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.

Built To Haul

The Ultimate RC Hauler is the largest TRX-6Â model with an extra long 23.7" (603mm) wheelbase and oversize bed to haul your 4-Tec models in style. The highly detailed truck features deep gloss black paint over molded black chrome body accessories for an intimidating look to match its big rig attitude.

Detailed Bed and Lights

Adjustable wheel chocks with tie-down bands on the Ultimate Hauler’s tow bed accommodate any 4-Tec 2.0 or 3.0 model and keep precious cargo secure. A powerful and true-to-scale LED lighting system with 25 individual lights makes twilight adventures a reality.

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.
