Overview
Strengthen your differential housings with the Hot Racing Aluminum Differential Carrier Case. CNC-machined from 6061 aluminum and anodized black, this aluminum diff carrier fits the front, center, or rear position on the 1/8 Arrma Kraton, Outcast, Senton, Talion, and Typhon BLX platforms — replacing the stock plastic AR310433 differential carrier with a far stronger metal alternative.
Brushless 1/8 BLX drivetrains generate massive torque through the differentials; the stock plastic carrier flexes and cracks under sustained loads, while this aluminum upgrade locks the diff geometry rigid for consistent, long-lasting performance.
Key Features
- CNC-machined 6061 aluminum construction, anodized black
- Universal fit — front, center, or rear differential
- Direct replacement for Arrma AR310433 plastic differential carrier
- Includes four (4) ring gear screws
- Compatible across the 1/8 Arrma BLX lineup
Performance Benefits
- Stronger differential housing than stock plastic
- Reduced gear mesh deflection under high-torque loads
- Long-lasting durability — won't crack like plastic
- More consistent drivetrain feel over time
Usage Notes
Apply removable thread-locker on screws threading into aluminum. Use only silicone diff lubricant. Reuse stock spider and output gears (Arrma AR310433), gaskets, O-rings, and ring/pinion. Do not over-tighten ring gear screws.
