SEE FULL COMPATIBILITY LIST BELOW
If you’re tired of plastic transmission case flex, inconsistent gear mesh, or a drivetrain that gets noisy after hard runs, this is the upgrade built for you. The Cobra Racing billet case kit replaces the stock-style 2WD transmission housing with a rigid, precision-machined 7075-T6 aluminum setup that’s designed to keep everything square, supported, and aligned under load—especially when you’re running brushless power, tall gearing, big tires, or just bash like you mean it.
This kit is for drivers who want reliability + repeatable performance: smoother power transfer, less “walking” in the drivetrain, and a stronger foundation for your gears, bearings, and motor mount alignment.
What’s Included (Complete Set)Billet 7075-T6 aluminum transmission case
Transmission gear cover
(2) transmission mounting brackets
All required installation hardware for a full, proper install
Stops case flex that can throw off gear mesh under throttle
Helps reduce premature wear on spurs, idlers, and bearings
Stronger mounting and alignment for consistent drivetrain geometry
Built for bashing, racing, and high-power setups (2S/3S brushless, heavy tires, speed runs)
Fits Traxxas 1/10 2WD platforms that use the standard or Magnum 272 / 272R-style transmission family (including VXL variants). Verified compatibility is consistent across the Bandit/Rustler/Stampede/Slash 2WD ecosystem, including Drag Slash-style applications.
