Tamiya M06 Derlin 3-Hole Damper Piston 3RAC-DP04 by 3Racing  [3RAC-DP04]

Precision Derlin 3-hole pistons for M06 shocks

This machined Derlin 3-hole damper piston is a scale replacement made to fit Tamiya M06 shock cartridges. The machined surface and three-port layout change how oil flows past the piston, helping to stabilise valve behaviour for more predictable tuning during setup and testing.

Role and fitment: the piston functions as the internal valve element inside standard M06 shock cartridges and influences compression and rebound response without changing the shock's external dimensions. Use the piston porting together with spring and oil adjustments to refine handling.

Service tips: treat these as standard shock internals when rebuilding, keep the ports free of grit, and inspect the Derlin face for wear. Ensure piston orientation matches your cartridge design and check seals and shafts for nicks to prevent leaks. Match shock oil to the porting for best results.
