Ultimate RC Hauler

One look at the new TRX-6® Ultimate RC Hauler and you’ll know this truck means business. Based on the hugely capable TRX-6 platform, the RC Hauler is the biggest and baddest rig in the TRX lineup. The tough looks are backed up with even tougher performance. The rear bed features adjustable wheel chocks and tie-down bands to haul and display 4-Tec® models with style. A highly detailed LED lighting system and black-over-black chrome body accessories give the Hauler a tough, menacing look. The Ultimate RC Hauler is built Traxxas Tough with portal axles, high/low transmission, and T-Lock remote locking differentials. When you’re ready for big-scale RC fun, nothing comes close to the Traxxas Ultimate RC Hauler.

TRX-6 Capability

TRX-6 Capability

Built on the supremely capable TRX-6 platform, the Ultimate RC Hauler uses six drive wheels to get into the action with trail-conquering grip of three remote-locking T-Lock differentials to get back out. A remote-shifting high/low range transmission amplifies the motor’s torque down low to move heavy loads while still providing ample cruising speed when unloaded.
TRX-6 Capability

Factory-Installed Pro Scale® Winch

The Ultimate RC Hauler now includes a Traxxas Pro Scale Winch standard, raising the scale realism to a new level. Utilize the winch to pull and secure your 4-Tec models onto the Hauler's detailed bed with the included remote. The winch is pre-wired and ready to go out of the box.
