Tough Dog U-Bolts

When U-bolts are tightened to secure the leaf pack in a vehicle from the factory, the metal stretches as part of this normal process. Over time, this stretch reduces the bolt’s integral strength, making replacement essential when modifying a suspension system.

A **stretched U-bolt** may appear tight when reused, but it lacks proper tension, placing undue pressure on the **centre bolts** in the springs. This can cause them to move or snap, leading to **diff movement** and **leaf spring separation**, compromising vehicle safety and stability.

**Tough Dog U-bolts** are manufactured using **high tensile steel**, ensuring optimal strength and durability. They are specifically designed with the **correct thread length** for **larger, heavy-duty leaf spring packs**, providing secure installation and improved performance for off-road applications.
