Yokomo BM-S106 X Shock Piston Black — Front X shock piston for B-MAX4, 2 pcs  [BM-S106]

Front X shock piston for B-MAX4

This is an optional front X shock piston set for B-MAX4 scale RC cars supplied as a 2 pcs kit. The parts replace the front shock pistons and are intended for RC-scale suspension tuning on the listed B-MAX chassis.

Use this piston set when you want a straightforward way to alter damper response without modifying springs or shock bodies. Installation requires basic shock disassembly, piston swap, and careful bleed and oil refill. Check shaft seals and O-rings for wear during reassembly.

For tuning, pair the pistons with your preferred shock oil viscosity and observe changes in compression and rebound feel on practice runs. The set is supplied black to match common shock builds and to minimize visual change when installed.
