Yokomo B-MAX4 Rear Suspension Mount 19g Brass by Arrowmax AM-MAX4-010  [AM-MAX4-010]

Rear suspension mount for B-MAX4

This rear suspension mount is a small-scale RC upgrade part designed for the Yokomo B-MAX4 chassis, supplied by Arrowmax as model AM-MAX4-010. Made from brass and specified at 19g, the component is intended to change rear-end mass distribution and influence rear suspension response in tuning setups.

Use this mount when you need a predictable way to add mass to the rear suspension area for tuning purposes. In practice it affects rotational inertia and transient response of the rear end, which can help when testing balance and handling on carpet or asphalt club tracks. The design is RC-scale and intended only for model car use.

Installation notes: mount the part to the rear suspension mounting points on a Yokomo B-MAX4 chassis, verify thread and fastener length before final fit, and recheck suspension travel after installation. When tuning, change one variable at a time and record ride-height and body-roll differences to isolate the mount's effect.

As a focused tuning part, this brass rear mount gives a simple, reversible way to experiment with rear mass and handling on a Yokomo B-MAX4; use measured testing to evaluate its effect in your setup.
