This rear suspension link set is a direct replacement part designed for the Yokomo R12/GT family, intended to restore or adjust rear link geometry on 1/12 scale electric on-road RC cars. The R12-21L covers the supported chassis listed below and serves as the rear linkage between hub carriers and the chassis mount points.
Compatibility is explicit: YR-R12C3, YR-R12C31, YRF-001RF, YRF-001W. The parts replace the stock rear links without requiring modification to the chassis, letting you return the rear toe and roll-center geometry to factory alignment or apply small tuning changes by swapping link lengths or positions when applicable.
Installation notes: inspect mounting points and fasteners for wear before fitting, fit the links into the rear link mounts and secure to original mounting hardware, then verify symmetrical alignment and free movement through full suspension travel. For tuning, change link placement or pairing with other rear suspension components to alter handling balance in small, incremental steps.
