Solid Rear Suspension Mount for XRAY XB4 Stability

Responsive Geometry Tuning with I.S.S.

Built around Integrated Suspension Settings (I.S.S.), this holder makes suspension tuning faster and more predictable. Ported from the XB8 into the 1/10 XB4 range, the design uses eccentric bushings and shim stacks so you can dial in balance and rotation for varied track conditions.

For racers and serious hobbyists, the XRAY 363311 provides a durable, adjustable rear mount that helps fine-tune handling on demanding high-grip surfaces.
