Complete pair of Zero Rebound Rear Shock Absorbers for XB8. Zero Rebound Shocks could be set to permit less rebound than standard surprise absorbers, decreasing responsiveness and increasing bump absorption on bumpy tracks. The unique design of shock body and upper limit permits the installation of a ribbed surprise membrane layer on top associated with shock human anatomy in the place of traditional installation in to the top cap. Installing the ribbed membrane layer on the shock human body enables extra oil to leak out, and alongside a shock limit vent hole and adjusting screw allows the adjustment of the amount of atmosphere (rebound) until the desired zero rebound is accomplished. The oversized big-bore shocks feature 18.5mm O.D. shock bodies, externally threaded with a variable collar for quick & effortless spring preload adjustment. The surprise systems are covered in a titanium color, and have a 1-piece aluminum shock limit with vent hole. The specially-formulated plastic material of this shock membrane guarantees equal damping faculties right from the start associated with the competition towards end, even with extreme operation. The low surprise assembly ensures that the surprise pole will move really easily within the shock body, while minimizing oil leakage and maintaining dirt out. Two shock O-rings manufactured from a superior silicone element to permit ultra-free movement of surprise pole while still keeping a taut seal are installed within the reduced area of the shock body and generally are guaranteed with composite shims. The whole lower surprise construction is secured aided by the reduced aluminum surprise limit which makes assembly/disassembly very quick and easy. Thick, robust surprise shafts handle all abusive race conditions and big jumps. The 3.5mm dense shock shafts are precisely machined from unique high-tensile steel, and after ward are ground to a super-smooth finish to make certain smooth motion. Includes complete group of pistons and reduced rubber shoes. Springs are NOT included.
