Precision Brass Arm Mount for Consistent Yokomo B-MAX2 Handling

The Arrowmax AM-MAX2-018 brass upper arm mount is a purpose-made replacement for the Yokomo B-MAX2 plastic mount. It increases local mass and improves resistance to impact and wear, providing steadier behaviour on grippy tracks. The unit weighs 26 grams and is often used by competitors refining corner balance.

Brass Benefits Explained

Using brass adds targeted ballast to the arm pivot, which can reduce quick weight shifts and help tyres maintain grip during transitions. The Arrowmax part keeps the B-MAX2's geometry intact while delivering a tangible change in feel.

Does this change require different shock settings?

You may need small adjustments to damping or spring rate to match the added weight. Start with minor damping increases and test lap consistency.

Will brass increase wear on mating parts?

Brass is harder than typical plastics, so check mating surfaces for wear and keep parts clean. Proper maintenance will avoid accelerated wear.

Is tuning required after fitment?

Minimal tuning is often needed. Many drivers only tweak front spring or tyre choice to balance the extra mass for best lap times.

Can this be used alongside other aluminium or brass upgrades?

Yes, but stacking several heavy parts will shift overall balance significantly. Adjust setup progressively and test changes one at a time.
