The Ultimate Electric 4x4 Maxx Monster!
Now Includes TQ 2.4GHz Radio System!

The new Traxxas E-Maxx takes 4WD monster truck thrashing to the next level of fun and excitement. To go along with the torquey 16.8-volt EVX-2 dual-motor power system, key improvements have been engineered into the suspension, driveline, chassis, and electronics to make this the toughest, most versatile E-Maxx ever. The new E-Maxx is equipped with Revo sealed pivot ball suspension; dual-servo steering; an all-new transmission; Revo sealed differentials; a new, longer chassis; and waterproof electronics. And that’s just the start. Everywhere you look on E-Maxx Traxxas engineers have thoughtfully integrated new enhancements and features that make E-Maxx stronger, easier to use, and most importantly, more fun!
E-Maxx is equipped with sealed electronics that eliminate boundaries and let you drive where you want to drive. E-Maxx lets you blaze new trails through water, mud, snow and other wet-running conditions that wouldn’t have been possible before. Since water is no longer the enemy, E-Maxx opens up a whole new world of 4x4 adventure and fun.
The E-Maxx now includes the Traxxas TQ 2.4GHz steerwheel radio system. This new system offers the unbeatable convenience of no channels, no crystals 2.4Ghz technology, but that is just the beginning. The new TQ 2.4GHz radio is also features a built-in programmable failsafe, worry free long range control, 50/50 or 70/30 trigger neutral adjustment and the comfortable TQ case design.


E-Maxx is equipped with an all-new transmission that’s been engineered to handle nearly 2 ½ times more torque than the original, and yet do it in a more compact package. Extra-wide gears, smart use of steel components, and the Revo-Spec Torque-Control slipper all combine for the strength needed to handle the extreme power and torque that’s possible with today’s battery and motor technology. The design positions the motors closer to the chassis for a lower cg and improved handling. An optional bolt-in two-speed is available for shift-on-the-fly gearing options. Revo-Spec large diameter sealed driveshafts and sealed differentials are used for massively increased torque handling and long-lasting performance. Since the diffs are completely sealed, they can be fine-tuned with different oil viscosities to adjust the limited-slip action.

The waterproof Traxxas EVX-2 is optimized to deliver massive power from dual 7-cell battery packs. The EVX-2 packs a serious punch, belting out over 16 volts of power to the twin 550 high-torque motors. Titan 550 motors feature 30% longer motor armatures than a standard 540 size motor for monster big block torque. An internal fan helps keep the motors running at optimal temperatures for maximum power. Mash the throttle for wheelies on demand and absolutely mind-bending monster truck action that only E-Maxx can deliver. Designed by Traxxas, the EVX-2 features three drive profiles, thermal shutdown protection, and Traxxas high-current battery connectors. The EVX-2 also includes our exclusive, patent-pending Training Mode. This profile reduces the overall power output of the EVX-2 by 50% making it easier for young or new drivers to develop their control skills before unleashing full-power operation.
The chassis design is all new with 30mm of increased wheelbase for improved stability. The new battery compartments position the batteries lower, angled in towards the center of the truck for improved handling and cornering stability. The new stronger chassis braces work together with a new center skid plate to greatly enhance chassis strength and torsional rigidity.
