Yokomo YS-4L-8 R. Shock Body — Rear Damper Body for Off-Road R/C  [YS-4L-8]

Rear damper body and installation notes

The Yokomo YS-4L-8 R. Shock Body is an R/C-scale replacement component intended for rear damper assemblies on off-road models. It serves as the outer housing that locates internal damper components and contributes to repeatable piston travel and seal positioning.

Use this part when replacing a worn or damaged shock body or when swapping components during suspension setup. Removal and installation follow common damper service steps: drain oil, disassemble cap and shaft, transfer internal components carefully, and verify seal seating before refilling oil. Treat this strictly as an R/C model component and avoid implying any real vehicle application.

For tuning, the shock body affects how easily you can service the unit and inspect piston travel; it does not change piston size or valving by itself but supports consistent assembly during tuning cycles. When reassembling, check for burrs, proper O-ring seating, and correct shaft clearance to reduce leakage and ensure consistent damping.
