Best 5 Leaf Springs For Trailer: 10 Options Compared

#1 · Best Overall

1. Aeagle 5 Leaf Spring Set

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

Best for: Round-axle SW5 replacements.

Why it ranks #1: Four SW5 replacement double-eye springs suit 5,200–6,000-pound axles, with 3,000-pound capacity each and a 25-1/4-inch eye-to-eye length.

Four springs in the kit make the Aeagle a practical option for replacing a set rather than sourcing individual corners. Each is rated at 3,000 pounds, with 25-1/4-inch eye-to-eye length and 1-3/4-inch width, for round-axle trailers in the stated 5,200–6,000-pound range.

The five-leaf, 3,000-pound-per-spring rating gives buyers a defined capacity for the listed 5,200–6,000-pound trailer axles. Its 25-1/4-inch eye-to-eye measurement, 3-inch free open, and 9/16-inch bushing diameter provide useful dimensions for checking the existing suspension before installation. The four-spring quantity supports a set replacement, while the electroplated anti-rust coating is intended to resist corrosion during service. The listing specifies round axles only, so axle shape is a decisive fit boundary.

Skip it if you have a square axle; the listing restricts these springs to round axles, while the SEHNSUCHT SW5 kit includes additional suspension hardware.

Choose this four-spring set when replacing round-axle SW5-style suspension within the stated capacity range and dimensions. Its anti-rust coating is useful for corrosion resistance, but the square-axle exclusion is a firm boundary.

Best for: Complete tandem hardware kit.

Why it ranks #2: Includes four 3,000-pound SW5 springs plus U-bolts, tie plates, and nuts for 5,200–6,000-pound tandem trailer axles.

The kit’s four 3,000-pound springs cover the listed 5,200–6,000-pound tandem axle range, while the 25-1/4-inch length, 1-3/4-inch width, and 9/16-inch bushing diameter help compare the springs with the existing setup. Hardware includes four 7-inch U-bolts, two tie plates, and eight hex nuts; the U-bolts are specified for 3-inch round axles. The listing warns that nuts must be tightened horizontally, making correct installation orientation part of the job.

Skip it if you need only a pair of springs without a full hardware bundle; the Youxmoto LFLS0009-LYF pair provides SW5-style replacement springs.

Choose this kit for a tandem suspension replacement when four springs and mounting hardware are useful together. Its U-bolts are specified for 3-inch round axles, and installation requires horizontal nut orientation.

#3 · Best Cross-Compatible Pair

3. Trailer Supplies SW5 Pair

• Weight: 24.7 lb

Best for: Cross-compatible SW5 replacements.

Why it ranks #3: The pair is rated at 3,000 pounds per spring and lists compatibility with SW5, PR5, LIB-502-DE, and EMCO DE-SW5.

Compatibility with Dexter SW5/PR5, LIB-502-DE, and EMCO DE-SW5 distinguishes these TRAILER SUPPLIES springs for buyers matching common double-eye replacements. The pair supplies two five-leaf springs rated at 3,000 pounds each, with 25.25-inch length and 1-3/4-inch width for 5,200–6,000-pound axles.

Each spring’s 3,000-pound rating supports the listed 5,200–6,000-pound axle application, while the 25.25-inch length and 1-3/4-inch width give buyers concrete dimensions to compare. The named cross-compatibility references can streamline identification when replacing a Dexter SW5/PR5 or the other listed models. Two springs are included, making this a pair rather than a full four-spring kit. The listing identifies utility, boat, and equipment trailers as applications, with single-axle and tandem setups mentioned.

Skip it if you need four springs and tandem mounting hardware together; the Youxmoto LFLS0011-LYF kit includes four springs, U-bolts, and tie plates.

Choose this pair when replacing compatible SW5-style double-eye springs on a stated 5,200–6,000-pound axle. Its cross-reference list helps identify the application, while the two-spring quantity is the main boundary for tandem jobs.

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)

4. Youxmoto SW5 Pair

• Weight: 31.9 lb

Best for: Manganese-steel SW5 pair.

Why it ranks #4: A pair of 5-leaf double-eye springs provides 3,000 pounds per spring, with SW5 fitment and a 25-1/4-inch eye-to-eye length.

