Toyota Tundra 12-Inch Square Rear Lift U-Bolts

Our Toyota Tundra 12-inch square rear lift u-bolts are designed for maximum u-bolt clamp force to securely clamp leaf spring and mating components together. With the clamping of the spring by our u-bolts, spring flex will be eliminated, and vehicle stock specifications will be restored. Our u-bolts will provide desired spring stiffness, allowing the spring to absorb shock when it is applied to your suspension when driving over rough terrain. The u-bolts are constructed from top-quality steel with grade 8 hardware that has been tested for strength and durability.

All components in this kit are manufactured in America by American Automotive. Kit contains: 4 steel u-bolts with grade 8 hardware (washers and nuts), installation instructions, and a manufacturer’s lifetime replacement warranty. Allowances need to be made for all overloads and aftermarket leafs. 5-inch thread can be cut down to fit many applications.
