Traxxas TRX-4 Sport 1/10 Scale Trail Rock Crawler Assembly Kit

TRX-4 Sport Innovation and Off-Road Capability Now Available as a Kit!

The Traxxas TRX-4 Sport is purpose built for trail-conquering RC fun with innovative technical features and rugged durability. The new TRX-4 Sport Unassembled Kit combines all the technical capability of the RTR truck, with the excitement of building your own kit. The TRX-4 Sport Kit assembles to form a roller chassis without electronics, battery, or charger. From mild to wild, enjoy ultimate build-it-yourself freedom to add your own motor, electronic speed control (ESC), servo, and radio system to the highly competent chassis. All the parts are organized neatly in labeled bags with pre-assembled shocks and suspension links. A fully illustrated color manual makes the kit as much fun to construct as it is to take off-road.

The Traxxas TRX-4 Sport Kit comes fully outfitted with an entire complement of scale accessories as standard equipment. The expedition rack not only looks great, but provides rugged protection for the body. The body and expedition rack are outfitted with a replica snorkel, side mirrors, traction boards, fire extinguisher, jack, and gas cans for maximum scale detail. The front and rear injection molded grill and tail gate also include lenses to make installing LED lights a breeze!

In-Depth Features:

The Power of Portals
Build your own game-changing TRX-4 portal axles with the TRX-4 Sport Kit. These innovative axles lift the chassis at the wheels for huge center pumpkin ground clearance. In order to achieve the same clearance with straight axles (and not get stuck) your tires would need to be over an inch taller than the TRX-4’s. Straddling boulders with ease, the TRX-4 chassis takes the path less traveled and leaves everything else behind.

Torque Twist Eliminated 
Total axle gear reduction with portals is over twice non-portal designs, virtually eliminating torque twist. Portal axles transform the motor’s power into straight, powerful, forward motion without twisting you off the rocks.

Canyon Trail 1.9 Tires 
The 1.9 Canyon Trail tires and tuned foam inserts are super-soft and grippy to deliver superior bite on rocky surfaces with convincing scale realism. A 12mm steel hex drives the wheels.

Pre-Assembled Aluminum GTS Shocks 
Pre-assembled coil-over GTS shocks deliver silky-smooth damping performance and feature threaded shock bodies, an O-ring cap seal, and dual X-ring shaft seals. Just add the included shock oil.

Pre-Cut Clear Body
The TRX-4 Sport’s clear body comes pre-cut and ready to mount. The included window masking makes it easy to customize the body with your own polycarbonate paint. The detailed injection-molded grill and tail gate are LED-ready with clear (front) and colored (rear) lenses.

Expedition Rack and Scale Accessories
The TRX-4 Sport Kit includes rugged high-clearance front and rear bumpers with red D-rings and matching differential covers. The included Expedition Rack includes a full complement of replica accessories including a jack, gas cans, shovel, axe, snorkel, fire extinguisher, spare tire mount, and traction boards.

Locked Differentials
Full-time locked front and rear differentials transform your motor’s torque into unstoppable climbing action. With no slippage possible, all four wheels claw with equal traction, powering the lightweight Sport over the toughest obstacles.

Steel Gear Transmission
The single-speed transmission is geared low for the raw torque required to scale the steepest grades. Steel gears provide the Traxxas-Tough^™ durability that keeps you on the trail.

Extreme Capability
Steep approach angles front and rear allow the TRX-4 Sport to tackle big obstacles head on. The front motor design biases weight forward for superior climbing ability.

Improved Geometry
Portal axles raise the axle link mounts, center driveshaft, steering drag link, and the tie rod up and out of harm’s way. Center ground clearance is increased while critical driveshaft and suspension link angles are reduced.

Tough, Pre-Assembled Suspension 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 won’t strand you on the trail with a broken suspension link.

Waterproof
The TRX-4 Sport Kit includes a fully waterproof receiver box for your receiver (sold separately). Only Traxxas’ patented innovation gives you the freedom to tackle creeks, snow, and mud without worrying about water in your electronics.

Rigid Steel Frame
A heavy-duty formed-steel ladder frame with molded cross members creates an extremely rigid backbone. The elimination of chassis flex allows for precise wheel placement when navigating technical terrain.
