For anyone tuning an XB4, the XRAY 368042 Composite Shock Bushing & Shim Set built for the XB4 aluminum shock cap is designed to improve component life and give more predictable mounting behaviour. It supports accurate tuning of the suspension interface.
Both bushings and shims are produced in a tough composite that copes with repeated on track use. This durability helps maintain steady shock movement and reduces variation between runs.
The kit includes two bushings and two shims so you can make small, measurable changes to shock spacing. These micro adjustments help you tune for either improved stability or crisper response.
Use the components when servicing worn parts or when refining your setup before an event. Swapping to fresh bushings and shims helps keep handling consistent and dependable.
