Key Features
- 6061-T6 Aluminium Construction — Milled from high-grade 6061-T6 aluminium, this housing provides the strength and rigidity needed to handle the extreme torque and power of modern brushless 4WD RC trucks. Aluminium offers an excellent balance of weight and durability, making it the professional choice for demanding applications.
- Brilliant Anodised Finish — The orange anodised coating not only gives the housing an attractive appearance that complements Traxxas orange colour schemes, but also provides corrosion resistance and protection against wear during intensive off-road use. The anodising process creates a hard, protective surface that extends component life.
- Factory-Fit Precision — As a genuine Traxxas accessory made by Traxxas for Traxxas vehicles, this housing guarantees perfect fitment every time. No modification, adjustment, or compatibility issues—simply install and enjoy improved performance. This is the advantage of choosing authentic OEM parts rather than aftermarket alternatives.
- Front and Rear Compatibility — This single housing design works in both front and rear differential positions on compatible Traxxas models. This versatility means you can upgrade your entire differential system with a single part number, simplifying your spares inventory and maintenance routine.
- Premium Quality Construction — Traxxas components are engineered to the highest standards, with precision machining and quality control that ensures every housing meets exacting specifications. This is why serious RC bashers and competitors choose Traxxas parts to keep their vehicles running strong.
Technical Performance
The TRX7780 differential housing represents the pinnacle of chassis engineering for high-performance brushless 4WD RC vehicles. Manufactured from 6061-T6 aluminium, one of the most trusted alloys in motorsport applications, this housing delivers exceptional strength-to-weight performance. The material has been specifically selected for its excellent machinability, which allows Traxxas engineers to create precisely toleranced components that work flawlessly with your vehicle's drivetrain. The anodised finish provides both aesthetic appeal and functional protection—the hard anodic coating resists corrosion from dirt, moisture, and salt spray encountered during outdoor RC driving sessions across the UK. This housing is compatible with the full range of X-Maxx and XRT models, including the X-Maxx Belted 4WD Brushless RTR 8S versions in all colour options, the X-Maxx Ultimate variants, and both the XRT VXL-8S and XRT Ultimate platforms. The robust construction ensures reliable operation even under the extreme loads generated by powerful brushless motors and lithium polymer batteries. This is an essential upgrade for any serious RC enthusiast running an 8S brushless system who demands maximum durability and professional-grade performance.
