The XRAY 368024 Composite Spring Collar Set is made for XB4 chassis and includes -2mm and -4mm collars to tweak ride height precisely. These parts are intended for use with big bore shocks and help you adapt suspension behaviour to different track conditions.
Adding these composite collars expands your tuning range so you can fine tune chassis roll and weight transfer. The built in cleaning holes make it straightforward to remove grit and keep the collars functioning well session after session.
Designed to sit on larger shock bodies, these collars match the dimensional needs of big bore dampers commonly used in high performance builds. They help the suspension remain predictable when you demand tighter control from the shocks.
