Bumpy and uneven surfaces can make any trip feel harsh. This 4-Leaf Slipper Spring flexes to resist shock and smooth out the ride so the trailer tracks level and steady. Each of the four 3/8" thick steel leaves shares the load, cutting down on bounce and wear while keeping everything stable mile after mile.
When you’re carrying weight, you want the suspension to do its share of the work. This spring provides a solid attachment point for a 4,000-lb axle, with a 2,000-lb spring capacity per side. The steel construction holds strong under load while still allowing enough flex to protect the frame and cargo from road shock.
Keeping your axle in line starts with proper mounting. The front eye of this spring fits a 9/16" inner-diameter nylon bushing and attaches cleanly to a front hanger. The hook-style slipper end slides into the rear hanger or an equalizer for multi-axle setups, giving a simple, reliable suspension connection that keeps things centered and aligned.
Whether you’re replacing worn hardware or building from scratch, dimensions matter. This spring measures 26-5/8" from the center of the eye to the end of the hook and is 2" wide—ideal specs for pairing with standard hangers or equalizers. Replacing springs in pairs ensures even height and smooth suspension performance across both sides.
Over time, metal-on-metal contact can cause noise and wear. The included nylon bushing helps prevent that by reducing friction in the mounting point. It keeps motion smooth through each flex of the spring, cutting down maintenance while extending the life of the suspension system.
