B-MAX4 Front X Shock Piston Set - BM-S106 by Yokomo  [BM-S106]

Front X damper piston upgrade for B-MAX4

This optional front X shock piston set fits B-MAX4 scale RC cars and is supplied as a two piece kit for the front dampers. The components replace the original front shock pistons and are intended for suspension tuning on the listed B-MAX chassis.

Use this piston set to alter damper response without changing springs or shock bodies. Installation requires basic shock disassembly, swapping the pistons, careful air bleed, and refilling shock oil. Inspect shaft seals and O-rings for wear during reassembly.

For setup work, pair these pistons with your choice of shock oil viscosity and observe the effects on compression and rebound during test runs. The black finish keeps the look consistent with common shock assemblies and limits visible change after fitting.
