R12 Rear Shock Cylinder (Long) - Yokomo YOKR12-18CR  [YOKR12-18CR]

Long rear shock cylinder for R12 dampers

This long rear shock cylinder suits R12-design rear shock assemblies on 1/12 scale RC cars. It offers a longer cylinder body that alters available travel and increases internal oil volume compared with standard-length cylinders, and is intended for use when tuning the suspension or replacing worn damper components.

Compatibility is limited to R12-configured rear dampers as indicated by the product designation. When fitting this cylinder, confirm piston, seal and shaft clearance match the existing rear damper stack, and inspect O-rings for proper seating to avoid leaks. Use appropriate shock oil and piston combinations for the target damping response rather than changing settings arbitrarily.

Setup notes: the extended cylinder body increases oil capacity and can change travel characteristics, which helps when adjusting rear damping balance, rebound behavior and chassis attitude during track setup or practice sessions. Make incremental changes and document results so they can be repeated.
