CNC-machined alu front shock body for XB8 Zero Rebound Shocks, made from premium lightweight 7075 T6 aluminum. The special design of the shock body and upper cap allows the installation of a ribbed shock membrane on the top of the shock body instead of traditional installation into the upper cap. The installation of the ribbed membrane on the shock body allows excess oil to leak out, and along with a shock cap vent hole and adjusting screw allows the adjustment of the amount of air (rebound) until the desired zero rebound is achieved. The oversized big-bore shocks feature 18.5mm O.D. shock bodies, externally threaded with an adjustable collar for quick & easy spring preload adjustment. The shock bodies are coated in a titanium color. Set of 2.
