Overview of front X shock piston for B-MAX4

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

Fit this piston set to tweak damper response without modifying springs or shock bodies. The task involves normal shock disassembly, swapping the pistons, carefully bleeding air, and refilling the shock oil. Check seals and O-rings during the rebuild to prevent leaks.

During setup, pair the pistons with different shock oil viscosities and assess the impact on compression and rebound on test runs. The black finish minimises visible change and matches common shock assemblies.

Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Are these pistons compatible with all B-MAX4 shock bodies?

They are designed for the front shocks used on the listed B-MAX chassis. Confirm the internal dimensions and shaft size match your shock body before fitting to ensure correct operation.

Will I need new seals after fitting these pistons?

If your existing seals and O-rings show wear, replace them during installation. Fresh seals help maintain consistent damping and prevent oil leakage after piston replacement.

Is the black finish purely cosmetic?

Yes. The black finish is chosen to match common shock assemblies and does not alter piston function; tuning results depend on piston profile and oil viscosity rather than color.
