Overview
Reinforce your center differential housing with the Hot Racing Aluminum Center Differential Brace Gear Cover. CNC-machined from solid aluminum, this center diff brace and gear cover replaces the Arrma stock plastic diff mount (ARA320499) found on the 6S BLX Kraton, Notorious, Outcast, Talion, Infraction, and Limitless platforms — eliminating the cracking and flexing that plagues the stock plastic component under brushless 6S power.
By bracing the center diff with rigid aluminum, this upgrade improves drivetrain stability and protects the gearbox from impact damage. Essential for high-power 6S BLX builds and speed-run platforms.
