For precise suspension tuning on the XRAY T4, Arrowmax AM-T4-308037B2 composite pistons are a focused upgrade. Their 3-hole 1.2mm bore provides small, controllable changes to shock flow that affect turn-in and mid-corner balance.
These pistons are made from a quality composite to resist wear and preserve port geometry over many runs. The 3-hole 1.2mm setup is appropriate for drivers wanting measured adjustments rather than broad changes in damping.
Engineered for the XRAY T4 series, the pistons install into standard shock internals and are a practical option for refining setups between meetings. They offer the flexibility to tune for different grip levels and track characteristics.
