TRX-4 Scale & Trail Crawler

Traxxas is one of the most exciting brands in the RC world. In 1987, when the company introduced its first products, it made a big splash with monster trucks and buggy models. These days, Traxxas is getting a lot of attention with the TRX-4 Scale and Trail truck designs.

Traxxas TRX-4 Scale and Trail Crawler

In essence, TRX-4 Scale and Trail is a design philosophy that stays as faithful as possible to the full-size inspiration while delivering a powerful and dynamic performance on rugged paths. One of the most popular models is a scale replica of the Land Rover Defender but with higher clearance and stock tires that give RC pilots the ability to maneuver through puddles, sandy terrain, dirt roads, and muddy conditions. Another trail crawler that gets great reviews from RC drivers is the 4WD Sport Truck, which comes equipped with Canyon Trail tires right out of the box.

Traxxas RC Rock Crawlers

Rock crawlers also follow the TRX-4 design philosophy, but with added features such as wider rock rails with adjustable widths for technical piloting on rocky terrain. The bodies for rock crawlers are interchangeable with trail crawlers, so you can have classic Ford Broncos from the 1970s or new Jeep Wranglers. You can also upgrade these rock crawlers with Traxx treads like the ones that crush vehicles at monster truck shows.

RC Rock Crawler Parts and Kits

Along with rugged TRX-4 models, the RC Superstore also carries many parts and kits to get the most out of your trail and rock crawlers; these are all genuine Traxxas components appreciated by RC enthusiasts. One very popular accessory is the Traxxas Tool Set with a carrying pouch that includes six Allen wrenches, Phillips screwdrivers, ratchets, and telescoping bits to reach into the tightest spots within TRX-4 models.

RC Rock Crawler Chassis

For RC drivers who are more hands-on and enjoy spending time on the workbench before hitting the trails, Traxxas offers TRX-4 Chassis Kits that you can put together on your own. Each kit comes with heavy-duty axles, motor, locking differentials, and transmissions. Once the chassis is assembled, you can choose the body, charger, and battery pack of your choice. The kits include a detailed instruction manual with full-color images, and you can also reach Traxxas tech support staff through the website, email, or telephone should you have questions or need advice during the assembly process.
