#1 · Best Overall

1. M MATI Honda Rear Axle

• Package Dimensions: 36.2 x 2 x 1.1 in
• Weight: 8.38 lb

Best for: Specified Honda ATV Replacements.

Why it ranks #1: Lists fitment for Honda Rancher 420 and Foreman 500/520 models, with year ranges and exceptions, and includes two nuts and two pins.

Honda model and year fitment is the key distinction of this M MATI rear axle shaft, covering listed Rancher 420 and Foreman 500/520 versions from specified years. That makes it a targeted replacement option for owners identifying their machine by model, trim, and year rather than axle length alone.

The fitment list includes Rancher 420 TRX420 variants from 2014–2024, with stated exclusions, and Foreman 500/520 variants across specified year ranges. Checking those exact model codes and exceptions before ordering is central to choosing this shaft. Its high-strength metal construction is described as resistant to rust and intended for long service life, while the package includes two axle nuts and two pins alongside the shaft for the replacement task.

Skip it if you own a Kawasaki KFX400 or Suzuki LT-Z400; M MATI’s KFX400/LT-Z400 axle lists those applications.

This fits buyers seeking a model-specific shaft for the listed Honda Rancher 420 or Foreman 500/520 configurations. Verify the exact trim and year against its exclusions; Rubicon editions and specified IRS Rancher variants are not covered.

#2 · Best Model-Specific Fit

2. M MATI Suzuki Kawasaki Axle

• Package Dimensions: 37.8 x 6.1 x 5.51 in
• Weight: 17.31 lb

Best for: KFX400 And LT-Z400 Owners.

Why it ranks #2: Names Suzuki LT-Z400 and Kawasaki KFX400 fitment, including model years, and supplies the shaft, two nuts, and two pins.

Listed Kawasaki KFX400 and Suzuki LT-Z400 fitment makes this M MATI shaft a focused replacement for owners of those specified machines. Rather than a universal kart axle, it identifies particular model years and includes nuts and pins, helping frame the purchase around a defined rear-wheel application.

The fitment information covers Kawasaki KFX400 models from 2003–2006 and Suzuki QuadSport 400 LT-Z400 versions from 2003–2008, with the 2003–2007 range limited to K5/K6/K7 models. Those details make model-year checking essential before installation. M MATI specifies premium steel with high strength and wear and corrosion resistance, which supports use as a replacement rear axle. The package also includes two nuts and two pins for the installation process.

Skip it if you need an axle for a Honda Rancher; M MATI’s Rancher 420 axle lists compatible Honda variants.

This is a targeted choice for owners of the listed KFX400 or LT-Z400 models needing a rear-wheel axle shaft. Confirm Suzuki submodel details, particularly for 2003–2007 machines, where the listing specifies K5/K6/K7 only.

#3 · Best Complete Kit

3. GXYWADY 32-Inch Axle Kit

• Weight: 17.31 lb

Best for: Complete 32-Inch Kart Kits.

Why it ranks #3: An 815 mm live axle kit for ATV and go-kart builds, with brake assembly and pillow blocks; the listing states a capacity above 500 pounds.

A 32-inch live axle kit that includes pillow blocks and a brake assembly gives this GXYWADY package a broad scope for go-kart, ATV, quad, or drift-trike rebuilds. Its 815mm length and stated 30mm thickest section give builders concrete dimensions to compare against their existing setup.

The included pair of pillow blocks and brake assembly can simplify sourcing for a rebuild, while the 815mm axle length helps establish whether the shaft suits the chassis layout. GXYWADY specifies a 190mm brake disc and 24T and 28T spline teeth, details that matter when matching components. The listing says the axle can support more than 500lbs and identifies high-strength chrome, but buyers still need to check their own wheel and mounting arrangement.

Skip it if you need a 40-inch shaft; XIKOBY’s 40 Inch Go Kart Axle Kit lists that longer axle length.

This suits DIY builders seeking a 32-inch axle package with pillow blocks and braking components for a go-kart, ATV, quad, or drift trike. Check spline and mounting compatibility before installation; the listed dimensions define the fit.

#4 · Best Brake Details

4. ANTUKO 32-Inch Axle Kit

• Weight: 19.62 lb

Best for: 32-Inch Axle With Brake Cylinder.

Why it ranks #4: Lists a 190 mm brake disc, 428-chain sprocket with 37 teeth, and 23- and 28-tooth splines for buyers matching a custom setup.

