Complete parts set for assembling 2 big-bore REAR shock absorbers for XB8. Includes soft rubber folding boots. The XB8 big-bore, long-stroke shocks have a special construction that gives ultimate reliability and performance. These new shocks have had all parts fully redesigned and adjusted to take advantage of the big-bore design. The oversized big-bore shocks feature 18.5mm outer diameter shock bodies, externally threaded with an adjustable collar for quick & easy spring preload adjustment. The shock bodies are hardcoated in a titanium color and feature a 1-piece aluminum shock cap.
Ultra-precise shock pistons feature 6-, 8- and 10-hole options. The longer shock shafts and shock collar combine to give increased downtravel. Ultra-fine shock protective rubbers give superior sealing against dirt. The large 16mm inner diameter shock bodies ensure proper and consistent shock oil flow through the perfectly-round pistons while they travel inside the smoothly-finished interior. The result is more consistent damping characteristics. The big-bore pistons are molded from tough, durable Delrin® material to provide smoother action and durability. The precision molding production process ensures perfect roundness of the pistons after production, so that they move smoothly inside the shock bodies for identical action in all shocks. The specially-formulated soft-rubber shock membrane ensures equal damping characteristics from the beginning of the race to the end, even after extreme operation. The lower shock assembly ensures that the shock rod will move very freely inside the shock body, while minimizing oil leakage and keeping dirt out. Two shock O-rings manufactured from a superior silicone compound to allow ultra-free movement of the shock rod while still maintaining a tight seal are installed in the lower part of the shock body and are secured with composite shims. The entire lower shock assembly is secured with the lower aluminum shock cap which makes assembly/disassembly very quick and easy. Thick and robust shock shafts will handle any abusive racing conditions and big jumps. The 3.5mm thick shock shafts are precisely machined from special high-tensile steel and afterwards are ground for a super-smooth finish to ensure smooth movement of the shock shafts in the shock bodies. Springs NOT included.
