Overview
Stiffen up the rear chassis and protect the gear case on your Traxxas 4-Tec 2.0 4WD with the Hot Racing CNC Billet Aluminum Speed Run Gear Cover and Rear Chassis Brace. CNC-machined from solid billet aluminum, this dual-function part replaces the stock gear cover with a stronger aluminum component AND adds critical chassis stiffness through the rear of the vehicle — exactly what's needed for high-speed running.
At speed-run velocities, even small amounts of chassis flex can lead to drivetrain misalignment, drivetrain damage, and unpredictable handling. This combined gear cover and chassis brace eliminates that flex, locking the rear chassis tight and protecting the gear case in the process. A smart, dual-purpose upgrade for any speed-run-focused 4-Tec 2.0 build.
