Overview
UMI Performance Corner Max Front Lower Race A-Arms
UMI Corner Max front lower A-arms are designed from the ground up to be the best performing stock mount A-arm upgrade on the market. Strong yet lightweight, they feature a removable lower mounting system to permit spring or shock changes at the track without separating the ball joints. The ball joint cup is moved forward the proper amount to add up to 4 degrees caster potential—and is loaded with either high-quality Howe standard height or premium Howe +1/2 or +3/4 in. tall ball joints. The double shear coilover mount accepts race industry standard 1/2 in. rod end shocks, and comes with spacers for all popular models. Also included is a double shear sway bar mount and corresponding end link. Order the pair recommended for your vehicle.
Product features:
* Camber curve and roll center height are improved to yield incredible front-end grip
* Coilover-only design saves weight over spring bucket versions
* A-arms enhance steering feel and straight line stability
* 1.500 in. DOM steel tubing construction
* Includes Delrin® bushings for smooth suspension travel and decreased deflection
