Overview
Reinforce the rear suspension geometry on your Arrma 1/8 4x4 with the Hot Racing Aluminum Rear Lower Rear Hinge Pin Brace Arm Mount. CNC-machined from 6061 aluminum, this rear hinge pin brace mounts at the rear lower suspension position, replacing the stock plastic and stamped aluminum hinge pin mount with a single rigid aluminum component that locks the hinge pin firmly in place.
By eliminating the hinge pin walk and flex common to factory mounts, this upgrade keeps your rear suspension geometry consistent — critical for predictable handling under brushless power and aggressive driving. A secure M4 set screw maintains hinge pin position even under the most severe driving conditions.
