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

3-Hole Composite Pistons Suited to XRAY T4

Arrowmax AM-T4-308037B3 composite pistons arrive as a quartet for use in XRAY T4 damper assemblies. The 1.3MM, 3-hole layout changes oil passage through the piston and helps fine tune damping characteristics without altering damper bodies or shafts.

These pistons are ideal when you need a simple damping change during setup or servicing. They function as drop-in replacements where the piston bore accepts 3-hole style inserts, and the composite build resists wear from repeated disassembly.

Fitting is standard: open the damper, replace the piston keeping the correct driveshaft orientation, inspect seals and shims, then reassemble and verify smooth stroke and no leaks. For setup work, pair the 1.3MM 3-hole piston with an appropriate oil and spring combination to balance rebound and compression.
