The Yokomo YR-22R serves as a replacement right-side rear roll shock mount intended for 1/10 scale formula chassis and specifically matched to the YR-10F. It interfaces with the rear roll damper arrangement on the chassis and is intended for RC model applications.
In operation the component secures the roll shock at the rear suspension pick-up points and contributes to how the chassis rolls through corners. When integrated into a tuning program it changes the distribution of roll forces between the rear shock and anti-roll linkages, so it is a practical option when rebalancing roll between front and rear.
Fit notes: the YR-22R lines up with the YR-10F rear mounting holes and installs with the chassis' existing hardware. Ensure correct right-side orientation at fitment, check shock shaft and link alignment, and confirm full suspension travel is free before putting the model on track.
Tuning tip: treat this mount as one element of the roll-control system rather than a single stiffness modifier. Make modest adjustments to shocks, sway settings and ride height to observe the mount's influence on handling. Always trial changes in a representative environment to verify results.
