Introducing the TRX-4 Tactical Unit — Traxxas have been working hard on this new tough-looking body combined with Traxxas's proven TRX-4 1/10 RC crawler chassis. The TRX-4 RC Truck is packed full of features right out of the box: remote differential locks, remote high and low gearing at the flick of a switch, portal axles, inner fenders, waterproof electronics, metal geared high torque steering servo, and aluminium shocks.

Remote Locking Differentials — the TRX-4 has differentials you can lock from your remote controller. No need to break from the action — just flick a switch on the fly.

Portal Axles — the first rock crawler to have the extra ground clearance that axle portals provide. Go where others can't.

High/Low Transmission — drive to your next crawling challenge in high gear, then flick the rocker switch to engage low range and conquer tough terrain with exceptional torque.

Micro Cables — the TRX-4 uses three fully-waterproof micro servos to actuate the front and rear differentials as well as the high/low range selection on the transmission. Sleeved micro cables eliminate complicated linkages that would otherwise limit suspension articulation.

Traxxas ID Connectors — secure, easy to use, high-current connectors with an RFID chip that tells the charger what settings to charge on.
