Best 6 Inch Leaf Springs for Trucks and Trailers

#1 · Best Overall

1. Rough Country Rear Leaf Springs

• Weight: 130 lb

Best for: GMC rear suspension replacement.

Why it ranks #1: Explicitly listed as a 6-inch rear spring for 1973–1987 GMC C15/K15 trucks, with 2.5-inch width, 555.76 in-lb rate, and included bushings.

An 11.25-inch uncompressed arch distinguishes this Rough Country rear spring, giving buyers a concrete dimension to consider for a six-inch suspension setup. It is listed for 1973–1987 GMC C15/K15 trucks and includes bushings, so the replacement components come together for the specified application.

The 47.875-inch length and 2.5-inch width describe the spring’s size, while its 555.76 lb-in spring rate gives buyers a specific suspension figure to compare with their needs. Rough Country lists alloy-steel construction and a factory-like feel, connecting the replacement to ride comfort as well as suspension support. Bushings are included, and the stated easy bolt-on installation can simplify the replacement workflow; the manufacturer recommends certified technicians for lift-system installation and post-install checks.

Skip it if you need a trailer spring rated at 3,500 pounds per spring; dreamdragon JHLS000006 is listed for that trailer use.

A GMC C15/K15 owner replacing rear springs for a six-inch setup can weigh the listed arch, rate, and included bushings. Keep the stated truck application in view, and use a certified technician for lift-system installation and checks.

#2 · Best Front Spring

2. Rough Country Front Leaf Springs

• Weight: 100 lb

Best for: GMC front spring replacement.

Why it ranks #2: Matches the same 1973–1987 GMC C15/K15 application as a 6-inch front spring; it lists a 733.48 in-lb rate and includes bushings.

A 733.48 lb-in spring rate is the defining specification of this Rough Country front leaf spring, giving GMC truck owners a concrete figure when planning a six-inch suspension replacement. It is listed for 1973–1987 C15/K15 trucks and arrives with bushings for the stated application.

The spring measures 45.75 inches long and 2.5 inches wide, while the 6.875-inch uncompressed arch helps distinguish its front configuration from the brand’s rear spring. Rough Country lists alloy steel and describes a factory-like feel, tying the replacement to ride comfort as well as suspension support. Included bushings and the stated easy bolt-on installation can streamline the job, though Rough Country recommends certified technicians familiar with suspension procedures and post-install checks.

Skip it if you need a spring for a 2009–2014 Ford F-150; Skyjacker FR904S is listed for that truck.

This is for GMC C15/K15 owners selecting a front spring for a six-inch suspension setup, with rate and arch figures to guide comparison. Its listed application is specific; lift-system installation calls for suspension knowledge and post-install checks.

#3 · Best Ford Fit

3. Skyjacker FR904S Softride

• Weight: 88.4 lb

Best for: Ford F-150 Softride replacement.

Why it ranks #3: A specified 6-inch spring for 2009–2014 Ford F-150s, with progressive multileaf construction and load capacity stated as equal to or greater than OE.

Explicitly listed for 2009–2014 Ford F-150 models, the Skyjacker FR904S pairs a six-inch lift spring with progressive multileaf construction. Its stated load capacity is equal to or greater than OE, giving owners of the specified truck a concrete load-support detail to weigh.

The progressive multileaf pack connects the spring’s construction to its stated load-support role, with capacity described as equal to or greater than OE. Skyjacker says it uses American steel and shot-peens each leaf with hard steel pellets, compressing the surface to increase tensile strength. Those details give buyers a clearer view of material and processing, while the explicit 2009–2014 Ford F-150 application narrows the fit decision. This is a six-inch Softride spring, not a general trailer replacement.

Skip it if you are replacing springs on a GMC C15/K15 truck; Rough Country 8015Kit is listed for 1973–1987 models.

Ford F-150 owners within the listed 2009–2014 range can consider this six-inch spring for progressive construction and stated OE-or-greater capacity. Its application is specific, so other trucks and trailer axles fall outside the supplied fit information.

