Overview
Strengthen your differential housings with the Hot Racing Modular Aluminum Differential Carrier Case. CNC-machined from 6061 aluminum and anodized black, this differential carrier fits the front, center, or rear position on the entire 1/8 Arrma BLX lineup (Kraton, Notorious, Outcast, Senton, Talion, Typhon) plus the 1/7 Limitless and Infraction speed-run platforms.
Featuring a steel pinion bushing for longevity and an O-ring seal for better diff oil retention and reusability, this modular case is a comprehensive differential housing upgrade that improves both strength and serviceability over the stock plastic carrier.
Key Features
- CNC-machined 6061 aluminum construction, anodized black
- Steel pinion bushing for extended longevity
- O-ring seal for better diff oil retention and reusability
- Universal fit — front, center, or rear differential
- Modular design simplifies servicing
Performance Benefits
- Stronger differential housing than stock plastic
- Better diff oil retention via O-ring seal
- Steel pinion bushing extends service life
