Our universal 12-inch square rear lift u-bolts are engineered to accurately fit matching components and provide the force required to clamp the leaf spring to the rear axel assembly. Designed to eliminate spring flexing and restore stock specifications, such as ride height and handling characteristics as specified by the vehicle. Properly installing our u-bolts will also help reduce stress concentration (pressure is evenly distributed), prevent premature spring failure, and allow your spring to absorb shock when it is applied to your suspension.
Sold as a set of 4 steel u-bolts with all hardware needed to install, installation instructions and a manufacturer’s lifetime replacement warranty from American Automotive. All contents are American made. Allowances need to be made for all overloads and aftermarket leafs. 5-inch thread can be cut down to fit many applications.
