This Arrowmax aluminium shock body is offered as a direct replacement option for XRAY T4 kits where pilots prefer a metal sleeve over the original polymer part. The unit emphasises accurate external geometry and a harder surface to protect the shock shaft and seal seating through many runs.
Fitting is familiar to anyone who services T4 coilover shocks: take the shock apart, swap the original body for the aluminium piece, and rebuild using your current internals and oil. No advanced tooling is needed, but be careful to keep seals correctly located during reassembly.
In setup the aluminium body alters the contact between damper internals and the outer sleeve by providing a steady, wear-resistant surface. This helps keep valving feel consistent and limits small dimensional drift from plastic wear, enabling you to fine-tune spring choices, oil viscosity, and piston options.
Fits XRAY T4 shock assemblies that accept the standard T4-series shock body dimensions and mounting pattern.
