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

Precision 3-Hole Pistons for XRAY T4 Dampers

Arrowmax AM-T4-308037B3 composite pistons are supplied as a set of four and are engineered to fit XRAY T4 damper assemblies. The 3-hole, 1.3MM configuration modifies oil flow through the piston to alter damping without changing damper bodies or shafts.

Fit these pistons when you want a straightforward change to damping behaviour during setup or routine servicing. They act as direct replacements in T4 shock bodies that accept 3-hole piston inserts, and the composite compound is selected for durability under repeated assembly and teardown.

Installation follows the usual routine: strip the damper, fit the piston with the correct driveshaft orientation, check seals and shims, then reassemble and confirm consistent travel and no leaks. For tuning, match the 1.3MM 3-hole piston with suitable shock oil and spring rates to refine rebound and compression balance.
