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

Composite 3-Hole Pistons Designed for XRAY T4

Arrowmax AM-T4-308037B3 composite pistons are provided as a set of four for use in XRAY T4 damper assemblies. The 1.3MM, 3-hole configuration controls fluid flow through the piston to adjust damping characteristics without swapping damper bodies or shafts.

These pistons are useful when a quick change to damping is required during setup or servicing. They fit as direct replacements in compatible T4 shock bodies that accept 3-hole pistons, and the composite construction helps resist wear from frequent rebuilds.

Fitting is straightforward: strip the damper, install the piston with the correct driveshaft alignment, inspect seals and shim packs, then reassemble and check for smooth stroke and leak-free operation. For tuning, use the 1.3MM 3-hole piston with the appropriate oil grades and spring rates to achieve the target rebound and compression balance.
