Yokomo BM-S106 Front X Shock Pistons for B-MAX4, 2 pc Black  [BM-S106]

Front piston upgrade for B-MAX4 shocks

This front X shock piston set is an optional replacement for B-MAX4 front dampers and comes as a two piece kit. The parts are intended for RC suspension tuning on the specified B-MAX chassis.

Install the pistons to modify damper character without touching springs or shock bodies. The job requires removing the shocks, swapping pistons, bleeding trapped air, and topping up shock oil. Always check seals and O-rings for any wear when reassembling.

When testing setups, combine these pistons with different shock oil viscosities to evaluate changes in compression and rebound. The black finish helps maintain a factory look after installation.
