XRAY T4 Composite 3-Hole 1.2mm Tuning Pistons (4 pcs) by Arrowmax AM-T4-308037B2  [AM-T4-308037B2]

This pack contains four composite pistons made for XRAY T4 damper bodies, each featuring a three-port layout and a 1.2mm main hole, supplied as 4 pcs. They provide an easy way to refine shock flow without modifying damper bodies or shafts.

Fitting these pistons alters low and mid-speed oil flow by changing bleed area, helping you tailor initial feel and mid-stroke control. The composite material holds its shape under normal hobby use and the 3-hole design balances rebound and compression behaviour for T4 style valving.

Installation is simple: remove the damper shaft and piston assembly from the damper body, replace the piston with the chosen bleed pattern, check seals with your selected shock oil, then reassemble. Always confirm smooth shaft travel and absence of binding before running.

These are aftermarket tuning pistons for use on compatible T4 damper bodies only; do not force onto non-matching dampers. Keep a spare set when testing valving changes trackside so comparisons are easy.
