This is the Traxxas TRX-4 Sport 4WD RTR Rock Crawler Trail Truck. 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 Sports unique bumpers, wheels, and body were designed for increased climbing versatility. Whether its a fun trail run or a hardcore technical crawl, the TRX-4 Sports capability and performance-built approach takes your outdoor adventure to a new level. Just add a battery and charger to be ready to take on the world!
Outfitted with radically innovative technology, the TRX-4 Sport minimizes weight to maximize performance.
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.
Heavy Duty Steel Frame Rails: A thick 1.5mm steel ladder frame with molded cross members provides exceptional torsional rigidity to resist even the worst chassis twisting articulation. This extremely rigid backbone lets the suspension do the work it was designed to do. Youll feel the difference on trails where the elimination of chassis flex allows for precise wheel placement when navigating technical terrain.
The innovative shock towers allow four separate bolt-on wheelbase positions: 300, 312, 324, and 336mm to accommodate custom body fitment. Further fine tuning is possible with the axle links and adjustable shock position.
Molded Wire Retainers
The finer details matter so we incorporated wire retainers into the frame rails, which provide a clean look and keep the wiring more secure from off-road hazards.
Dual-Fit Battery Tray
Tactical Units dual-fit battery tray offers extreme flexibility when choosing batteries. For extended run times, the large upper tray accommodates a full-length 5000 mAh 3-cell LiPo or 7600 mAh 2-cell LiPo. A hinged battery strap provides quick and secure battery mounting without pins to lose in the field. The innovative strap flips over to adjust for different height batteries. A smaller integrated tray accepts smaller Traxxas batteries (that fit our 1/16 scale models) for increased forward weight bias.
Tough floor pans integrate with the wheel wells to enhance the scale appearance and keep debris out of the chassis.
Aluminum Scale Shocks
All new oil-filled coil-over GTS shocks were created exclusively for the TRX-4 chassis to smooth out even the roughest trails. These silver-anodized aluminum shocks deliver silky-smooth damping and feature threaded bodies for easy ride height adjustment. The convincing scale realism looks great and they perform even better with an O-ring cap seal and dual X-ring shaft seals.
Heavy Duty Steel Links
Thick 5mm diameter steel links feature tough, fully-captured heavy-duty rod ends with steel hollow balls for exceptional strength and durability. This is one rig that wont strand you on the trail with a broken suspension link.
Precision Hex Hardware
The Tactical Unit uses tough hex hardware throughout for improved strength and easy servicing.
