The Yokomo YR-22R is supplied as a replacement right-side rear roll shock mount for 1/10 scale formula chassis, matched to the YR-10F. It is designed to sit within the rear roll damper layout and serve RC model applications.
Functionally the YR-22R anchors the roll shock to the rear suspension pick-up points and plays a role in the chassis' roll behavior during cornering. As part of a setup routine it shifts roll force distribution between the rear shock and any anti-roll linkages, so it can be used to fine-tune roll balance front-to-rear.
Fitment guidance: this mount corresponds to the YR-10F rear attachment locations and uses the existing chassis rear mount holes and fastening hardware. Verify correct right-side orientation on fitment, ensure alignment with the shock shaft and suspension links, and check full-travel movement before operating the model.
Setup advice: view this mount as integrated into the roll-control system rather than an isolated stiffness change. Small stepwise changes to shocks, sway setup and ride height will show how handling is affected. Test alterations on a suitable surface to confirm handling outcomes.
