Overview
The Traxxas Differential locker (2 pcs) TRX7381 is an essential upgrade component for RC enthusiasts looking to enhance the performance and handling characteristics of their Traxxas models. Whether you're a seasoned RC car UK hobbyist or someone discovering the world of precision RC tuning, differential lockers play a crucial role in optimising traction and cornering stability. This genuine Traxxas spare part allows you to lock the rear differential with ease, transforming how your RC vehicle responds on varied terrain and track surfaces.
Differential lockers are among the most effective upgrades available for improving RC model performance without requiring extensive mechanical knowledge. By restricting differential movement, these components ensure that both wheels on an axle rotate at the same speed, delivering superior traction during acceleration and sharper handling characteristics through corners. The TRX7381 represents Traxxas's commitment to providing quality, reliable components that genuinely enhance the driving experience across multiple model platforms.
This pack contains two differential lockers, making it an ideal upgrade for owners who want to maximise performance on both front and rear axles, or for those building a competitive RC setup from scratch. Verified users report that these lockers work well and fit snugly, providing immediate and noticeable improvements to vehicle handling and traction control.
Key Features
- Two-piece pack — This product contains two separate differential lockers, giving you the flexibility to upgrade both axles or to have spares on hand for different setups and applications.
- Genuine Traxxas component — Manufactured by Traxxas and engineered to exacting standards, ensuring perfect compatibility and reliability with your RC model.
- Easy installation — These lockers are designed for straightforward fitment, allowing users to upgrade their differential without complex modifications or specialist tools.
- Proven performance enhancement — Differential lockers work by preventing the differential from allowing wheels to rotate at different speeds, which significantly improves traction during acceleration and provides more responsive handling through corners and during aggressive driving.
- Snug fit — Users report that the TRX7381 lockers fit snugly in place, providing secure retention and eliminating any movement or rattle during operation.
Technical Performance
The Traxxas Differential locker TRX7381 represents a fundamental but highly effective performance upgrade for RC vehicles. Differential lockers function by mechanically restricting the differential assembly, ensuring that power is distributed equally to both wheels on an axle. This engineering approach delivers measurable improvements in traction and handling response, particularly during high-acceleration runs, cornering at speed, and when driving on surfaces with varying grip levels. The design allows for snug fitment within the differential housing, preventing unwanted movement or rattling during aggressive driving sessions. Built to Traxxas's recognised quality standards, these lockers integrate seamlessly with genuine Traxxas drivetrain components. Users who have installed the TRX7381 consistently report improved vehicle control and more predictable handling characteristics, with particularly noticeable benefits when locking the rear differential for enhanced straight-line acceleration and improved cornering stability.

Frequently Asked Questions
- What is a differential locker and why would I need one? — A differential locker is a mechanical component that restricts movement within the differential assembly, forcing both wheels on an axle to rotate at the same speed. This dramatically improves traction during acceleration and provides sharper handling response, especially during competitive driving or on challenging terrain. Most serious RC hobbyists and racers upgrade to differential lockers as one of their first performance modifications.
- Will the TRX7381 fit my Traxxas RC model? — The TRX7381 is a genuine Traxxas component engineered for compatibility with multiple Traxxas models. However, we recommend checking your vehicle's service manual or contacting our RC Model Shop team to confirm compatibility with your specific model before ordering.
- How difficult is it to install differential lockers? — Installation is straightforward for users with basic RC maintenance experience. The lockers fit snugly into the differential assembly without requiring specialist tools or complex modifications. If you're new to RC tuning, our team at RC Model Shop can provide guidance to help you complete the installation confidently.
- What difference will I notice after installing these lockers? — After installation, you'll experience noticeably improved traction during acceleration, sharper and more responsive cornering, and better overall stability when driving on varied surfaces. Many users report that locking the rear differential in particular provides a dramatic improvement in handling predictability and control.
- Can I use just one locker or do I need both? — You can use one locker for a single axle or install both for maximum performance across front and rear differentials. Many users choose to lock the rear differential first to experience the most significant handling improvement, then add front locking for additional benefits depending on their driving style and track conditions.
