Description
4 Leaf Trailer Leaf Spring for Utility Trailers
The FWN-024 trailer leaf spring is a 4-leaf suspension spring designed for utility trailer applications requiring dependable load support and consistent suspension performance. With a 1100 lb capacity per spring, it provides a practical replacement option for trailer suspension assemblies where accurate load matching and reliable fitment are important.
Featuring a radius-end slipper configuration, this leaf spring is designed to work with compatible trailer suspension components while allowing controlled spring movement during towing. Its 1 3/4-inch leaf width provides a substantial load-bearing surface, making it suitable for a range of utility trailer suspension applications.
1100Lb Load Capacity and 4-Leaf Construction
The FWN-024 uses a 4-leaf configuration with a rated capacity of 1100 lb. Selecting a leaf spring according to the required axle and load rating is essential for maintaining balanced suspension performance. Using the correct capacity helps the trailer suspension respond appropriately to loaded and unloaded conditions.
The 4-leaf construction provides a balance between load support and suspension flexibility. For replacement applications, buyers should compare the existing spring configuration, axle requirements, dimensions, and mounting components before ordering to ensure compatibility.
Radius End Slipper Design
This radius end slipper leaf spring uses a slipper-style end configuration rather than a traditional eye at both ends. The design is commonly used in trailer suspension arrangements where the spring end slides within a compatible hanger or equalizer assembly as the suspension moves.
The end configuration should always be matched with the existing trailer suspension hardware. The FWN-024 is supplied with a PE-226 bushing at End 1, providing a defined connection point for compatible mounting components. Checking the bushing, hanger, shackle, and equalizer arrangement before replacement can help avoid installation issues.
Dimensions for Replacement Matching
Accurate dimensions are important when sourcing a replacement trailer leaf spring. The FWN-024 features a 1.75-inch leaf width and a listed overall length of 32 inches, providing key reference points for buyers comparing replacement requirements.
The free-open specification is listed at 4 1/4 inches, which should be considered together with the existing suspension geometry rather than used as the only selection criterion. Buyers should verify the complete spring dimensions and mounting configuration against their original component before placing an order.
Replacement Applications for Utility Trailers
A properly matched utility trailer leaf spring can help restore suspension support when an existing spring has become damaged, deformed, or worn. Before replacing a spring, inspect the entire suspension assembly for signs of fatigue, corrosion, damaged bushings, loose hardware, or uneven spring height.
For fleet operators, trailer manufacturers, distributors, and replacement-parts buyers, confirming the load rating and physical configuration is particularly important. The FWN-024 offers a defined 4-leaf, 1100 lb configuration for buyers seeking a compatible trailer suspension replacement.
OEM and Bulk Trailer Leaf Spring Supply
The FWN-024 is also suited to wholesale and OEM purchasing requirements where consistent specifications are needed across multiple trailer units. With an MOQ of 100 units, it is positioned for bulk procurement rather than individual consumer replacement.
FWN Trailer supports trailer suspension component manufacturing for customers requiring specific configurations and replacement solutions. Buyers can use the listed specifications as a starting point when checking compatibility with their trailer suspension assembly and can provide additional technical requirements when a particular application requires further confirmation.
Choosing the Right Trailer Leaf Spring
Choosing a replacement leaf spring involves more than matching the number of leaves. Load capacity, spring length, leaf width, end configuration, bushing arrangement, and suspension geometry should all be considered together. An apparently similar spring may not provide the correct fit or load characteristics if one of these factors differs.
For the FWN-024, the key selection criteria include its 4-leaf construction, 1100 lb capacity, 32-inch length, 1.75-inch width, radius-end slipper design, and PE-226 bushing. Confirming these details against the original spring before purchase helps buyers select a replacement with greater confidence.
Product Summary
The FWN-024 4 Leaf 1100Lb Trailer Leaf Spring provides a defined suspension replacement option for compatible utility trailer applications. Its 4-leaf construction, 1100 lb capacity, 32-inch length, 1.75-inch width, and radius-end slipper configuration make it suitable for buyers looking for a clearly specified trailer suspension component.
For bulk replacement, trailer manufacturing, or distribution requirements, the product can be evaluated according to the complete suspension configuration rather than capacity alone. Careful dimensional and mounting checks remain essential to achieving proper fitment and dependable trailer suspension performance.
