Rough highways and uneven ground can pound your trailer, but this 7-leaf slipper spring keeps things steady. Its stacked steel leaves flex to absorb shock and keep the trailer level over bumps. Rated for 8,000-lb axles with a 4,000-lb spring capacity, it helps reduce bounce, sway, and the wear that long hauls can cause on suspension components. The spring’s 26-5/8" unloaded length and 2" width deliver solid support for heavy loads while maintaining a smooth towing feel.
Heavy loads and long miles demand a spring that won’t sag or crack. This slipper spring is built from sturdy steel to handle tough conditions without losing shape. The pre-installed nylon bushing in the 9/16" eye helps the spring pivot smoothly on the hanger bolt, cutting down friction and noise. Together, they create a system that’s tough enough for high-capacity use and still moves quietly and cleanly.
The hooked slipper end slides cleanly into the rear hanger or equalizer for a secure connection that keeps everything aligned. The front eye mounts to a welded hanger on the frame, creating a strong, simple suspension link that’s easy to maintain. With precise measurements—like 11-1/2" from the center of the eye to the spring seat and 26-5/8" total length—the geometry stays true so the axle tracks straight mile after mile.
Whether you’re setting up a tandem or triple-axle system, this spring gives you the flexibility to match your build. It pairs with 2" slipper spring hanger kits using 12" equalizers for smooth articulation between axles. That means you can confidently carry heavy loads while keeping consistent ground contact and even tire wear across the setup.
