Yokomo YOKRP-084BK Ultra Off-Road Rear Spring (Black) Racing Performer  [YOKRP-084BK]

Ultra off-road rear spring

This Yokomo rear spring is an RC-scale replacement part intended for off-road suspension use. It is supplied as a single-purpose coil intended to mount on compatible rear shock assemblies, serving the role of basic springing in rear suspension setups without implying model-specific fitment.

Installation is straightforward for common coil-over shock designs: remove the shock from the chassis if needed, relieve preload, slide the spring over the shock shaft and seat it on the spring perch, then reapply preload and reassemble. Verify that the spring length and internal diameter match your shock’s retainer and shaft before final fitment.

In tuning, rear springs influence rear-end balance, traction and rebound response. Use these springs in combination with appropriate shock oil viscosity, preload adjustment and shock travel limits to reach the desired handling. Make incremental changes and test on representative surfaces to evaluate how spring rate and preload affect rotation and traction.
