranks #2: Its 3,500-pound capacity, adjustable width for many four-post lifts, and included four-piece truck adapter set suit varied compatible setups.
Adjustable width lets the ATLAS XH-PROJACK35 fit many four-post lifts, making it a flexible sliding bridge jack for wheel service. Its 3,500-pound capacity, manual hand pump, and included four-piece truck adapter set equip the jack for lifting work without requiring a powered pump.
The hand-operated hydraulic pump gives the operator manual control over lifting, while a scissor mechanism raises the vehicle level. Adjustable width helps the jack accommodate many four-post lift layouts, and the included four-piece truck adapter set adds contact options for truck applications. Its 3,500-pound capacity defines the load limit. The listing specifically names Atlas Garage Pro 8000 and 9000 compatibility for the RJ-35, but does not establish fit for every four-post lift.
- 3,500-pound capacity
- Manual hand-pump operation
- Scissor mechanism for level lifting
- Adjustable width and four-piece truck adapter set
- The 3,500-pound capacity is below the 5,000-pound rating of the KATOOL RJ-50W.
Skip it if you need more than 3,500 pounds of capacity; the KATOOL RJ-50W is rated for 5,000 pounds on its listed compatible lifts.
Choose the ATLAS for truck wheel service when adjustable width, manual operation, and included adapters match your setup. Its 3,500-pound capacity and named Atlas Garage Pro compatibility should factor into the vehicle and lift fit.

3. Triumph SJ35
- Load Capacity: 3500 lb
- Dimensions: 24 x 39 x 16.5 in
- Compatible with Vehicle Type: Car
- Material: Alloy Steel
Best for: Triumph-lift bridge jack.
Why it ranks #3: This 3,500-pound bridge jack has three locking positions and a 4.75-inch lowered pad height, with listed fit for several Triumph lifts.
A 4.75-inch lowered pad height helps the TRIUMPH SJ35 reach beneath vehicles, while adapters extend its maximum pad height to 16.5 inches. This 3,500-pound bridge jack uses a manual hydraulic pump and three locking height positions for wheel-service lifting on a compatible four-post setup.
The manual hydraulic pump raises the jack without a powered motor, and three locking positions provide defined raised settings. Its 4.75-inch lowered height and 16.5-inch maximum height with adapters describe the working range for vehicle access and lift. The jack requires approximately 38 inches between runways. Compatibility is identified for current Triumph 8,000-pound four-post parking storage lifts, NSS8SQ Classic, NSS8, and NSS8XLT; fit with other brands is not guaranteed.
- 3,500-pound capacity
- 4.75-inch lowered pad height
- 16.5-inch maximum pad height with adapters
- Manual hydraulic pump and three locking positions
- Requires approximately 38 inches between runways.
Skip it if you need a jack with explicitly listed non-Triumph lift compatibility; the KATOOL RJ-50W names KT-4H110 and 4H850 models.
The SJ35 suits owners of listed Triumph four-post storage lifts who need manual bridge-jack support for wheel service. Check the approximately 38-inch runway spacing and listed model compatibility before selecting it.

View on AmazonWhy it ranks #4: This complete 9,500-pound four-post lift lists a jack tray among its included features, but it is a lift package rather than a standalone jack.
An extra-wide 113-inch layout gives the KATRAX KT-4H950 room for full-size trucks and SUVs, with a listed 9,500-pound capacity. The four-post lift also includes a jack tray, ramp, drip tray, and casters, bringing storage and service equipment together in one setup.
The 9,500-pound capacity and extra-wide 113-inch design are specified for large vehicles, including full-size trucks and SUVs. A maximum lifting height listed as 81 inches in the features provides the stated clearance for raised-vehicle work. Four posts have primary and secondary mechanical locks, with a single-point manual release. The 3.0 HP, 110V/60Hz motor identifies its power specification; verified information calls for direct connection to a power source rather than relying on a wall socket.

Skip it if you need a standalone bridge jack instead of a complete lift; the KATOOL RJ-50W is a 5,000-pound rolling jack for specified four-post models.
This KATRAX is suited to spacious garages or shops storing and servicing wide trucks and SUVs. Its 113-inch design and 9,500-pound capacity are key fit points; account for its direct-power requirement when planning installation.