#4 · Best American Steel

4. Skyjacker CR16S Softride

• Weight: 63 lb

Best for: Progressive-pack suspension buyers.

Why it ranks #4: A 6-inch Softride spring made with American steel and progressive multileaf packs; its listing says load capacity is equal to or greater than OE.

Progressive multileaf construction sets the Skyjacker CR16S apart, pairing a six-inch leaf spring with a load capacity stated as equal to or greater than OE. That combination gives buyers prioritizing progressive pack construction and load support a clear basis for considering this Softride spring.

Skyjacker specifies American steel and says the individual leaves are shot-peened with hard steel pellets, a process described as compressing the steel surface to increase tensile strength. That construction detail gives durability-minded buyers more context than a spring label alone. The progressive multileaf pack and stated OE-or-greater load capacity speak to load support, while the CR16S is identified as a six-inch Softride spring. Vehicle application details are not supplied here, so match the spring to the intended setup before selection.

Skip it if you need a spring explicitly listed for a 2009–2014 Ford F-150; Skyjacker FR904S names that application.

Choose the CR16S if progressive multileaf construction, American steel, and its stated load-capacity relationship to OE matter to your spring selection. The supplied product details do not name a vehicle application, so that fit remains a key boundary.

#5 · Highest Capacity

5. dreamdragon Trailer Leaf Springs

• Weight: 160 lb

Best for: 7,000-pound trailer axle setups.

Why it ranks #5: The two six-leaf trailer springs are rated at 3,500 pounds each for 7,000-pound axles and list 25-1/4-inch eye-to-eye length.

A 3,500-pound rating per spring makes this two-piece dreamdragon set a specified match for standard 7,000-pound trailer axles. Its six-leaf, double-eye construction gives trailer owners a clearly described spring configuration, with dimensions included to compare against an existing suspension setup.

Each spring is rated at 3,500 pounds, and the listing identifies the pair with standard 7,000-pound axles, connecting the capacity to a defined trailer application. The 25-1/4-inch eye-to-eye length, 1-3/4-inch width, and 9/16-inch bushing diameter provide useful measurements for matching suspension hardware. A six-leaf double-eye design is also described as distributing load and supporting trailer stability. The stated 3-inch free open height adds another dimension to check when planning replacement.

Skip it if you need a 3,300-pound-per-spring rating; SOUTHWEST WHEEL SW6 lists that capacity.

Trailer owners replacing springs on a standard 7,000-pound axle can use the per-spring rating and listed dimensions to guide selection. Check eye-to-eye length, width, and bushing diameter against the suspension, and keep the 3,500-pound rating in scope.

#6

6. SEHNSUCHT Trailer Leaf Springs

• Weight: 36.7 lb

Best for: SW6-style trailer replacements.

Why it ranks #6: A two-piece six-leaf trailer replacement rated at 3,500 pounds per spring, with 25-1/4-inch eye-to-eye length and 1.75-inch width.

A stated replacement match for SW6 gives this SEHNSUCHT spring set a useful reference point for trailer owners. The two-piece, six-leaf double-eye configuration is rated at 3,500 pounds per spring for 7,000-pound trailer axles, with key dimensions supplied for comparison.

The 25-1/4-inch eye-to-eye length and 1-3/4-inch width help buyers compare the springs with an existing trailer setup, while the 9/16-inch bushing diameter adds another hardware measurement. Each spring is rated at 3,500 pounds, and the listing identifies the pair for a standard 7,000-pound axle. Heavy-duty carbon steel is cited as the material, with transmission stability and friction damping named as design aims. The listed 3-inch free-open measurement supports dimensional planning.

Skip it if you need a 3,300-pound-per-spring spring instead; SOUTHWEST WHEEL SW6 lists that rating.

Trailer owners replacing an SW6-style spring on a 7,000-pound axle can use the capacity and supplied dimensions as selection checks. The 3,500-pound-per-spring rating and 9/16-inch bushing detail define important boundaries for the match.