A 32-inch (815mm) axle kit listing a brake master cylinder gives this ANTUKO package a notable braking-system component for go-kart and ATV rebuilds. The specified 190mm brake disc, 428-model sprocket, and 37 teeth also provide useful details for checking a proposed drivetrain and brake setup.

The axle’s 30mm thickest section and 11cm four-hole diagonal hub dimension give builders measurable points for comparing their existing parts. ANTUKO lists 23T and 28T spline counts, alongside a 190mm brake disc and 428-model, 37-tooth sprocket; checking those interfaces can help avoid mismatched components during assembly. The listing calls the kit easy to install but also advises checking hole positions, making measurement important before committing to the replacement.

Skip it if you need a 24-inch axle; RiToEasysports’ Kart Rear Axle Kit lists that shorter size for DIY rebuilds.

This suits a builder whose 32-inch layout matches the listed hub, spline, sprocket, and brake dimensions. Check hole positions and component interfaces before installation; the package’s specified measurements are central to a workable fit.

5. SEBLAFF 32-Inch Assembly

• Package Dimensions: 33.5 x 8 x 3 in
• Weight: 19.55 lb

Best for: Compact 32-Inch Kart Rebuilds.

Why it ranks #5: A complete 815 mm assembly for go-kart and ATV builds; listed details include a 30 mm thickest axle section and hubs, chain, and brake.

An 815mm (32-inch) axle with a 30mm-thick section gives this SEBLAFF assembly a defined size for a go-kart or ATV rebuild. The kit combines the shaft with hub, chain, and brake components, helping buyers source a coordinated assembly rather than an axle shaft alone.

The four-hole diagonal wheel hub measures 11cm, while the sprocket and brake disc are specified at 8mm; those dimensions give builders concrete measurements to compare with their existing setup. The 10mm flanges on both sides and 30mm thickest axle section further clarify the assembly’s dimensions. SEBLAFF identifies it as a modified part and notes that the metal axle can have a normal radian and bend, so measuring before purchase matters when planning installation.

Skip it if you need a vehicle-specific replacement; M MATI’s Rancher 420 axle lists defined Honda model fitment.

This suits a go-kart or ATV builder assembling around an 815mm axle and the listed hub dimensions. Measure the existing setup carefully; SEBLAFF identifies this as a modified part, not a model-specific fitment.

6. SEBLAFF 32-Inch Kit

• Weight: 17.42 lb

Best for: 32-Inch Kart And Drift-Trike Kits.

Why it ranks #6: A 32-inch go-kart, quad, and drift-trike kit that includes a shaft, hub, and brake; the listing calls for measuring before purchase.

This SEBLAFF kit combines a 32-inch axle with a hub and brake, giving go-kart, quad, and drift-trike builders a bundled replacement option. The listed metal axle may have a normal radian and some flex, while the brake disc is described as made from serviceable material.

The 32-inch size establishes the axle length for comparing against a current setup, and the included hub and brake components make the package broader than a shaft-only replacement. SEBLAFF advises measuring before purchase because this is a modified part. Its note that the metal axle may have a normal radian and bend helps set expectations for the shaft, while the company describes the brake disc as serviceable. Careful measurement remains central to installation planning.

Skip it if you need specified Honda model fitment; M MATI’s Rear Axle Shaft & Nuts lists Rancher 420 and Foreman applications.

This suits go-kart, quad, or drift-trike builders whose setup matches a 32-inch axle and the included hub and brake. Measure the current parts carefully; SEBLAFF identifies the assembly as modified and notes normal axle curvature.

#7 · Best Polaris Option

7. SuperATV Rhino 2.0 Axle

• Package Dimensions: 36.5 x 4.6 x 4.55 in
• Weight: 16 lb

Best for: Specified Polaris RZR Applications.

Why it ranks #7: Targets listed Polaris RZR XP 1000 editions and years, but excludes ABS models, so it suits buyers who verify their exact configuration.

The SuperATV Rhino 2.0 rear axle is listed for Polaris RZR XP 1000 High Lifter and Trails and Rocks editions, giving owners of those named models a focused replacement option. Its clearest buying boundary is also explicit: the axle is not compatible with anti-lock brake systems.

The application list covers RZR XP 1000 High Lifter Edition models from 2015–2023 and Trails and Rocks Edition models from 2017–2023. Matching the edition and year to those ranges helps narrow fitment before installation. SuperATV identifies the product as a Rhino 2.0 rear axle, but the supplied facts do not provide dimensions or additional included hardware. The ABS exclusion is important for buyers checking whether this axle suits their braking configuration.

