XRAY T4 3-Hole 1.3MM Composite Pistons for Shock Tuning - Arrowmax AM-T4-308037B3  [AM-T4-308037B3]

Aftermarket 3-Hole Pistons for XRAY T4

Arrowmax AM-T4-308037B3 composite pistons are supplied as a set of 4 and are intended for XRAY T4 damper assemblies. The 3-hole, 1.3MM design alters oil flow through the piston to change damping characteristics without needing different damper bodies or shafts.

Use these pistons when a simple damping change is required during setup or routine maintenance. They serve as direct replacement pistons in T4 shock bodies that accept 3-hole inserts, and the composite material is chosen for resistance to wear over repeated rebuilds.

Installation is standard procedure: disassemble the damper, swap in the piston with the correct driveshaft orientation, check seals and shim stack, then reassemble and confirm consistent travel and no leakage. For tuning, combine the 1.3MM 3-hole piston with suitable shock oil and spring rates to fine tune rebound and compression.