#7

7. SOUTHWEST WHEEL Trailer Springs

• Weight: 32 lb

Best for: 3,300-pound trailer spring pair.

Why it ranks #7: This two-pack six-leaf trailer spring lists 25-1/4-inch eye-to-eye length, 1-3/4-inch width, and 3,300-pound capacity per spring.

The 3,300-pound-per-spring rating is the key differentiator of this SOUTHWEST WHEEL two-pack, giving trailer owners a specific capacity to compare with their axle setup. Its six-leaf, double-eye design and 25-1/4-inch eye-to-eye length provide additional details for replacement planning.

This set includes two six-leaf double-eye springs, so buyers can plan around the listed pair rather than a single spring. Each spring is rated at 3,300 pounds, and the 1-3/4-inch width plus 25-1/4-inch eye-to-eye measurement help with dimensional comparison during replacement. The listing does not provide a bushing diameter or free-open height, so those details are not available here for checking against a trailer’s existing suspension. The stated capacity is the central selection figure.

Skip it if you need 3,500 pounds per spring for a 7,000-pound axle; dreamdragon JHLS000006 lists that rating.

This set suits trailer owners whose suspension calls for the listed 3,300-pound-per-spring capacity and double-eye form. Use the 25-1/4-inch length and 1-3/4-inch width as comparison points; the listing does not supply every fit dimension.

#8

8. Magorfas Trailer Leaf Spring

• Weight: 19.76 lb

Best for: Multiple trailer axle ratings.

Why it ranks #8: A 25-1/4-inch, six-leaf trailer replacement listed for SW6 fit; additional facts give capacity options for 5,000-, 6,000-, and 7,000-pound trailers.

Three per-spring capacity figures distinguish this Magorfas trailer leaf spring listing: 2,500 pounds for 5,000-pound trailers, 3,000 for 6,000-pound trailers, and 3,500 for 7,000-pound trailers. The six-leaf double-eye format and 25-1/4-inch length provide further selection details.

The capacity options give buyers a way to relate the spring to several stated trailer ratings, rather than relying on a single load figure. Magorfas identifies a six-leaf double-eye spring with a 25-1/4-inch length and says it fits SW6, giving owners a reference for replacement planning. The listing does not provide width, arch, or bushing diameter, so those dimensions cannot be compared from the supplied details. Match the stated capacity to the trailer rating and check the available length information.

Skip it if you need listed width and bushing-diameter measurements; SEHNSUCHT SCLS0015CK01 provides both.

Trailer owners weighing the three stated axle-capacity figures can use this Magorfas listing to narrow a replacement choice, especially for an SW6 reference. Its length is supplied, but width, arch, and bushing diameter remain fit considerations.

#9

9. FWN-052 Leaf Spring

• Weight: 15.52 lb

Best for: 2,500-pound trailer spring needs.

Why it ranks #9: This is a five-leaf, 26-inch trailer spring with 1-3/4-inch width and 2,500-pound capacity, not a 6-inch truck spring or six-leaf set.

A 26-inch length and 4-1/4-inch arch define this FWN five-leaf double-eye spring, giving trailer owners two concrete dimensions for a replacement comparison. Its listed maximum load capacity is 2,500 pounds, making the capacity an essential part of evaluating the intended setup.

The 1-3/4-inch width and 26-inch length offer straightforward measurements to compare with an existing spring, while the 4-1/4-inch arch adds a profile dimension for the setup. FWN specifies five leaves and a maximum 2,500-pound load capacity, so buyers can assess both construction and stated load limit together. The listing identifies a double-eye design, but does not provide eye-to-eye length or bushing diameter. That makes the supplied dimensions useful, though not a complete fit specification.

Skip it if you need 3,500 pounds per spring for a 7,000-pound axle; Magorfas MFLS0014Q1 lists that capacity.

This spring fits consideration for buyers whose requirements align with its 2,500-pound maximum and listed dimensions. Compare the 26-inch length, arch, and width with the existing setup; eye-to-eye length and bushing diameter are not supplied.
