Overview
The Traxxas Differential Cover (Black) TRX9738 is an essential replacement part and protective upgrade for RC enthusiasts in the UK who own Traxxas TRX-4M trail trucks and crawlers. This two-piece set provides durable protection for your vehicle's critical differential components, whether you're running front or rear differentials on your 1/18 scale RC crawler. Whether you're a seasoned RC hobbyist exploring advanced maintenance, a weekend basher pushing your truck to its limits, or someone discovering the world of RC off-road vehicles for the first time, these differential covers are a practical investment in your model's longevity and performance.
Differential covers are far more than cosmetic upgrades—they shield the internal gearing and differential mechanisms from mud, water, dust and debris that accumulates during outdoor trail running and rock crawling sessions. The Traxxas TRX-4M has become one of the most popular 1/18 scale RC crawlers in the UK market, praised for its realistic suspension geometry, authentic truck styling and genuine off-road capability. By maintaining your TRX-4M with genuine Traxxas parts like these differential covers, you ensure your investment continues to deliver the performance and reliability you expect. These covers are fully compatible with the entire TRX-4M range, including the Ford Bronco, Land Rover Defender, Chevrolet K10 and Ford F-150 High Trail variants.
Each pack contains two differential covers finished in sleek black, perfectly matching the factory aesthetics of most TRX-4M builds. The design allows for easy installation on both front and rear differentials, making this a versatile maintenance part for any TRX-4M owner. Whether you're preparing for serious competition, casual Sunday afternoon bashing or meticulous trail recreation, keeping spare differential covers on hand demonstrates the kind of forward-thinking maintenance that separates casual operators from dedicated RC enthusiasts.
Key Features
- Two-Piece Set — This pack includes two differential covers, giving you the option to upgrade both front and rear differentials or keep a spare on hand for when the primary cover gets damaged during aggressive off-road sessions.
- Universal Front or Rear Compatibility — These covers fit both front and rear differentials on TRX-4 and TRX-4M models, providing flexible options for protecting your RC crawler's drivetrain regardless of which axle you prioritise.
- Premium Black Finish — The glossy black coating matches the factory appearance of most TRX-4M variants, maintaining the authentic scale appearance of your truck while providing protective functionality.
- Genuine Traxxas Engineering — As official Traxxas parts, these covers are engineered and tested to OEM specifications, ensuring precise fit, durability and seamless integration with your RC crawler.
- Splash and Debris Protection — The covers shield your differential gearing from water ingress, mud accumulation and dust contamination that would otherwise degrade performance and lifespan during trail running and rock crawling.
- Easy Installation — Designed for straightforward bolt-on fitment, these covers can be swapped out or replaced in minutes without requiring specialist tools or technical expertise.
Technical Performance
The TRX9738 differential covers represent Traxxas's commitment to protecting the heart of your RC crawler's drivetrain. The differential is one of the most critical components in any four-wheel-drive RC vehicle, distributing torque between left and right wheels and allowing them to rotate at different speeds during cornering and technical terrain navigation. Without proper protection, mud, water and debris ingress can cause binding, increased friction, noise and eventual mechanical failure. These black covers provide a physical barrier against the elements whilst maintaining the aerodynamic profile and scale appearance of your TRX-4M. The engineering ensures that cooling and gear operation are not compromised—the covers are designed to work in harmony with the differential's heat dissipation requirements during high-intensity trail running. Built from durable plastic materials matched to Traxxas's exacting standards, these covers withstand repeated installation cycles, vibration from rough terrain and the occasional impact from obstacles. UK RC enthusiasts appreciate the quality assurance that comes with genuine Traxxas parts, knowing that each cover has undergone rigorous durability testing before reaching the market.

Frequently Asked Questions
- Which TRX-4 and TRX-4M models are these differential covers compatible with? — These covers fit front or rear differentials on all TRX-4 models and TRX-4M variants, including the Ford Bronco (Black, White, Area 51, Blue, Red and Orange versions), Land Rover Defender (Silver, Tan, Black, Green, Light Blue and Pink options), Chevrolet K10 High Trail (Red, Black and Blue versions), Ford F-150 High Trail (Blue, Black and Brown), and TRX-4MT Monster Truck variants (F150 and K10 in multiple colours).
- Why would I need replacement differential covers for my RC crawler? — Differential covers protect the critical gearing inside your drivetrain from water, mud and debris that accumulate during trail running and rock crawling. Without covers, contaminants can cause friction, binding and eventual mechanical damage. Many RC enthusiasts carry spare covers as consumable maintenance items, especially if they frequently run in wet or muddy conditions.
- Are these covers difficult to install? — No—these covers are designed for straightforward bolt-on installation. Most UK RC enthusiasts can swap them out in just a few minutes using basic tools. No specialist knowledge or advanced technical skills are required.
- Can I use these covers on both front and rear differentials? — Yes, that's one of the key benefits of this design. The covers are compatible with both front and rear differential housings on TRX-4 and TRX-4M vehicles, giving you flexibility in how you protect your drivetrain.
- What makes genuine Traxxas parts worth buying instead of aftermarket alternatives? — Genuine Traxxas parts are engineered and tested to factory specifications, ensuring perfect fit, durability and compatibility with your vehicle. Authorised retailers like RC Model Shop stock authentic parts backed by manufacturer warranty and quality assurance. Aftermarket alternatives may fit poorly or wear quickly, ultimately costing more in the long run.
