Yokomo Y4-S4C Aluminum Shock O-Ring Cap and Adjust Nut Set  [Y4-S4C]

Track-Ready Yokomo Y4-S4C Shock Components

For drivers refining setup, the Yokomo Y4-S4C Aluminum O-Ring Cap and Adjust Nut Set is a straightforward upgrade to sharpen shock feel. Made for big bore shocks, these aluminium parts are light yet tough to stand up to repeated use on the circuit.

Improve Damping Control

The package supplies two O-ring caps, two adjust nuts and two cap nuts so you can rebuild a pair of shocks with factory-style hardware. The laser-etched Yokomo logo on the cap nuts indicates precise CNC work and consistent part sizing.

Compatible Shock Types

Designed to mate with super low friction aluminum big bore shocks, the set is ideal for hobbyists tuning suspension for steadier travel and cleaner rebound. It suits both club competition and aggressive hobby driving where consistent damping matters.
