1:10 Scale 4WD Traxxas Nitro Monster Truck REVO 3.3 TRA5309 Package

Revo 3.3 takes all the award-winning innovation engineered into Revo 2.5R to a new level of power and speed. Compared to the TRX 2.5, the TRX 3.3 Racing Engine delivers 60% more peak horsepower along with an incredible boost of nearly 50% total increased horsepower under the curve. We're talking real horsepower and torque increases you will see and feel every time you hammer the throttle. There's never been an engine like the TRX 3.3 Racing Engine.

Revo 3.3 is upgraded with enhancements to harness the massive power output including 30mm of additional chassis length, increased engine mounting strength, and tighter suspension with installed progressive 2 rockers. There's also a wide-ratio two-speed inside the transmission that takes full advantage of the TRX 3.3's massive power curve for top speeds beyond 45mph! For the hardcore racer, Revo 3.3 has been designed to use the new Traxxas Revo center differential and rear brake kit (sold separately). On or off the track, Revo 3.3 is simply the ultimate, most-powerful machine for jaw-dropping handling and speed.
