The big bore 13.2mm shocks parts are redesigned for general maneuvering and gratification improvements. The top bore shocks improve landings and provide better control of surface unevenness and bumps to boost traction. There are two different depth pistons (2.0 and 2.5mm). The super-efficient pre-oiled X-rings make certain smooth procedure and give a wide berth to dirt in the shock construction. The XB2 surprise absorbers feature eccentric paid off mounting pivot ball that changes the angle for the shocks whenever installed into the supply. Shock expansion is limited using composite shims underneath the pistons. Optimum compression is bound using composite shims under 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 shock limit with this set. Observe that pivot balls for reduced ball bones is employed from your own kit or purchase individually. Confirm the X-rings are preoiled before installation.
