Skill Level:Intermediate

The TRX-4 Sport combines the unbeatable ground clearance and driving dynamics of Traxxas portal axles, sticky Canyon® Trail tires, and a lightweight pickup truck body for a leaner, performance-focused new TRX-4. The Sport’s unique bumpers, wheels, and body were designed for increased climbing versatility. Whether it’s a fun trail run or a hardcore technical crawl, the TRX-4 Sport’s capability and performance-built approach takes your outdoor adventure to a new level.


High-Performance Body

Designed for ultimate all-terrain performance, the TRX-4 Sport's lightwight body keeps the CG low for improved stability when climbing. Low-profile bumpers increase the approach and departure angles while red differential covers and D-rings add off-road style.


Waterproof Electronics

The TRX-4 is fully waterproof, not "splash resistant." There is a big difference, Traxxas' patented innovation gives you the freedom to tackl creeks, snow, and mud without worrying about water in your electronics.


The Power of Portals

Portal axles lift the truck at the wheels for huge center pumpkin ground clearance. In order to achieve the same clearance with straight axles, your tires would have to be over an inch taller than the tires on the TRX-4 Sport.


Rugged TRX-4 Chassis Design

The TRX-4 Sport tramples the satus quo with extreme versatility and off-road capability. Performance and technology combine in a revolutionary new chassis that looks as good as it performs.
