UMI’s Corner Max line of race a-arms are designed from the ground up to be the best performing stock mount a-arm upgrade on the market. The P/N 4062-1 arms are strong yet lightweight and 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 high quality Howe +3/4” tall ball joints. The double shear coilover mount accepts race industry standard ½” rod end shocks and comes with spacers for all popular models. Also included is a double shear sway bar mount and corresponding end link. The end link fits UMI P/N 4035 and 4067 as well as many other factory fit sway bars.
