Yokomo R12-37P X shock maintenance kit for R12/GT chassis  [R12-37P]

Shock service parts for R12/GT

This is a maintenance kit for the X shock used on Yokomo R12 and GT series 1/10 touring car models. The kit is intended as a service-level accessory to support routine upkeep and repair of shock assemblies on the listed chassis, keeping them at consistent damping performance for track or practice sessions.

Use this kit when rebuilding shocks after extended running or exposure to dust and track debris. Typical workflow is to remove the shock from the car, disassemble the X shock assembly, replace worn service components, then reassemble and check for smooth shaft movement and consistent damping feel. This product is an RC-scale accessory and is intended only for model maintenance.

As a tuning aid, fresh service parts help restore repeatability between runs, making baseline setup and fine tuning of spring rates and damper settings more reliable during setup changes.
