Yokomo B-MAX4 Rear Weight 50g Brass Tuning Part - Arrowmax AM-MAX4-008  [AM-MAX4-008]

Compact 50g rear weight for Yokomo B-MAX4

The Arrowmax AM-MAX4-008 rear weight is an RC-scale ballast made for the Yokomo B-MAX4 chassis, delivered as a single 50g brass piece. It is intended to adjust rear mass distribution for setup work on grippy surfaces and is not a representation of real vehicle components.

CNC-machined from brass, the unit carries a laser-etched Arrowmax logo and a milled finish, offering a dense, compact mass for fine adjustments. It is typically used where extra rear ballast helps with rotation, traction transfer, and corner exit stability during tuning.

Installation is simple for those used to B-MAX4 assemblies: the weight mounts at the rear mass point to shift balance backward during setup cycles and works alongside suspension and mechanical tuning rather than replacing them.

This brass rear weight is a practical tuning option for B-MAX4 drivers aiming to tweak rear-end behaviour when testing on high-grip surfaces.
