Overview
The Traxxas Differential assembly, complete TRX7078 is an essential drivetrain spare part designed for a range of popular 1/16 scale Traxxas RC models. Whether you're running a Slash, E-Revo, Rally, or Summit, this complete differential assembly ensures smooth power delivery and optimal handling characteristics across all terrain types. As a dedicated RC car UK enthusiast, you'll appreciate that having quality replacement differential assemblies on hand is crucial for maintaining peak performance and extending the lifespan of your brushless RC truck or monster truck.

Key Features
- Complete Assembly Design — This is a fully assembled differential unit ready for installation, saving you time and ensuring correct assembly by the factory standards. Rather than purchasing individual gears and components, you get a tested, complete assembly that meets Traxxas specifications perfectly.
- 1/16 Scale Compatibility — Engineered specifically for 1/16 scale Traxxas vehicles, this differential provides the correct gear ratios and mechanical specifications needed for vehicles in this popular compact scale range. The 1/16 scale is ideal for high-speed backyard bashing and indoor racing with smaller footprints than larger RC models.
- Multi-Model Compatibility — This assembly is compatible with the Traxxas E-Revo VXL 1/16 in both Purple and Blue X variants, as well as the Traxxas Slash 1/16 4x4 short course truck, making it a versatile spare for owners of multiple vehicles in this scale.
- Genuine Traxxas OEM Part — As an authentic Traxxas component, this differential meets all original manufacturer specifications and tolerances. Using genuine parts ensures reliability and maintains compatibility with other genuine Traxxas components in your vehicle.
- Drivetrain Reliability — The differential is a critical component in the drivetrain system, responsible for distributing engine torque to the wheels whilst allowing for speed variations during cornering. A quality differential assembly maintains traction and handling precision.
Technical Performance
The Traxxas Differential assembly TRX7078 is engineered to handle the demands of modern 1/16 scale brushless RC vehicles with performance-level powertrains. As a complete assembly, it has been precision-manufactured to tight tolerances that ensure smooth operation and minimal friction loss through the drivetrain. The assembly incorporates Traxxas's proven differential design philosophy, which balances traction during acceleration with the ability to allow inside and outside wheels to rotate at different speeds during turns. This is essential for maintaining stable handling across varied terrain types, from smooth tarmac to rough grass and dirt tracks. The complete assembly approach eliminates potential assembly errors and ensures all components are properly fitted and functioning in harmony. For users of high-performance brushless RC trucks and monster trucks in this scale, maintaining a spare differential assembly is a smart move, as differential components do experience wear with repeated use, particularly during high-torque acceleration or aggressive cornering. Customer feedback suggests that differential components can experience stress under heavy use, reinforcing the importance of having genuine replacement assemblies available. The engineering and build quality of this Traxxas component reflect decades of RC vehicle manufacturing experience and field-proven reliability.
