XRAY T4 1.1mm 3-Hole Composite Pistons Upgrade - Arrowmax AM-T4-308037B1  [AM-T4-308037B1]

3-hole composite pistons for T4 shock tuning

The Arrowmax AM-T4-308037B1 kit contains composite 3-hole 1.1mm pistons intended for XRAY T4 and compatible T-series shock assemblies. Supplied as a set of four, the pistons are designed to alter damping characteristics while retaining your existing oil and spring setup.

Performance notes: install these pistons into standard T4 shock bodies to adjust internal flow rates and mid-stroke damping. The three-hole geometry increases oil passage compared with fewer-hole designs, producing a livelier compression and rebound response suited to circuits that demand quick transitions.

Fitment guidance: these pistons match common T4 shock shaft dimensions and secure with typical retaining pins or small hex retainers depending on the shock design. Maintain clean piston bores and keep oil grade consistent when testing piston changes to isolate geometry effects. Inspect each piston for manufacturing imperfections and confirm smooth travel before sealing the shock.