60Si2Mn manganese-steel construction is the Youxmoto pair’s clearest material distinction, supporting strength and transmission stability in its stated trailer application. Each five-leaf spring is rated at 3,000 pounds for a 6,000-pound axle, with a 25-1/4-inch eye-to-eye length and 9/16-inch bushing diameter.

The pair’s 3,000-pound capacity per spring is specified for 6,000-pound trailers, while its 25-1/4-inch eye-to-eye length and 1-3/4-inch width provide concrete checks against an existing SW5 setup. A 3-inch free-open measurement and 9/16-inch bushing diameter further define the fit. Five leaves and 60Si2Mn manganese steel are identified as strength and stability features, and an extra rust-proof coating is intended to handle harsher environments. Two springs suit a pair replacement, not a four-spring kit.

Skip it if you need springs and tandem mounting hardware together; the Youxmoto LFLS0011-LYF package includes four springs, U-bolts, and tie plates.

This pair fits buyers replacing two SW5-style springs on a stated 6,000-pound trailer axle. Its detailed dimensions aid comparison, while the two-piece quantity and listed capacity define the important limits for a full suspension job.

5. Magorfas SW5 Set

• Package Dimensions: 28.25 x 10 x 4.5 in
• Weight: 31.5 lb

Best for: Two-spring 6,000-pound axle.

Why it ranks #5: These two double-eye springs are rated at 3,000 pounds each for 6,000-pound axles and list a 25-1/4-inch length and SW5 fitment.

A two-spring set rated at 3,000 pounds per spring gives the Magorfas a clearly stated application for 6,000-pound trailer axles. Its title identifies a five-leaf, double-eye configuration measuring 25-1/4 inches, which helps buyers compare the replacement with an SW5-style suspension before committing to installation.

The 3,000-pound rating per spring establishes the capacity for the listed 6,000-pound axle application, while the five-leaf double-eye design identifies the suspension style. The 25-1/4-inch length and SW5 fit reference offer practical comparison points when matching existing components. This is a set of two, making it relevant when replacing a pair rather than assembling a four-spring kit. The supplied information gives no further dimensions or material details, so verify the remaining requirements against the product listing before selection.

Skip it if you need a four-spring tandem kit with installation hardware; the Youxmoto LFLS0011-LYF includes four springs, U-bolts, and tie plates.

Consider this pair when the trailer uses a five-leaf, double-eye spring and the stated 6,000-pound axle capacity. Its listed length and SW5 reference help with comparison, but other fit dimensions are not supplied here.

• Weight: 93.8 lb

Why it ranks #6: The springs match the 3,000-pound-per-spring SW5 specification for 5,200–6,000-pound axles, and the listing includes U-bolt and hanger components.

#7

7. FWN 5 Leaf Spring

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

Best for: Vibration-conscious road hauling.

Why it ranks #7: Its 25.25-inch length, 1.75-inch width, and 3,000-pound capacity align with the common SW5 size, but the listing gives no pack count.

FWN highlights high-strength, high-toughness manganese steel and vibration absorption, giving this five-leaf spring a road-use focus for protecting trailer cargo and the hitch system. The listed specifications identify a 25.25-inch length, 1.75-inch width, 3.13-inch arch, and 3,000-pound capacity.

Its 3,000-pound capacity and 25.25-inch length offer primary checks for buyers matching a replacement to a trailer setup. The 1.75-inch width and 3.13-inch arch add further dimensions for comparing the installed spring. FWN identifies manganese steel as high strength and toughness, and says the spring absorbs road vibrations to protect the trailer hitch system and cargo. The supplied details do not identify eye style or bushing dimensions, so those fit points require separate confirmation from the full listing.

Skip it if you require stated double-eye and bushing measurements; the Aeagle AELS0010Q4 lists both along with its SW5 replacement dimensions.

This FWN spring may suit buyers prioritizing its stated vibration-absorption benefit and matching 25.25-inch dimensions. Its capacity, width, and arch are listed, but eye style and bushing dimensions are not included in the supplied specifications.

8. ikare 3500 Spring

• Weight: 30.9 lb

Best for: Standard 3,500-pound trailers.

