Restore control, stability, and load distribution to your mid-weight trailer suspension with this heavy-duty 4-leaf open-eye slipper spring. Built specifically to handle harsh road conditions and demanding payloads, this spring flexing unit soaks up severe road vibration, keeps your chassis level, and minimizes frame fatigue over long hauls.
 
Crafted from solid 1-3/4" wide high-grade steel with 3/8"-thick individual leaves, it delivers high resistance against premature sagging and mechanical wear. The front eye comes pre-fitted with a low-friction 9/16" ID nylon bushing for effortless pivot movement and quiet operation, while the open-eye slipper end seamlessly glides into standard rear hangers or equalizer systems.
 
Key Benefits
Smooth Load Cushioning: 4-leaf stack progressively absorbs severe shocks and washboard ripples, protecting cargo from damaging road impact.

Pro-Tip for Installation: Always replace leaf springs in matched pairs. Swapping out only one side can cause uneven height, imbalanced weight distribution, and accelerated tire wear across your axle assembly.
