Traxxas ID Connectors
Traxxas ID Connectors
The best connectors in the industry! Secure, easy to use, high-current, also has an RFID chip that tells the charger what settings to charge it on. Now that's one smart connector.
Heavy-Duty Steel Frame Rails
Heavy-Duty Steel Frame Rails

A thick 1.5mm steel ladder frame with moulded 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. You’ll feel the difference on trails, where the elimination of chassis flex allows for precise wheel placement when navigating technical terrain.

Remote Locking Differentials
Remote Locking Differentials
Conventional crawlers equipped with axle spools sacrifice turning radius for traction. Traxxas gives you the freedom and versatility to lock and unlock both the front and rear differentials to suit your driving needs, all controlled remotely from your transmitter. Leave the differentials unlocked for relaxed driving on the trail with smooth, tight turning and better handling at high speeds. When the trail gets technical, lock the front and rear differentials, or just the front differential, for superior pull and grip over extreme terrain.
Adjustable Battery Tray
Adjustable Battery Tray

The TRX-4's main battery tray accommodates the full-length Traxxas 5000mAh 3-cell LiPo or 7600mAh 2-cell LiPo for extended run times. Securely mount full-size LiPo batteries for extended runtimes, or opt for smaller 1/16 scale Traxxas batteries for reduced weight and improved agility. The innovative hinged battery strap eliminates the need for pins, ensuring quick and secure battery changes in the field. The strap even flips to adjust for batteries of different heights. 

Torque Twist Eliminated
Torque Twist Eliminated

On conventional rigs with the limited gear reduction in the differentials, motor torque is applied to the frame to the point of twisting you right off the rocks. The TRX-4's radical portal axle design reduces the gear ratio at the wheels, virtually eliminating torque twist through the chassis. Total axle gear reduction is over twice non-portal designs, so Titan motor torque delivers smooth forward motion, not frame twist.

Titan 21T 550 Motor
Titan 21T 550 Motor

Dominate any obstacle with the TRX-4's massive Titan 21T motor. This powerhouse delivers unmatched torque to power through challenging terrain. An integrated cooling fan ensures extended runtimes and peak performance, even under heavy loads.

Experienced hobbyists will recognise the downsides in the ESC, Motor and shell choices VERY quickly. With the limited shell choices and lack of parts in Aus, I'd strongly recommend just getting a regular TRX-4, or the Sport Kit, UNLESS you can buy it with the narrow or no guard kits. The biggest challenge is trying to get everything you need in one go to play properly, especially with Traxxas treating Australia as a wet anus from space - required parts are rarer than hens teeth!
