Complete set of Zero Rebound back Shock Absorbers for XB8. Zero Rebound Shocks may be set to permit less rebound than standard shock absorbers, decreasing responsiveness and improving bump consumption on bumpy songs. The special design of this surprise human body and top limit enables the installation of a ribbed surprise membrane on the top regarding the surprise human anatomy rather than conventional installation to the top cap. Installing the ribbed membrane layer in the shock human body allows extra oil to leak down, and alongside a shock cap vent gap and adjusting screw enables the modification regarding the number of air (rebound) before the desired zero rebound is achieved. The oversized big-bore shocks feature 18.5mm O.D. shock systems, externally threaded with a variable collar for fast & effortless spring preload modification. The surprise bodies are coated in a titanium color, and have a 1-piece aluminum surprise cap with vent opening. The specially-formulated plastic material of this surprise membrane ensures equal damping characteristics right from the start of the race on end, even after extreme procedure. The low surprise set up helps to ensure that the surprise rod will move really easily inside the surprise body, while minimizing oil leakage and maintaining dust out. Two surprise O-rings made of a superior silicone substance allowing ultra-free motion regarding the surprise rod while still maintaining a good seal are installed in lower the main shock human anatomy and tend to be guaranteed with composite shims. The entire reduced surprise construction is guaranteed because of the lower aluminum surprise cap making assembly/disassembly extremely swift and simple. Thick, robust surprise shafts handle all abusive race conditions and big jumps. The 3.5mm dense shock shafts are precisely machined from special high-tensile steel, and a while later are ground to a super-smooth finish to make sure smooth movement. Includes complete set of pistons and reduced rubber boots. Springs are NOT included.
