Best Lift Kit For Travel Trailer: Compare Axle Fits and Lift Heights

#1 · Best Overall

1. RecPro Single Axle Torflex Kit

Best for: Single-axle #10 Torflex owners.

Why it ranks #1: Specifies a #10 Torflex fit for 2,300–4,000-pound axles, a 3-inch frame lift, and included spacers and mounting hardware.

A 3-inch frame lift is the defining feature of RecPro’s single-axle Torflex kit, giving compatible trailers extra clearance to help avoid axle clearance issues. Its specified #10 axle range is 2,300 to 4,000 pounds, making capacity and axle type the key checks before choosing it.

The kit pairs two #10 frame spacers with eight hex screws, eight washers, and eight locking hex nuts, so the listed mounting hardware is included for installation. Spacers use an 8-inch center-to-center bolt-hole distance, a practical measurement to compare with the trailer frame before work begins. The 3-inch lift raises the frame for added clearance, while the stated 2,300–4,000-pound capacity range limits its fit to compatible #10 Torflex setups.

Skip it if you have a 4,400-pound Lippert torsion axle on an RPOD; the Generic 3-1/2-inch RPOD riser is specified for that application.

Choose this kit if your single-axle trailer uses a #10 Torflex axle within the listed capacity range and needs a 3-inch frame lift. Check the 8-inch spacer hole spacing against your frame before installation.

#2 · Broad Torflex Fit

2. Cindervane Torflex Lift Kit

Best for: Side-mounted single-axle torsion setups.

Why it ranks #2: Lists #9, #10, #11, and #12 axle compatibility and a 3-inch lift, though its stated capacity range is 2,300–4,000 pounds.

A 3-inch lift paired with compatibility across #9, #10, #11, and #12 axle labels distinguishes this Cindervane kit. It is listed for single-axle torsion trailers rated 2,300 to 4,000 pounds, helping owners seeking added ground clearance on uneven roads identify a potentially suitable application.

The lift spacers and included bolts, washers, and locking nuts supply the stated mounting hardware for installation. Its side-mounted axle-bracket application narrows where it fits, while the 2,300–4,000-pound rating range and single-axle requirement help screen out incompatible setups. The approximately 3-inch rise adds ground clearance, a useful change for uneven-road travel, but the axle label alone does not replace checking the trailer’s bracket arrangement.

Skip it if you need a lift for a 4,400-pound RPOD Lippert torsion axle; the Generic RPOD 3-1/2-inch riser is specified for that setup.

This suits owners of single-axle torsion trailers in the listed capacity range whose brackets are side-mounted and who want about 3 inches of added clearance. The bracket position remains a key fit consideration.

#3 · Higher Capacity

3. Dexter K71-385-00 Kit

Best for: 5,200–7,000-pound round-tube axles.

Why it ranks #3: Fits 5,200–7,000-pound axles with 3-inch tubes and 2-inch leaf springs, and provides a stated 3–4-inch lift.

Dexter’s over/under conversion lifts a trailer by 3 to 4 inches and targets 5,200–7,000-pound axles. Its fit is further defined by a 3-inch axle tube and 2-inch-wide leaf springs, making it a specific option for owners considering a spring-and-axle arrangement change.

The kit’s four U-bolts, two tie plates, two seats, four spacers, and eight nuts provide the listed components for one axle. The over/under conversion changes the axle-and-spring relationship, while the 3-to-4-inch lift can add trailer clearance. Compatibility is limited to 3-inch round-tube axles and 2-inch-wide leaf springs within the stated 5,200–7,000-pound range, so those dimensions matter before installation.

Skip it if you have a 3,500-pound axle with a 2-3/8-inch tube; the Dexter K71-384-00 is listed for that size.

This is for owners making an over/under conversion on one axle with the specified 3-inch tube, 2-inch leaf springs, and 5,200–7,000-pound rating. Check all three dimensions before choosing the kit.

#4 · 3500-Pound Axles

4. Dexter K71-384-00 Kit

Best for: 3,500-pound axle conversion buyers.

Why it ranks #4: Targets 3,500-pound axles with 2-3/8-inch tubes and 1-3/4-inch leaf springs; the listed lift is 3–4 inches.

A 3-to-4-inch lift for 3,500-pound axles defines Dexter’s K71-384-00 over/under conversion kit. It is specified for a 2-3/8-inch axle tube and 1-3/4-inch-wide leaf springs, giving owners of that narrower configuration a clear way to assess whether this conversion fits.

The included four U-bolts, two tie plates, two seats, four spacers, and eight nuts provide the listed parts for one axle. The over/under conversion raises the trailer by 3 to 4 inches, adding clearance while changing the axle-and-spring arrangement. Its 3,500-pound rating, 2-3/8-inch tube, and 1-3/4-inch spring width are essential fit limits; this is not the 3-inch-tube configuration.

Skip it if you have a 5,200–7,000-pound axle with a 3-inch tube and 2-inch leaf springs; Dexter K71-385-00 specifies that configuration.

Choose this conversion kit when a 3,500-pound trailer axle uses the listed 2-3/8-inch tube and 1-3/4-inch leaf springs. Its 3-to-4-inch lift applies to that specific configuration, so confirm those dimensions.

#5 · RPOD-Specific Fit

5. RPOD 3-1/2-Inch Riser Kit

Best for: RPOD owners with 4,400-pound axles.

Why it ranks #5: Designed for RPOD trailers with 4,400-pound LCI Lippert torsion axles and supplies a 3-1/2-inch rise with mounting hardware.

