T4 shock piston upgrade with Arrowmax parts

The Arrowmax AM-T4-308037A3 pack delivers four composite pistons purpose-built for XRAY T4 shock units. Each piston features four flow holes and a 1.3mm bore, making them suitable when matching piston geometry to shock bodies and oil choices during setup.

To install on standard T4 shocks: remove the shock shaft assembly, replace the old piston with the Arrowmax composite piston, then rebuild the shock with the correct oil level and seal condition. Confirm free piston travel and correct endplay before final assembly to prevent binding.

These pistons change damping by modifying internal flow rates. The 4-hole 1.3mm pattern gives a predictable mid-range response that helps tame bumps while maintaining steady rebound. Use small changes in oil weight and spring rates to fine tune handling for closed circuits or rough layouts.

Are these pistons compatible with aftermarket T4 shock bodies?

They are compatible with most standard XRAY T4 shock bodies. Double-check shaft diameter and internal clearances on non-standard aftermarket bodies.

What advantages do composite pistons offer?

Composite pistons are light and resist corrosion, providing consistent flow characteristics without the stiffness of metal pistons.

How do I balance compression and rebound with these pistons?

Start with your usual oil and springs, then adjust oil viscosity in small steps and swap springs as needed until the car feels controlled over bumps and through corners.

Is 1.3mm suitable for all track types?

The 1.3mm 4-hole layout is a mid-range option that works well on a variety of surfaces; use heavier or lighter oil to adapt to specific track conditions.
