XRAY T4 Composite Pistons 3 Hole 1.1MM by Arrowmax AM-T4-308037B1  [AM-T4-308037B1]

Composite pistons for XRAY T4 shocks

This Arrowmax composite piston set is an RC-scale shock piston intended for XRAY T4 applications and compatible T-series assemblies. The four-piece pack provides a 3-hole 1.1mm piston profile in composite material that helps tune damping characteristics without changing shock oil or springs.

Use role and tuning: fit these pistons to standard-size T4 shock bodies to alter flow rate and mid-speed damping response. The 3-hole layout increases internal oil flow compared with single- or two-hole pistons, yielding a more responsive compression and rebound feel for track setups that need quicker mid-stroke reaction.

Installation notes: these pistons are sized for common T4 shock shafts and mount on standard retaining pins or small hex retainers depending on your shock design. Clean piston bores and use the same oil grade when swapping pistons to isolate the effect of piston geometry during setup changes. As with all RC-scale parts, inspect for burrs and ensure smooth piston travel before final assembly.