Skip it if you use ABS; M MATI’s listed LT-Z400/KFX400 axle is a different application, so verify your model-specific non-ABS options.

This suits Polaris RZR XP 1000 owners in the listed High Lifter or Trails and Rocks editions and year ranges. Treat ABS compatibility as a firm boundary, and verify the edition before selecting this axle.

#8

8. XIKOBY 40-Inch Axle Kit

• Package Dimensions: 40 x 2.75 x 2.5 in
• Weight: 8.73 lb

Best for: Long-Axle DIY Chassis Builds.

Why it ranks #8: Its 40-inch, 1-inch shaft has a 3/4-inch step-down and 1/4-inch keyway, suiting builds that need those measurements rather than a named ATV fit.

A full 40-inch live axle is the defining feature of this XIKOBY kit, giving longer go-kart, ATV, quad, or dune-buggy builds a specified shaft length to work around. Its 1-inch shaft steps down to 3/4-inch ends, making the end dimensions explicit for assembly planning.

The 1/4-inch keyway slot provides a stated interface for keyed components, while the 3/4-16 fine-thread ends define how the wheel connection is threaded. XIKOBY also lists a 1-inch shaft diameter with step-down ends, helping buyers compare the axle to their bearing and sprocket arrangement before starting work. The 40-inch length supports longer layouts, but this is a shaft-focused kit description; the supplied information does not list a brake assembly or hubs.

Skip it if you need a 32-inch axle with a listed brake assembly; GXYWADY’s 32 Inch Go Kart Rear Axle Kit includes one.

This is for builders whose go-kart, quad, ATV, or dune-buggy layout calls for a 40-inch shaft and matching keyed, threaded connections. Check the component plan separately, since hubs and brakes are not listed in the supplied contents.

#9

9. TJHSM 44-Inch Axle Kit

• Weight: 36.1 lb

Best for: Long 44-Inch Drivetrain Builds.

Why it ranks #9: The 44-inch assembly is the longest listed here and includes a brake assembly; its 33 mm shaft and 530 chain details require careful matching.

A 44-inch rear live axle with a 33mm shaft gives the TJHSM kit its clearest role in longer go-kart, ATV, quad, or drift-trike layouts. Its listed 530 chain and 37-tooth sprocket help buyers evaluate drivetrain matching alongside the substantial axle length.

The 1.12m total length and 33mm shaft diameter provide major dimensions for checking chassis clearance and bearing arrangement. TJHSM specifies a 530 chain with 74 links, a 530 37-tooth sprocket, and a 220mm brake disc, helping buyers compare the drivetrain and braking interfaces before installation. The kit also lists a 90cm brake tube and an 11cm flange diagonal. At 36.1 pounds, the assembly is a substantial item to handle during setup.

Skip it if you need a 32-inch axle; GXYWADY’s 32 Inch Go Kart Rear Axle Kit lists an 815mm shaft with brake assembly.

This suits builders laying out a longer chassis who can match the 44-inch shaft, 530 drivetrain, flange, and brake dimensions. Account for the 36.1-pound assembly during handling, and confirm the listed interfaces suit the vehicle.

#10

10. RiToEasysports 24-Inch Kit

• Package Dimensions: 25.59 x 5.51 x 5.51 in
• Weight: 8.8 lb

Best for: Short 24-Inch DIY Rebuilds.

Why it ranks #10: A short 24-inch DIY axle kit for go-karts, ATVs, quads, and drift trikes, but its listing provides fewer fitment dimensions than the alternatives.

A 24-inch rear axle is the defining measurement of this RiToEasysports kit, making it an option for compact DIY go-kart, ATV, quad, and drift-trike rebuilds. Its listed package includes hubs, fixing mounts, and flanges, so buyers can assess it as an assembly rather than a bare shaft.

The supplied contents identify a rear axle with the flange and holder mounted on the shaft, plus six accessories; the description also names hubs, fixing mounts, and flanges. That combination can reduce separate component sourcing when the dimensions suit the vehicle. The metal construction is described as durable and strong, with the kit intended to support stability and performance. The listing frames fit around size, so comparing the 24-inch length to the existing layout is essential.

Skip it if you need an 815mm axle; ANTUKO’s 32-inch 815mm Go Kart Rear Axle Kit lists that longer size and a brake master cylinder.

This suits DIY builders whose go-kart, ATV, quad, or drift trike calls for a 24-inch axle and the listed assembly components. Measure the existing layout first; the product description makes size the key fit condition.
