Hobbyists and racers can refine damping characteristics using the XRAY 368091 Rubber Shock Absorber Shim Set. Designed to seat within the XB4 aluminium shock caps, the four shims improve shock compliance and support accurate setup adjustments.
The chosen rubber compound resists permanent deformation and handles repeated compressions, helping shocks retain consistent behaviour over many runs. A secure fit in the XB4 aluminium caps reduces unwanted movement and preserves tuning accuracy.
These shims are dimensioned for the XB4 chassis so they install cleanly into the aluminium caps. Use the set to tweak mid stroke feel, sharpen turn-in, or reduce chatter on bumpy surfaces.
