Best 5 Leaf Springs For Trailer: Compare 10 Replacement Options

#1 · Best Overall

1. TRAILER SUPPLIES 25.25-Inch Spring

• Weight: 24.7 lb

Best for: Cross-reference SW5 replacement.

Why it ranks #1: This pair rates each spring at 3,000 pounds and lists SW5, PR5, LIB-502-DE, and EMCO DE-SW5 compatibility for common 5,200–6,000-pound axles.

Multiple named replacement references give this TRAILER SUPPLIES pair a useful compatibility profile: the listing cites Dexter SW5/PR5, LIB-502-DE, and EMCO DE-SW5. Each 25.25-inch, 1-3/4-inch-wide spring is rated at 3,000 pounds for specified 5,200–6,000-pound axles.

The double-eye configuration, 25.25-inch length, and 1-3/4-inch width make the pair’s dimensions explicit for a replacement comparison. Its 3,000-pound rating per spring is stated for 5,200–6,000-pound trailer axles and is relevant to utility, boat, and equipment trailer applications in the listing. The cross-reference list can simplify part identification across several named spring models, while the two-spring quantity suits a pair replacement rather than a four-spring kit.

Skip it if you need four springs plus axle mounting hardware; Youxmoto LFLS0011-LYF includes four springs with U-bolts and tie plates.

This pair suits buyers matching a 25.25-inch double-eye replacement against the listed SW5, PR5, LIB-502-DE, or EMCO references. It covers a pair replacement; a full tandem refresh requires additional springs and any needed hardware.

Listed on Amazon as: Pair of 25.25" 5-Leaf Double Eye Trailer Springs 1-3/4" Wide for 5,200–6,000 lb Axles (Single Axle – 3,000 lbs per Spring) SW5 (2 Springs)

#2 · Four-Spring Pack

2. LIBRA 5-Leaf Spring

• Package Dimensions: 27 x 11 x 6 in
• Weight: 62 lb

Best for: LIBRA four-spring replacement.

Why it ranks #2: Its PK4 pack provides four 3,000-pound springs with 25-1/4-inch length, 1-3/4-inch width, and several listed SW5 replacement references.

A four-spring pack gives LIBRA buyers a way to replace a complete matching set, with each five-leaf spring rated at 3,000 pounds. The stated 25-1/4-inch length, 1-3/4-inch width, and SW5 replacement references target standard 5,200–6,000-pound trailer axles.

The four-piece quantity is practical for a full replacement, while the 25-1/4-inch eye-to-eye length, 1-3/4-inch width, and 9/16-inch bushing diameter provide dimensional checks. LIBRA lists compatibility references including SW5, LIB-502-DE, UNA111, PR5, 9150018, and 93163. Each spring’s 3,000-pound capacity is specified for standard 5,200–6,000-pound axles, helping buyers compare the pack against their axle class and existing spring configuration.

Skip it if you need installation hardware bundled with the springs; Youxmoto LFLS0011-LYF lists four springs with U-bolts and tie plates.

LIBRA’s pack suits a buyer replacing four matching SW5-style springs on a 5,200–6,000-pound trailer axle. Its dimensions and cross-references help narrow compatibility, but the listing describes springs rather than a hardware-complete suspension kit.

#3 · Complete Spring Set

3. Aeagle 5-Leaf Spring

• Package Dimensions: 29 x 12 x 6 in
• Weight: 63.8 lb

Best for: Four-spring round-axle set.

Why it ranks #3: Four 3,000-pound SW5 replacement springs suit 5,200–6,000-pound round axles, and the listing specifies 25-1/4-inch length and 9/16-inch bushings.

Four springs arrive in this Aeagle kit, each rated at 3,000 pounds for listed 5,200–6,000-pound trailer axles. The 25-1/4-inch length, 1.75-inch width, and explicit round-axle-only note make its application boundaries unusually clear before a buyer plans installation.

