U-Bolt:
When U-bolts are tightened to secure the leaf pack in the vehicle from factory, the metal is stretched as a normal part of this process. It is important that U-bolts be replaced when a suspension system is changed, as a stretched U-bolt has lost its integral strength. The U-bolt will appear tight when re-used, but in fact it isn’t, this puts undue pressure on the centre bolts in the springs, causing them to move or snap which in turn allows the diff to move and the leaves to spread. Tough Dog U-bolts are manufactured using high tensile steel & are designed with the correct length of thread for larger, heavy duty leaf spring packs.
Urethane Bushes:
Leaf spring based suspension set ups generally have a bias leaning towards load carrying capability over ride quality. The design and composition of the shackle hanger and bushing material can make all the difference to your ride quality. This assembly is the spring’s first part to move in response to uneven terrain and bumps in the road. Tough Dog urethane is stronger than rubber components and has greater longevity and resistance to deterioration from chemical exposure. Urethane bushes respond well to greasing during operation and are created to retain flexibility for ride comfort. When required, steel tubes in the centre of the bush are hardened and chemically treated to resist corrosion. All of this will keep your leaf sprung vehicle in positive contact with the road surface and give you better tyre and suspension component life. Replacement urethane bushes are available for all Tough Dog leaf springs as well as for a range of other suspension bushing locations in vehicles. Tough Dog also have a range of coil spring spacers to assist in levelling and trimming live axle coil vehicles. Poured as a single piece urethane, Tough Dog spring spacers are available in various heights, depending on the vehicle and application.
