The XB2 shock absorbers feature eccentric reduced mounting pivot ball that changes the angle for the shocks whenever installed into the arm. Shock expansion is limited making use of composite shims underneath the pistons. Maximum compression is bound utilizing composite shims underneath the surprise collar. The shock absorber is universal for both Dirt and Carpet edition. This set includes composite bushings for aluminum surprise caps. Do not use these composite bushings for composite surprise limit from this set. Note that pivot balls for lower ball joints is employed from your own kit or purchase separately.
