Yokomo B-MAX4 RF Tuning Weight Brass 18g Mount by Arrowmax AM-MAX4-009  [AM-MAX4-009]

Front-right brass tuning mount for B-MAX4

The Arrowmax AM-MAX4-009 is an RC-scale front-right replacement mount developed for front-end setup work on the Yokomo B-MAX4 chassis. The machined brass 18g mass is intended to provide a local weight bias that influences suspension response and roll without altering shock mounting geometry.

This mount is useful when you want a modest shift in unsprung and sprung weight or a change in mounting stiffness to fine-tune turn-in and corner balance. It is aimed at 1/10 electric touring car setups and designed to pair with the stock B-MAX4 shock tower mounting points.

Fitting the part calls for standard RC hand tools and checking that fasteners seat correctly; confirm thread engagement and use appropriate torque compared with the originals to avoid damage. The description applies only to the supplied suspension mount item.

For tuners seeking subtle front-end adjustments on the B-MAX4, this brass RF mount offers a small, dependable way to tweak handling and weight distribution without major component swaps.
