The Arrowmax AM-T4-308364 is a hardened shock shaft designed for use with XRAY T4 chassis as a replacement or upgrade part. It aims to extend service life and deliver consistent suspension behaviour without changing core shock geometry or damping components.
Made from spring steel with a hardened surface, the shaft cuts down wear at seal and piston interfaces to preserve smooth suspension travel through multiple outings. This shaft fits T4-style shock assemblies; confirm the shaft end and your shock retainers are compatible before installation.
Setup notes: swap shafts one at a time to keep oil and spring settings comparable, inspect internal shock parts when changing shafts, and bench-test rebound and compression to verify the response you want before hitting the track.