A 3-1/2-inch riser specified for RPOD campers with a 4,400-pound LCI Lippert torsion axle is this kit’s defining match. The added height is intended to increase ground clearance over rough or uneven terrain, while the stated axle and trailer application keep its fit notably specific.

The riser’s stated 3-1/2-inch lift raises an RPOD trailer for added clearance on uneven surfaces. Its specified 4,400-pound LCI Lippert torsion axle application gives owners a concrete compatibility point to check, rather than relying on lift height alone. Powder-coated steel construction and included mounting hardware support the installation package, and instructions are listed as included. Confirm the trailer and axle match the stated application before selecting this riser.

Skip it if you have a 2,300–4,000-pound single-axle Torflex setup; the Cindervane K71-707-01 lists that capacity range.

A useful match for an RPOD owner seeking extra clearance on rough terrain, provided the trailer has the specified 4,400-pound LCI Lippert torsion axle. Its focused application makes axle verification essential before purchase.

6. RPOD 4400-Pound Riser Kit

Best for: RPOD Lippert axle replacement buyers.

Why it ranks #6: Describes a 3-1/2-inch lift for Lippert 4,400-pound torsion axles and gives 9-inch center-to-center mounting-hole spacing.

A 3-1/2-inch riser with two axle risers is the concrete offering in this RPOD camper replacement kit. Its description specifies Lippert 4,400-pound torsion axle applications and 9-inch center-to-center mounting-hole spacing, giving owners two useful points to check against their trailer.

The stated 3-1/2-inch lift adds clearance, while the 9-inch center-to-center mounting-hole spacing provides a practical measurement for checking the installation layout. The description identifies the application as an RPOD camper with a Lippert 4,400-pound torsion axle and says the package includes two #164882 axle risers. Because other component and installation details are not specified, the listed axle application and hole spacing should guide fit decisions.

Skip it if you need a lift kit with listed installation instructions and mounting hardware; the Generic RPOD 3-1/2-inch riser explicitly includes both.

Consider this replacement option for an RPOD camper using a Lippert 4,400-pound torsion axle when its 3-1/2-inch rise and 9-inch hole spacing match your setup. The supplied details are application-specific.

#7

7. Trailer #9 Lift Kit

Best for: #9 Torflex lift applications.

Why it ranks #7: Its title identifies a #9 Torflex application and a 2-5/8-inch lift, but the supplied data gives no axle capacity or fit details.

The title’s 2-5/8-inch lift and #9 Torflex designation make this kit’s intended application easy to identify. It is labeled K71-723-01, giving owners of a #9 Torflex axle a specific model reference when evaluating a lift for trailer clearance.

The listing identifies this as a trailer #9 lift kit for Torflex and states a 2-5/8-inch lift, which gives buyers two central fit details to compare with their existing axle. Its model number is K71-723-01. Beyond those title and specification details, the supplied description does not explain mounting hardware or installation steps, so buyers should not infer a broader axle range or a complete hardware package from the available information.

Skip it if you need a stated 3-1/2-inch lift for a 4,400-pound RPOD Lippert axle; the Generic RPOD riser lists that application.

Consider this for a trailer owner whose axle is the listed #9 Torflex type and who wants the stated 2-5/8-inch lift. The supplied information is sparse, so installation and hardware details remain a boundary.

#8

8. #11 Tandem Torsion Lift Kit

Best for: Tandem torsion axle lift shoppers.

Why it ranks #8: The title describes a #11, 5,200-pound tandem torsion application with a 2-7/8-inch lift, but details are limited.

A stated 2-7/8-inch lift and #11, 5,200-pound tandem torsion axle designation are the clearest identifying details for this kit. Those specifications point toward owners evaluating a tandem torsion setup, though the supplied information gives limited installation detail beyond the included kit identification.

The title identifies a #11 kit for a 5,200-pound tandem torsion axle and states a 2-7/8-inch lift, giving buyers core application and height details to compare with their trailer. The included-components listing names the K71-724-02 lift kit. The additional description discusses a brake-pump actuator rather than explaining lift installation, so it does not add useful mounting guidance; verify that the title’s axle configuration matches your trailer.

Skip it if you need a specified 2-5/8-inch #9 Torflex lift; the Generic K71-723-01 listing names that configuration.

This may suit owners assessing a #11, 5,200-pound tandem torsion setup seeking the stated 2-7/8-inch lift. The listing provides little installation information, so its limited mounting detail is an important boundary.

#9

9. Dexter K71-707-01 Kit

Best for: Double-eye spring hanger setups.

Why it ranks #9: Despite its Torflex Lift Kit title, its details describe a hanger kit for double-eye springs rather than a clear axle-lift application.

This Dexter kit is identified as a single-axle hanger kit for double-eye springs, rather than by a stated lift height. It includes a bushing and the parts described for attaching trailer springs to the frame, making it relevant to owners addressing that specific spring-hanger connection.

The stated purpose is attaching trailer springs to the frame, and the double-eye spring designation narrows the application. A supplied bushing is part of the kit, while the compact listed package dimensions—11.44 by 5.63 by 3.25 inches—give a storage reference. The title calls it a Torflex lift kit, but the feature description specifies a spring hanger kit; buyers should base fit decisions on their spring setup and the stated attachment function.

Skip it if you need a stated lift height for a torsion axle; the Generic K71-723-01 listing specifies a 2-5/8-inch #9 Torflex lift.

This suits owners seeking a single-axle hanger kit for double-eye springs and a frame attachment that includes a bushing. It does not state a lift height, so it is not a height-specific choice.
