Must-Have Traxxas TRX 4M Upgrades for Your RC Crawler


The Traxxas TRX 4M is an impressive crawler that offers excellent capabilities and performance. While the stock version of this RC car is already remarkable, adding some Traxxas TRX 4M upgrades can take it to the next level. In this article, we will explore the top Traxxas TRX 4M parts and upgrades that you should consider adding to enhance its power, speed, and overall performance.

Speed Gears

One common complaint about the Traxxas TRX 4M is its relatively slow speed compared to other Traxxas RC cars. Fortunately, you can address this by changing the speed gears. Upgrading the speed gears will make your TRX 4M faster and more exciting to drive. It’s important to note that changing gears can be a bit complicated for beginners, so it’s advisable to seek assistance from someone experienced to ensure proper installation and avoid any damage.


The stock servo in the Traxxas TRX 4M may lack power and endurance, particularly for off-road crawling. Upgrading the servo to a more powerful one will significantly improve the driving experience, especially when tackling challenging terrains. A stronger servo ensures better control and responsiveness, enhancing the overall performance of your TRX 4M. Upgrading the servo is compatible with both the TRX 4M Bronco and Defender models.

Utility Trailer

If you’re looking for a fun and easy upgrade for your Traxxas TRX 4M, adding a utility trailer is a great option. It not only enhances the driving experience but also provides an opportunity for imaginative play. Installing and removing the utility trailer is simple and requires no technical knowledge. This upgrade is compatible with both the TRX 4M Bronco and Defender models.


Upgrading the body of your Traxxas TRX 4M is a quick and straightforward way to customize its appearance. The Traxxas TRX 4M body features a clipless design, allowing for easy installation and removal. You can choose from a variety of colors, including white, red, blue, cactus, cyber, and more. Switching to a new body can give your TRX 4M a fresh look and allow for personalization.

Pro Scale Light Kit

The Pro Scale light kit is a cool upgrade that adds an extra level of realism and functionality to your Traxxas TRX 4M. This kit includes lights that can be mounted on the crawler and controlled remotely. The Traxxas TRX 4M models are designed with an internal cage that makes installing the light kit easier. While the installation may require some technical know-how, the results are stunning, providing a more immersive driving experience.

Wheels and Tires

Optimizing the wheels and tires of your Traxxas TRX 4M can significantly improve its off-roading performance. There are various options available, including different tire patterns and wheel designs. Upgrading the wheels and tires not only enhances the traction and grip but also allows for customization of the appearance. These upgrades are specifically designed for Traxxas TRX 4M models and are relatively affordable.

Aluminum Shocks

The shocks play a crucial role in the suspension system of any RC car, particularly for off-roading crawlers. Upgrading to aluminum shocks can improve handling and durability, allowing your Traxxas TRX 4M to handle rough terrains with ease. These shocks are available in different colors, such as green, blue, orange, and red, providing options for customization while enhancing performance.

Aluminum Driveshafts

Upgrading the driveshafts of your Traxxas TRX 4M to aluminum versions can significantly enhance steering performance and overall durability. Aluminum driveshafts are strong, rigid, and capable of handling the pressures encountered during off-road crawling. These upgrades are available in various colors, allowing you to customize your TRX 4M’s appearance while improving its performance.


Adding Traxxas TRX 4M upgrades to your RC crawler can unlock its full potential and provide a more thrilling driving experience.