5. KATOOL 4-H95 Lift
- Load Capacity: 9500 lb
- Dimensions: 186 x 30 x 23 in
- Compatible with Vehicle Type: Universal Fit
- Material: Alloy Steel
Best for: Home-garage storage lift.
Why it ranks #5: The 9,500-pound lift listing includes a jack tray and caster moving kit; it is relevant as a full lift package, not as a replacement jack.
An 84-inch maximum lifting height gives the KATOOL 4-H95 four-post lift substantial clearance for vehicle storage and service. Its 9,500-pound capacity and included oil tray, jack tray, aluminum ramp, and moving casters make it a full lift package rather than a standalone jack tray.
The 9,500-pound capacity supports the lift’s stated vehicle-use range, while the 84-inch maximum height defines clearance beneath a raised vehicle. Aluminum ramps provide the drive-on route, and the included oil tray and jack tray add service-oriented equipment. Casters are listed for moving the lift, supporting repositioning when needed. The lift uses a 3.0 HP, 110V setup, but the supplied verified information says it should connect directly to a power source rather than rely on a wall socket.
- 9,500-pound capacity
- 84-inch maximum lifting height
- Oil tray, jack tray, aluminum ramp, and casters included
- 3.0 HP, 110V power specification
- Requires direct connection to a power source rather than a wall socket.
Skip it if you need a bridge jack alone; the TRIUMPH SJ35 is a separate 3,500-pound jack with a manual hydraulic pump.
Pick this KATOOL for a garage or service space needing a complete four-post lift with an included jack tray, ramp, and casters. The 84-inch height and direct-power requirement are important installation considerations.

Why it ranks #6: This 9,500-pound four-post lift listing includes a jack tray, ramps, and drip trays, but does not serve as a standalone bridge jack.
A 9,500-pound capacity paired with a 79-inch maximum lifting height gives the Motool KT-4H950 room for heavy vehicle storage, maintenance, and detailing. The four-post lift includes ramps, casters, and drip trays, combining vehicle elevation with practical supporting equipment for shop or garage use.
Four mechanical locks, arranged as primary and secondary safety devices, secure the lift at its raised position; a single-point manual release simplifies unlocking. Its 110V, 60Hz, 3.0 HP power specification identifies the electrical setup, while the 79-inch maximum height sets the available clearance for work beneath a raised vehicle. Included casters support transport, and ramps and drip trays come with the lift. Buyers must arrange forklift or tractor unloading.

7. Yuudar Horizontal Jack Tray
- Load Capacity: 8E+3 lb
- Dimensions: 4.5 x 4.5 x 0.5 in
- Compatible with Vehicle Type: Car, Light Truck, Sport Utility Vehicle
- Material: Alloy Steel, Rubber
Best for: Replacement tray for 3–4 ton jacks.
Why it ranks #7: It is a replacement-style tray for 3–4-ton applications with mounting hardware, but the listing does not establish compatibility with four-post lifts.
A horizontal support surface gives the Yuudar jack tray a role in 3- to 4-ton jack applications, supporting vehicle maintenance and towing tasks. Its alloy-steel and rubber construction combines a firm structural material with a contact surface, and mounting hardware is included for fitting the tray to a compatible setup.
The horizontal design provides a stable positioning surface during car repairs or towing, according to the listing. Alloy steel supplies the tray’s structural material, while rubber is also listed in its construction; together, these materials make it a distinct replacement accessory rather than a complete lifting jack. Mounting hardware comes in the package, but the supplied details do not identify specific jack models or explain a particular attachment method. Check the stated 3- to 4-ton application against your jack.
- Horizontal support design
- For 3- to 4-ton capacity applications
- Alloy steel and rubber construction
- Mounting hardware included
- Specific compatible jack models are not identified in the supplied listing.
Skip it if you need a complete bridge jack; the ATLAS XH-PROJACK35 includes a manual pump, adjustable width, and truck adapters.
Consider the Yuudar when replacing or adding a horizontal tray for a 3- to 4-ton jack used in car repair or towing. Its listing does not name compatible jack models, so verify the application from the provided specifications.

