Reliable and Long-Lasting

Installed six months ago on a daily-use utility trailer. Still holds its arch perfectly. No broken leaves or bushing wear. The nylon inserts haven’t cracked either.

Great for Tandem Axle Builds

Bought six sets (3 per axle) for a commercial flatbed. Installed with standard slipper hangers. Load transfer is even, and the trailer tracks straight—no swaying.

Minor Noise at Full Compression

Under extreme load, there’s a slight creak between leaves. A little grease between them fixed it. Otherwise, performance is excellent and ride is much smoother.

Slight Stiffness at First

Use them for a few hundred miles—they’ll break in. Initially felt rigid, but now ride smoothly under load. Steel quality feels high—no cracks or warping after months of use.

Worth Buying in Bulk for Fleet Work

Bought eight for a fleet trailer rebuild. The 30% discount made it a no-brainer. All were consistent in quality and fit. Now all trailers ride the same—no more weak corners.
