Improve drivetrain behaviour on older XB series cars with the XRAY 364091 eccentric insert in aluminum. Tailored for narrow motor bulkheads, it allows small but effective motor shifts to refine gear contact and vehicle handling. The aluminum construction is built to tolerate regular track use while remaining light and precise.
A sensible upgrade for hobbyists running classic XB chassis, this insert helps with accurate motor placement and contributes to steadier on-track performance.
