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 2655 arms are strong yet lightweight and feature a removable lower mounting system to permit spring 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 standard height 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 4035 and 4067 as well as many other factory fit sway bars.
