Yokomo B-MAX4 Rear Ballast 50g Milled Brass - Arrowmax AM-MAX4-008  [AM-MAX4-008]

Rear tuning mass for Yokomo B-MAX4

This Arrowmax AM-MAX4-008 rear weight is a 50g brass ballast designed for the Yokomo B-MAX4 chassis, supplied as a single solid piece. It is intended to alter rear mass for setup and tuning on high-traction surfaces rather than serve any non-RC application.

Machined from brass with a milled finish and featuring a laser-etched Arrowmax logo, the weight gives a compact, high-density mass for controlled adjustments. Use it to influence rotation, transfer of traction, and mid-corner to exit stability during setup runs.

Installation is routine for modellers comfortable with B-MAX4 components: the weight attaches at the rear mass mounting point to shift balance rearward and is meant to complement suspension and chassis changes rather than replace them.

Add this 50g brass unit to your B-MAX4 toolkit when you need a straightforward way to tweak rear balance during track testing.