The four-piece quantity suits a full set replacement, while the 9/16-inch bushing diameter and 25-1/4-inch eye-to-eye length supply dimensions for checking the existing suspension. Aeagle specifies fit for round axles and explicitly excludes square axles, a critical selection limit. Its anti-rust coating is described as improving corrosion resistance, and 60Si2Mn manganese steel is associated with stable elasticity and shock absorption for a smoother, more stable trailer ride.

Skip it if you have a square axle; Youxmoto LFLS0011-LYF lists a kit for 3-inch-diameter round axles, so it also requires a round-axle setup.

Choose the Aeagle four-pack for a matching round-axle trailer in the stated 5,200–6,000-pound range, especially when replacing all four springs. Its square-axle exclusion is explicit, and the listed dimensions should guide suspension matching.

Listed on Amazon as: Aeagle 5 Leaf 3000lb Capacity Double Eye Spring for 5200lb-6000lb Trailer Axle, 25-1/4" Length, 1.75" Width, 3" Free Open Replaces SW5, 4 PCS

#4 · Hardware-Included Kit

4. Youxmoto Suspension Kit

• Weight: 89.8 lb

Best for: Tandem axle hardware bundle.

Why it ranks #4: This four-spring kit rates each spring at 3,000 pounds and adds U-bolts, tie plates, and nuts for a 3-inch-diameter round axle.

A complete hardware bundle sets this Youxmoto kit apart: four five-leaf springs come with U-bolts, tie plates, nuts, and hanger-kit accessories. Its stated 3,000-pound capacity per spring and SW5 replacement reference target tandem trailer suspension work without sourcing every mounting component separately.

The four springs are specified for 5,200–6,000-pound tandem axles, and the included U-bolt kit is for 3-inch-diameter round trailer axles. Four 7-inch U-bolts, tie plates for 1-3/4- or 2-inch springs, and eight nuts provide listed mounting components for the job. The instructions also stress tightening nuts horizontally, a practical installation detail that buyers must follow for proper use.

Skip it if you only need two springs and no mounting hardware; Youxmoto LFLS0009-LYF is a two-spring SW5 replacement pair.

This bundle fits a buyer refreshing a tandem suspension who wants springs and listed mounting hardware together. Its U-bolts are specified for 3-inch round axles, and the horizontal nut-tightening instruction is an installation consideration.

Listed on Amazon as: 4pcs 5 Leaf Springs 3000lb, for 5200lb-6000lb Tandem Trailer Axle Suspension Kit & U-Bolt & Hanger Kit; 25-1/4" L, 1-3/4" Width, 9/16" Bushing Dia, Fits for SW5

#5

5. Youxmoto Double-Eye Pair

• Weight: 31.9 lb

Best for: SW5 pair with rust protection.

Why it ranks #5: The pair gives a clear 3,000-pound-per-spring rating, 25-1/4-inch eye-to-eye length, 1-3/4-inch width, and 9/16-inch bushings.

An added rust-proof coating is the Youxmoto pair’s specific environmental feature, accompanying two five-leaf springs rated at 3,000 pounds each. The 25-1/4-inch eye-to-eye length, 1-3/4-inch width, and 9/16-inch bushing diameter provide concrete references for matching an SW5-style replacement.

The stated SW5 replacement and 25-1/4-inch eye-to-eye length help identify the intended configuration, while the 1-3/4-inch width and 9/16-inch bushing diameter give further dimensions to check against existing hardware. Each spring carries a 3,000-pound rating, which the listing associates with 6,000-pound trailers. The five-leaf 60Si2Mn manganese-steel construction is described as supporting transmission stability, and an added rust-proof coating is cited for harsh environments.

Skip it if you want a four-spring tandem kit with mounting hardware included; Youxmoto LFLS0011-LYF lists four springs, U-bolts, and a hanger kit.

