FWN-015 940LB 4 Leaf Trailer Leaf Spring

The FWN-015 trailer leaf spring is a 4-leaf suspension spring designed for utility trailer applications requiring dependable load support and consistent suspension performance. With a rated capacity of 940 lb per spring, it provides a practical solution for trailer axle suspension while maintaining a compact and durable construction. Its flat end slipper design allows the spring to work with compatible trailer suspension components for stable movement and load distribution.

Durable 4 Leaf Construction

This trailer leaf spring features a four-leaf laminated construction that allows the individual spring leaves to work together when the trailer is carrying a load. The layered design provides the flexibility needed to absorb road impacts while supporting the axle during regular towing conditions. With a 1.75-inch leaf width, the spring offers a balanced structure suitable for compatible utility trailer suspension applications.

Flat End Slipper Design

The flat end slipper configuration provides a different mounting arrangement from traditional double-eye leaf springs. Instead of using an eye at both ends, the slipper end engages with the corresponding trailer suspension hardware, allowing controlled movement as the spring flexes. This design is commonly used on utility trailers where the suspension layout requires a slipper-style leaf spring.

Practical Dimensions for Trailer Replacement

With an overall length of approximately 25 1/8 inches and a leaf width of 1 3/4 inches, the FWN-015 is designed for applications requiring a compatible compact trailer suspension spring. Before replacement, buyers should compare the spring length, width, mounting configuration, capacity, and bushing arrangement with the original component to ensure proper fit and suspension performance.

Reliable Load Support for Utility Trailers

Each spring is rated for a 940 lb capacity, making this trailer axle leaf spring suitable for compatible utility trailer suspension applications. Properly matched leaf springs help distribute axle loads and absorb road shock during towing. Selecting the correct capacity is essential because an unsuitable spring may negatively affect ride characteristics, suspension movement, and the service life of related components.

Bushing and Specification Details

The spring is supplied with a PE-227 bushing configuration and uses a four-leaf arrangement. These specifications are important when replacing an existing leaf spring because bushing compatibility affects how the spring connects with the trailer's suspension hardware. Buyers should verify the complete suspension arrangement before ordering replacement components.

Suitable for Replacement and Trailer Assembly

The FWN-015 trailer leaf spring can be considered for replacement projects and compatible utility trailer suspension assemblies. Its four-leaf structure, slipper-end configuration, and defined load rating make it easier for trailer manufacturers, distributors, and replacement-part suppliers to identify the appropriate suspension component for their requirements.

When installing a replacement trailer leaf spring, the complete suspension assembly should be inspected rather than replacing the spring alone without checking related components. Hangers, shackles, bushings, bolts, and other mounting parts should be examined for wear or damage. Correct installation and proper matching of suspension components help maintain stable towing performance and extend component service life.

Why Choose FWN Trailer Leaf Springs

FWN provides trailer suspension components for different trailer applications, including leaf springs with various configurations and load capacities. The FWN-015 combines a 4-leaf construction, 940 lb capacity, 25 1/8-inch length, and 1 3/4-inch width into a practical solution for compatible utility trailer applications. For distributors and trailer manufacturers, clearly defined specifications also make product selection and replacement sourcing more efficient.

For customers requiring a trailer leaf spring with a flat end slipper design, the FWN-015 offers a straightforward option when its dimensions and load rating correspond to the existing trailer suspension. Confirming the original spring specifications before installation remains essential for achieving proper fit, safe load support, and reliable towing performance.
