4x4 monster truck fun starts with T-Maxx. When T-Maxx launched onto the scene a whole new world of R/C driving possibilities emerged. T-Maxx has become the world's best-selling Ready-To-RaceŽ nitro monster truck by climbing, jumping, and ripping through terrain that others simply wouldn't dare to attempt. Hardcore nitro monster crushing continues to evolve and so does T-Maxx. Introducing the new T-Maxx 3.3. This brutal new Maxx responds to the call with a huge new stance; a tougher backbone; and wicked, tire-searing performance. T-Maxx brings it all together and unlocks a whole new level of monster thrashing potential. Go faster, jump higher, and let your creativity find new forms of torturous off-road pounding. The new T-Maxx is stronger, bigger, and meaner right down to its monster core. Maxx-Sized Stance The new T-Maxx 3.3 is the biggest Maxx ever. New, giant Maxx tires deliver massive grip off-road and at 6.3" tall, they add increased ground clearance to gobble up deep ruts and overcome huge boulders (be sure to check out the videos!). In the city, urban obstacles such as curbs and stairs beckon for an all-out Maxx assault. Maxx tires come pre-glued to 3.8" Mirror-Chrome Hurricane wheels. Traxxas engineers equipped the new T-Maxx 3.3 with an extended wheelbase (30mm longer) for maximum stability. T-Maxx is able to put more power the ground for even more acceleration and amazing directional control. There's no skimping when it comes to the chassis. It's formed from 4mm thick 6061-T6 aluminum and then anodized in brilliant blue. Meaty new chassis braces and an all-new skid plate add rock-solid rigidity. More Power! The TRX 3.3 Racing Engine is famous for its broad, linear output that makes Extreme Horsepower available practically anywhere in the rpm range. Hammer the throttle at any speed and the T-Maxx completely shreds the ground underneath. Brutal bottom-end torque rips massive wheel-standing launches that swell to top speeds soaring past 45mph! The new extra-large dual-stage Traxxas air filter allows increased air flow to the TRX 3.3 Racing Engine, breathing in even more horsepower and torque. Larger filtering capacity also delivers consistent tuning during long running sessions and between maintenance intervals. At the opposite end, the Resonator dual-chamber Maxx pipeprovides an average peak torque increase of 16% over the standard Maxx pipe, and a 10% increase in total power across the whole range. Full mirror polish adds that final touch.
