Product Description

The Superlift 1275 Radius Arm Bracket Kit provides essential caster correction for lifted 1966-1979 Ford Bronco and F-Series 4WD trucks. When a solid front axle vehicle is lifted, the radius arms become angled because the axle end moves downward while the frame mount remains in its factory position, resulting in reduced caster angle that causes poor steering response and instability. This bracket kit lowers the factory frame mounting point by 2.75 inches, restoring proper radius arm geometry and maintaining correct caster alignment. Backed by Superlift's limited lifetime warranty.