This pair suits an SW5 replacement on a 6,000-pound trailer where the listed length, width, and bushing diameter match. The coating and steel construction are relevant features, but buyers replacing all four springs must source a separate pair.

Listed on Amazon as: Pair of Trailer Leaf Spring- 5 Leaf Double Eye 3000lbs for 6000 Lbs Axle, 25-1/4" L, 1-3/4" Width, 9/16" Bushing Dia, Fits for SW5; 2pcs

#6

6. Magorfas Double-Eye Pair

• Package Dimensions: 28.05 x 10.03 x 4 in
• Weight: 30.5 lb

Best for: 6000-pound axle replacement.

Why it ranks #6: This two-spring set specifies five leaves and 3,000 pounds per spring for a 6,000-pound trailer, though fewer fit dimensions are provided.

A 3,000-pound rating per spring gives this Magorfas double-eye pair a clear role on trailers with 6,000-pound axles. Its five-leaf SW5-style configuration provides a concrete replacement option for owners seeking that capacity and a 25-1/4-inch spring length, rather than a higher-rated slipper design.

The 25-1/4-inch length identifies the key dimensional target, while the double-eye layout distinguishes this spring from slipper-end alternatives. Its 3,000-pound capacity per spring is specified for 6,000-pound trailers, giving buyers a straightforward capacity reference when planning a pair replacement. The set contains two springs, and each weighs 30.5 pounds according to the listing. The SW5 designation offers an additional reference point for comparing the replacement configuration with existing parts.

Skip it if you need a stated leaf width and bushing diameter; TRAILER SUPPLIES WA-111-1PAIR lists both a 1-3/4-inch width and exact SW5 compatibility.

Choose this pair if your trailer uses the listed 25-1/4-inch, double-eye SW5-style springs and needs 3,000 pounds of capacity per spring. The listing does not provide width or bushing diameter, so those dimensions remain a fit consideration.

#7

7. FWN 25.25-Inch Spring

• Package Dimensions: 27 x 4.5 x 2.5 in
• Weight: 16.37 lb

Best for: Compact 3000-pound spring.

Why it ranks #7: It matches the common 25.25-inch length and 1.75-inch width, with five leaves and a 3,000-pound capacity per spring.

At 16.37 pounds, the FWN five-leaf spring is the lightest single spring in this group with a stated 3,000-pound capacity. Its 25.25-inch length, 1.75-inch width, and 3.13-inch arch give buyers a useful dimensional profile for replacing a matching trailer spring.

The 25.25-inch length and 1.75-inch width help establish the spring’s installation envelope, while the 3.13-inch arch is another important comparison point for a matching suspension. FWN lists a 3,000-pound capacity, so the spring’s rating can be weighed against the trailer’s axle requirements. Its high-strength, high-toughness manganese steel is cited for service life, and the description says the spring absorbs road vibration to help protect the hitch system and cargo.

Skip it if you need four springs and tandem-axle hardware in one purchase; Youxmoto LFLS0011-LYF lists four springs with U-bolts and hanger-kit accessories.

Consider the FWN spring when replacing one matching 3,000-pound, 25.25-inch spring and when its 1.75-inch width and 3.13-inch arch suit the setup. The listing specifies a single spring, so buyers needing a pair or kit should account for that.

Listed on Amazon as: FWN Trailer Leaf Spring, 5 Leaf, 25.25"L, 1.75" W, 3.13" Arch, 3000lb Capacity

#8 · Slipper-Style Pick

8. dreamdragon Slipper Spring Set

• Package Dimensions: 30 x 20 x 20 in
• Weight: 160 lb

Best for: 7000-pound axle slipper setup.

Why it ranks #8: This five-leaf slipper pair is rated at 3,500 pounds per spring for a 7,000-pound axle, with a 2-inch width and 26-7/8-inch free length.

A 3,500-pound rating per spring positions the dreamdragon slipper set for 7,000-pound trailer axles. The 26-7/8-inch eye-to-hook free length and 2-inch leaf width give buyers specific dimensions to compare with an existing slipper spring, while the five-leaf layout and manganese-steel material define its construction.

