ARRMA ARA320781 Aluminum RR Suspension Mount

This black anodized ARRMA aluminum RR (rear-rear) suspension mount provides the perfect replacement for the kit-supplied item. The suspension mounts anchor the inner hinge pins that the lower arms pivot on, and the RR position sets the rear toe angle — making this small block one of the geometry-critical parts on the chassis.

Machined from aluminum rather than molded composite, this mount holds the hinge pin precisely without flexing or wallowing under hard cornering and landing loads. That rigidity is what keeps rear toe consistent lap after lap: a worn or cracked mount lets the pin shift, and the truck's rear grip becomes unpredictable as the geometry wanders.

The black anodized finish resists corrosion and wear at the pin bores while matching the factory look. Aluminum suspension mounts are also the part that takes the load when the chassis bottoms hard — replacing a bent one restores the suspension's true alignment.
