When you’re working with an 8,000-lb axle, you need hardware that won’t flex or loosen over time. This kit uses sturdy 9/16"-18 diameter U-bolts that clamp your 3-1/2" round axle firmly to the leaf springs. Tightened to the proper 65-95 ft-lb torque range, they deliver the strength and grip needed to keep your suspension secure mile after mile.
Getting everything cinched up right is simple with the included 8" long U-bolts and matching plates. The plates fit both 1-3/4" and 2" wide springs, giving you a clean fit without extra parts or guesswork. Each kit includes four U-bolts, two plates, and eight hex nuts so you can mount both sides of one axle in one go.
This set is made specifically to mount a 3-1/2" diameter, typical 8,000-lb round axle to your trailer’s leaf springs. With all the key hardware included, it provides a strong and even clamp that keeps your axle seated tight under load. Spring seats are required for mounting and sold separately, letting you match the exact style your setup needs.
A strong axle connection means better handling and fewer maintenance worries. The solid steel U-bolts and heavy plates resist stretching and wear, keeping your suspension geometry locked in. It’s a simple, tough setup that gives you confidence your axle will stay right where it belongs.
