XRAY 358021-G Keyed Ball Joint and Collar Set - Graphite  [XR-358021-G]

Durable graphite composite shock parts

This set contains composite molded components designed for two shock absorbers, including spring lower collars and keyed ball joints. The lower ball joint is fitted with a lock extension that seats into the lower collar to reduce the risk of the collar separating from the spring after an impact.

Manufactured from a graphite composite mixture, the parts are intended for RC-scale suspension use where durability and consistent movement matter. The material choice and molding keep the joints running freely with minimal binding, including in dusty conditions that commonly affect small-scale suspension links.

In practical setup and tuning, these components act to improve shock retention and reduce maintenance interruptions caused by collar disconnection. They are most relevant when you need reliable lower ball joint retention and predictable travel while adjusting damping or spring pre-load on GTX-series setups.
