XRAY T4 Composite Pistons 3 Hole 1.3MM by Arrowmax AM-T4-308037B3  [AM-T4-308037B3]

Composite 3-Hole Pistons for XRAY T4

These Arrowmax composite pistons are supplied as a set of 4 pcs and are intended for use in XRAY T4 damper assemblies. The 3-hole, 1.3MM design affects oil flow through the piston for damping adjustment without changing damper bodies or shafts.

Use these pistons when you need a simple change to damping characteristics during setup or maintenance. They work as direct replacement pistons inside compatible T4 shock bodies where the piston geometry accepts 3-hole style inserts. The composite material is chosen for wear resistance in repeated assembly and teardown situations.

Installation is conventional: disassemble the damper, swap the piston with the matching driveshaft orientation, inspect seals and shims, reassemble and check for consistent stroke and leak-free operation. For tuning, pair the 1.3MM 3-hole piston with appropriate shock oil and spring rates to reach the desired rebound and compression balance.