Why it ranks #8: This five-leaf double-eye spring is specified for a 3,500-pound axle, with 1,650-pound capacity per spring and a 25.2-inch length.

The ikare spring is specified for a standard 3,500-pound trailer axle, with a 1,650-pound capacity per spring. Its five-leaf double-eye configuration and 25.2-inch length offer a defined starting point for replacing a damaged spring on a utility or boat trailer.

The 1,650-pound per-spring rating is explicitly associated with a standard 3,500-pound trailer axle, helping buyers assess the stated application. Its 25.2-inch length, 1.8-inch width, and five-leaf double-eye construction provide practical comparison points during replacement planning. The listed bushing diameter is 9/16 inch, with an eye diameter of 10/16 inch without the bushing. Because the supplied details do not state a material or coating, the decision centers on capacity and dimensions rather than those attributes.

Skip it if you need 3,000 pounds of capacity per spring; the Aeagle AELS0010Q4 is specified at 3,000 pounds per spring for larger trailer axles.

This spring suits buyers matching the stated 3,500-pound axle application and 1,650-pound per-spring rating. Compare its 25.2-inch length, width, and eye measurements with the existing double-eye setup before choosing a replacement.

#9 · Best 7000-Pound Axle

9. dreamdragon Slipper Set

• Weight: 160 lb

Best for: Heavy-duty 7,000-pound axles.

Why it ranks #9: Four slipper springs rated at 3,500 pounds each target 7,000-pound axles, but their 2-inch width and hook-end length differ from SW5 double-eye springs.

A 3,500-pound rating per spring gives the dreamdragon four-pack a higher stated capacity than 3,000-pound replacement springs. Its five-leaf slipper design is listed for 7,000-pound axles, with a 26-7/8-inch eye-center-to-hook length, 2-inch width, and 9/16-inch bushing diameter.

The four-piece quantity supports a set replacement, while the 3,500-pound capacity per spring is specified for 7,000-pound trailer axles. The 26-7/8-inch length from eye center to hook end and 2-inch leaf width help buyers compare the slipper springs with their current suspension. A 3.19-inch free-open height and 9/16-inch bushing diameter add useful fit measurements. The 60Si2Mn manganese-steel construction is described as providing strength, flexibility, and hardenability; the slipper layout remains a key compatibility constraint.

Skip it if you need a double-eye replacement for a 5,200–6,000-pound axle; the Aeagle AELS0010Q4 is specified for that capacity and spring style.

Consider this four-pack for a compatible slipper suspension on a 7,000-pound axle, especially when its 3,500-pound spring rating matches the application. Check the hook-end length, width, and bushing measurement against the existing setup.

#10 · Best 10000-Pound Axle

10. M-Parts 10K Slipper Spring

• Package Dimensions: 34 x 8 x 3 in
• Weight: 36 lb

Best for: 10,000-pound slipper axle.

Why it ranks #10: This 5-leaf slipper spring is rated at 5,000 pounds for a 10,000-pound axle, with a 32.5-inch length and 2.5-inch width.

A 10,000-pound axle application separates this M-Parts slipper spring from the many 5,200–6,000-pound double-eye replacements. It has five leaves, a 32.5-inch length measured from the eye center to the slipper end, and a 2-1/2-inch width, with a 5,000-pound spring rating.

The 5,000-pound capacity per spring is specified for a 10,000-pound trailer axle, giving heavy-axle buyers a clear load application. Its 32.5-inch eye-to-slipper measurement and 2-1/2-inch width provide key comparison points for an existing slipper suspension. The 3/4-inch spring eye includes a rubber bushing, a configuration that helps identify the connection interface during replacement planning. Five leaves complete the listed construction. This is a slipper-style spring, so it is not an interchangeable double-eye option based on the supplied details.

Skip it if you have a 5,200–6,000-pound axle with double-eye springs; the Aeagle AELS0010Q4 set is specified for that axle range and style.

This spring suits buyers replacing a compatible slipper-style spring on a 10,000-pound axle. Match its 32.5-inch measurement, 2-1/2-inch width, and 3/4-inch bushed eye to the existing suspension before selecting it.
