RC Shock Piston 13mm 2 x 1.7mm Serpent 500902  [SER500902]

13mm bore shock piston for precise damping control

The Serpent 500902 is a 13mm-bore piston featuring two 1.7mm ports, intended as a replacement element for RC dampers. It controls internal oil flow to allow more refined compression and rebound adjustments during setup.

Installation: install this piston in shock shafts and bodies compatible with a 13mm piston bore, where it sits between the shock shaft and piston head as part of the flow path. During assembly verify port alignment and that the piston does not bind on the shaft.

Tuning role: the dual 1.7mm configuration increases overall flow area versus smaller single ports, affecting both compression and rebound damping. Combine piston choice with oil weight, shim stacks and springs to tune balance and steering response.

Use this piston for moderate flow needs to smooth mid-speed damping; always bench and track test changes to confirm their influence on vehicle behaviour.
