Upgrade or replace your trailer suspension with this 25-1/4" Double-Eye Trailer Leaf Spring, designed for durability, smooth ride quality, and reliable load support. Built from high-quality spring steel, this leaf spring is engineered to handle demanding trailer applications while maintaining consistent suspension performance.

This spring features a double-eye design, one of the most common suspension setups used on cargo trailers and utility trailers. Double-eye springs allow the suspension to flex through shackle links and equalizers, creating a smoother ride and improved load distribution compared to slipper-style springs.

The spring measures 25-1/4" from center eye to center eye and is constructed with four tightly banded leaves, providing a 3,000 lb capacity per spring (6,000 lb per axle) when used in a pair. Each spring includes 9/16" nylon bushings pre-installed in both eyes, allowing for straightforward installation and reduced friction.

This leaf spring is commonly used on Dexter 6,000 lb trailer axles, making it a dependable replacement for worn or flattened springs.