View on AmazonAvoid the bridge-jack fit trap
A jack that carries the right load can still fail to fit your lift, so verify the lift model and runway spacing before ordering. The KATOOL RJ-50W is listed for KT-4H110 and 4H850 lifts, while the Triumph SJ35 is listed for several Triumph models and requires approximately 38 inches between runways. Its manufacturer does not guarantee fit with other brands.
The Atlas XH-PROJACK35 instead states that its width adjusts to fit many four-post lifts, but that wording is not a guarantee for every model. Measure the usable space between runways and compare the jack’s dimensions or adjustment range with the lift manufacturer’s requirements.
Treat a seller’s general phrase such as “universal” cautiously when the listing also names specific compatible models. If the product data does not confirm your exact fit, ask the lift manufacturer or seller before relying on it.
A tray is not the same as a bridge jack
A replacement tray and a complete rolling bridge jack are different purchases, even when both listings use the words jack tray. The Yuudar item is described as a horizontal tray for 3–4-ton applications and includes mounting hardware, but the listing does not specify a four-post lift fit or provide pad-height and locking details. By contrast, the KATOOL RJ-50W, Atlas XH-PROJACK35, and Triumph SJ35 are bridge jacks with stated lifting capacities; the KATOOL and Triumph listings also specify multiple locking positions.
The KATRAX, KATOOL 4-H95, and Motool products are entire four-post lift packages that list a jack tray among their features. That may suit a buyer choosing a complete lift, but it does not establish that the included tray or jack fits an existing lift.
Match the purchase type to the missing component, and verify what is actually included before ordering.
How to Choose a Four-Post Lift Jack
Capacity and lifting use
Look for a stated jack capacity that suits the vehicle and the portion of it being lifted. The standalone bridge jacks in this set are rated at 3,500 pounds for the Atlas XH-PROJACK35 and Triumph SJ35, and 5,000 pounds for the KATOOL RJ-50W. Do not treat the 9,500-pound ratings on the KATRAX, KATOOL 4-H95, and Motool listings as jack capacities: those are complete lift packages.
A buyer with a compatible lift and a need for more listed jack capacity should consider the KATOOL RJ-50W. The two 3,500-pound models may suit buyers whose requirements fit that rating and who confirm compatibility.
Use your vehicle and lift documentation to determine suitable capacity rather than assuming the vehicle’s total weight is the only consideration.
Pad height and locking positions
Check lowered pad height, maximum reach, and locking options against the vehicle’s clearance and lifting points. The KATOOL RJ-50W lists a 5.3-inch lowered pad height and reaches 18.3 inches with adapters, with three locking positions. The Triumph SJ35 starts lower at 4.75 inches and reaches 16.5 inches with adapters, also with three locking positions.
The Atlas listing gives its 3,500-pound capacity and included truck adapter set but does not provide pad-height figures in the supplied data. Buyers working with lower-clearance vehicles may prefer the lower stated pad height of the Triumph, if it fits their lift; buyers needing the higher stated reach may favor the KATOOL.
Confirm adapter and vehicle contact requirements before use.
Lift compatibility and package type
Confirm whether you need a standalone bridge jack, a replacement tray, or an entire four-post lift, then verify compatibility with your lift model. The KATOOL RJ-50W names KT-4H110 and 4H850 compatibility; the Triumph SJ35 lists specific Triumph models and approximately 38 inches of runway spacing. Atlas says the XH-PROJACK35 has adjustable width to fit many four-post lifts, without naming every supported model.
The Yuudar product is a tray for 3–4-ton applications, not a documented four-post bridge jack. The three 9,500-pound lift packages list jack trays but are complete lifts.
Buyers replacing a jack should prioritize model fit and measurements; buyers shopping for a whole lift should assess those packages separately.
Which Four-Post Lift Jack Should You Choose?
Choose the KATOOL RJ-50W if your lift is a KT-4H110 or 4H850 and its 5,000-pound capacity and pad range suit your vehicle. For a broader stated adjustment option, the Atlas XH-PROJACK35 has adjustable width for many four-post lifts and includes truck adapters; confirm your exact model. The Triumph SJ35 is a 3,500-pound choice for listed Triumph lift models, with a 4.75-inch lowered pad and a stated runway-spacing requirement.
If you need only a tray, the Yuudar Horizontal Jack Tray is the relevant style, but its four-post compatibility is not established. The KATRAX, KATOOL 4-H95, and Motool listings are complete lift packages with trays, not standalone replacement bridge jacks.

Frequently Asked Questions
How do I measure runway spacing and jack width before buying a bridge jack?
Measure the clear distance between the runways where the jack will sit, then compare it with the jack’s stated spacing and width range. Check the exact lift model’s compatibility information, too. The Triumph SJ35 listing specifies a runway-spacing requirement, but no measurement is provided here; confirm that requirement before purchase.
Can a bridge jack lift one end of a vehicle safely if the vehicle is unevenly loaded?
Not automatically. An uneven load can shift the vehicle’s center of gravity, so do not assume a bridge jack can safely lift one end under those conditions. Check the vehicle and lift manuals, observe the jack’s capacity and positioning instructions, and stop if the vehicle cannot be supported in a stable, balanced position.
What maintenance should I perform on a hydraulic bridge jack before use?
Before each use, check for hydraulic leaks, visible damage, loose parts, and smooth operation of the lifting and locking mechanisms. Inspect contact pads and wheels, and make sure the jack is correctly positioned on the runways. Follow the manufacturer’s instructions for hydraulic fluid, servicing, and any maintenance intervals; do not use a faulty jack.
Is a jack tray the same as a bridge jack?
No. A bridge jack is a lifting device that spans the runways; a tray is an accessory or replacement part. The Yuudar listing is for a horizontal jack tray, and its compatibility with four-post lifts is not established here.
Confirm fit with the seller or manufacturer before treating it as a replacement for a bridge jack.
How can I tell whether a listing is a standalone jack or a complete lift package?
Read the title and product description for what is actually included. The KATRAX, KATOOL 4-H95, and Motool listings are complete lift packages with trays, not standalone replacement bridge jacks. If you need a jack for an existing lift, verify that the listing is for the jack itself and confirms compatibility with your lift model.
Final Words
Start with your exact lift model and the job you need to do. For a compatible KT-4H110 or 4H850, the KATOOL RJ-50W is the article’s best overall choice; confirm fit before buying. For other setups, compare the Atlas adjustable-width jack or the Triumph SJ35 for listed Triumph models.
If you need only a tray, consider the Yuudar listing, but verify compatibility. Treat lift packages as complete lifts, not replacement jacks.
