The Yokomo YR-22R is a direct replacement right-side rear roll shock mount made for 1/10 scale formula chassis, specifically the YR-10F. It fits the rear roll damper arrangement and is designed for RC model use.
Functionally, this mount secures the roll shock to the rear suspension pick-up points and influences chassis roll behavior during cornering. Used in a tuning program, it alters how roll forces are shared between the rear shock and any anti-roll linkages, making it useful when adjusting roll balance between front and rear.
Fitment notes: the YR-22R aligns with the YR-10F rear mounting positions and is fitted using the chassis' existing rear mount holes and hardware. Confirm the correct right-side orientation during installation, check alignment with the shock shaft and suspension links, and verify free movement through the full suspension travel before running.
Tuning advice: consider this mount as part of the roll control system rather than a standalone stiffness change. Small, incremental changes to shocks, sway setup and ride height will reveal how the mount alters oversteer or understeer tendencies. Always validate setup changes on a representative surface before competitive use.
