Complete parts set for assembling 2 big-bore front shock absorbers for XB808 with soft rubber folding shock boots. Includes front silver springs (C = 0.75). The oversized big-bore shocks feature 18.5mm O.D. shock bodies, externally threaded with an adjustable collar for downstops adjustment. The shock bodies are hardcoated and feature a new 1-piece aluminum shock cap.
The large 15.3mm I.D. shock bodies ensure proper and consistent shock oil flow through the perfectly-round pistons, which move very precisely inside the smoothly-finished interior of the shock body. The result is more consistent damping characteristics of the shocks. The new big-bore pistons are manufactured from well-proven specially-formulated composite material to provide smoother action and durability. The well-proven molding production process is used to ensure perfect roundness of the pistons after production, so that the pistons move perfectly inside the shock bodies for identical shock action in all four shocks.
New shock membranes are now wider to fit the new big-bore shocks. The material has been also improved to guarantee the same damping characteristics from the beginning of the race to the end, even after excessive loads. The lower shock assembly ensures that the shock rod will move very freely inside the shock body while minimizing oil leakage and keeping dirt away. 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 a new lower aluminum shock cap which makes assembly/disassembly quick & easy. The aluminum lower cap features a securing groove for the external protective folding rubber shock boot. The shock shafts are thick and robust to ensure they can 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 surface to ensure super-free and smooth movement. Note: The XB9 shock absorbers #358104 (front) and #358204 (rear) are a direct replacement for the 808 shock absorbers #358103 (front) and #358203 (rear). When using XB9 shock absorbers on the 808 only the lower shock tower positions should be used or it is suggested to use also the XB9 shock tower #352094 (front) and #353094 (rear).
