3057-1 - 1978-1988 GM G-Body, 1982-2003 S10/S15 Front Lower A-arms, C/O Only

UMI’s 3057-1 lower a-arms arms feature a relocated ball joint cup which offers 10 degrees caster when used with our P/N 3056 upper arm while keeping the spindle pin centered. The 3/4” taller Howe ball joint works to optimize the roll center, lower the center of gravity and lowers the ride height ½”. The double shear shock mount is removable which permits spring and shock changes at the track in minutes without disconnecting the ball joints. An aluminum steering stop is adjustable and limits steering lock to prevent tire and wheel damage. UMI designed Delrin bushings help the 3057-1 travel smoothly for bind-free operation whether running street, strip, road race or auto-x. Also included is a double shear sway bar mounting system which accepts UMI sway bars and many other manufacturers stock location aftermarket units. Available in UMI red or black powder coat. 100% designed, manufactured and raced with pride in the USA. Battle tested on the iconic UMI Green Machine