The slipper end differs from a double-eye arrangement, so its 26-7/8-inch eye-to-hook measurement is the relevant length reference for matching a similar setup. A 2-inch leaf width and 9/16-inch bushing diameter add useful comparison dimensions before installation. Each spring is rated at 3,500 pounds, aligning the pair with the stated 7,000-pound axle use. The listed 60Si2Mn manganese steel is described as offering strength, flexibility, and hardenability.

Skip it if you have a double-eye suspension rather than a slipper end; Magorfas MFLS0009Q2-L is listed as a double-eye 6,000-pound-axle spring.

This set suits buyers replacing slipper springs on a 7,000-pound axle who can match its eye-to-hook length, 2-inch width, and bushing measurement. Its slipper configuration is the central boundary; it is not the double-eye style listed by many alternatives.

#9

9. Dorman 929-1033 Spring

• Weight: 16.27 lb

Best for: Direct replacement repair.

Why it ranks #9: The five-leaf eye-to-eye spring lists a 2,500-pound capacity, 26-inch length, and 1-3/4-inch width, making it less aligned with 3,000-pound replacements.

Dorman specifies a 26-inch eye-to-eye length and 4 1/4-inch arch for this five-leaf utility-trailer spring, making it a defined replacement option for applications matching those dimensions. Its 2,500-pound capacity and 1 3/4-inch width set clear boundaries for buyers comparing repair parts.

The eye-to-eye design and 26-inch length provide the main fit references, while the 4 1/4-inch arch helps distinguish it from lower-arch alternatives. Dorman describes the spring as a direct replacement for specific vehicle or trailer applications and cites overloading, collision, cracking, and corrosion as reasons for replacement. At 2,500 pounds capacity, it is intended for a different load range than 3,000-pound-per-spring options; matching the application remains essential.

Skip it if you require 3,000 pounds per spring; LIBRA SW5 lists that capacity for standard 5,200–6,000-pound trailer axles.

This Dorman suits a repair where a 26-inch, 1 3/4-inch-wide, 4 1/4-inch-arch spring and 2,500-pound rating match the application. Its direct-replacement positioning is useful, but the dimensions and capacity define a narrower fit than higher-rated choices.

Listed on Amazon as: Dorman 929-1033 Utility Trailer Leaf Spring, Eye/Eye, 1 3/4" Width, 26" Length, 4 1/4" Arch, 5 Leaf, 2500lb Capacity

#10

10. ikare 5-Leaf Spring

• Package Dimensions: 27.5 x 9.5 x 3 in
• Weight: 30.9 lb

Best for: 3500-pound axle spring.

Why it ranks #10: Its 1,650-pound spring capacity is specified for a standard 3,500-pound axle, a substantially lower rating than the common 5,200–6,000-pound options.

A 1,650-pound capacity per spring makes this ikare five-leaf option distinct from the 3,000-pound models, with the listing identifying it for a standard 3,500-pound trailer axle. Its 25.2-inch length and 1.8-inch width provide key dimensions for a matching replacement.

The stated 1,650-pound capacity per spring is the central load reference, and the product description connects it to a standard 3,500-pound axle. A 25.2-inch eye-to-hook measurement, 1.8-inch width, and 9/16-inch bushing diameter help buyers compare the spring with existing parts. The five-leaf construction is specified, and the description identifies overloading, collision, cracking, and corrosion as possible reasons a damaged trailer spring may need replacement.

Skip it if you need 3,000 pounds per spring for a 5,200–6,000-pound axle; LIBRA SW5 lists that higher per-spring capacity.

This ikare spring suits a matching 3,500-pound-axle application where its 1,650-pound rating and listed dimensions align with the existing suspension. It is not the choice among these options for buyers seeking a 3,000-pound spring rating.
