TRX® 3.3 Racing Engine
The powerful TRX 3.3 Racing Engine is the heart of the New Revo 3.3, delivering thoroughbred race engine performance that’s absolutely second to none. The TRX 3.3 Racing Engine features a precision composite slide carburetor, PowerTune™ cooling head, dyno-proven IPS crankshaft, multi-port rear exhaust, and the starting convenience of the exclusive Traxxas EZ-Start® system. Years of testing and proven performance deliver the easiest-to-tune, most dependable, most powerful Ready-To-Race® engine available.
For the ultimate combination of torque and high-revving horsepower, we couldn’t resist taking the Extreme Power of TRX 3.3 engine to the next level by adding a dyno-tuned aluminum Revo® Resonator dual-chamber pipe and oversized Traxxas high-volume dual-stage air filter. The result is more horsepower throughout the entire powerband that you can feel and hear.
Mirror-Polish Resonator
Dual-Chamber Aluminum Pipe
The dual chamber Resonator™ aluminum pipe delivers the most broad and linear power band from the TRX® 3.3 Racing Engine. It's dyno-tuned for torque down low and big horsepower on the top end. Mirror-polish finish looks great and stays clean longer.
Large High-Volume Dual-Stage Air Filter
Engineered to work with all Traxxas air filter bases, the new extra large dual-stage air filter increases air flow to the TRX 3.3 Racing Engine. With more air intake the TRX 3.3 holds an incredibly consistent tune during long dusty mains. The dual-stage traps large particles in the outer element, while the inner element flows clean air to the engine. The large free flowing cylindrical design allows more air to get to the carburetor, which equals more horsepower!
EZ-Start® Electric Starting
Only the Traxxas EZ-Start offers the pure convenience of true one-handed operation and complete on-board, push-button electric starting. The Traxxas EZ-Start lights your glow plug and starts your engine quickly and smoothly at the push of a button. Traxxas’ exclusive Smart Start technology monitors critical starting functions, automatically sensing and diagnosing potential problems for troublefree engine starting every time! LEDs provide realtime status, even alerting you when a glow plug has failed.
150cc Fuel Tank
The new larger fuel tank increases Revo’s fuel capacity for extended run times. In addition to adding capacity and run time, the new 150cc tank is engineered to seal properly every time for consistent tuning. Like the 125cc Revo tank, this larger tank is also baffled and sumped to prevent fuel starvation.
Hard-anodized, Teflon®-Coated GTR Shocks
Ultra-long lasting hard-anodized, Teflon®-coated aluminum GTR shocks are the ultimate in off-road performance, offering silky smooth damping. Thanks to the extra tough hard-anodized finish, shock performance stays true and consistent for less maintenance and better handling.
Smooth and Durable TiN Shock shafts
Titanium Nitride coated shock shafts deliver ultra-smooth damping and the durable titanium nitride finish offers durable, smooth, long-lasting performance.
Aluminum 17mm Splined
Wheel Hub and Hex Nut
Newly designed 17mm hubs and wheel nuts provide precision alignment and unsurpassed torque handling. The all-new splined design interlocks with the new 3.8" mirror-chrome Split-Spoke wheel for a solid fit. The ground-breaking new design also accepts traditional aftermarket 17mm hex wheels. An easy-to-use molded wheel wrench is included for easy wheel removal and installation.
Large 6x13mm Outer Axle Bearings
Newly designed axle carriers utilize larger 6x13mm outer ball bearings that can handle 56% more static load and stress when compared to the stock 6x12mm Revo ball bearings. The durable, large rubber-sealed ball bearings are designed to handle hours of nitro off-road racing.
Steel Pivot Ball Retainers
New, steel retainers keep the pivot balls in place even after the most brutal crash. The new axle carrier design provides all the benefits of aftermarket aluminum carriers without the penalty in weight and cost.
Compact Receiver and Battery
Box with Integrated Personal
Transponder Mount
Borrowed from the Revo Platinum Edition, a smaller, more compact radio box accepts either 4 AA alkaline batteries or a 5-cell flat rechargeable receiver pack (sold separately). The receiver/battery box is equipped with an on/off switch and a blue-anodized antenna crimp nut. An integrated personal transponder mount adds to the clean chassis layout and is another example of the race-inspired features integrated into the New Revo 3.3.
Digital High-Torque Steering Servo
A monster truck needs a powerful steering servo for responsive performance. An included Traxxas digital high-torque, ball bearing steering servo comes standard for precision control, quick response, and unmatched torque. It has over 50% more torque than a standard high-torque servo and it's 25% faster! That's 125 oz-in torque with 0.16-second transit speed!
Four Channel Micro Receiver
A new four channel Traxxas micro receiver gives you additional room to grow! The 4-channel micro receiver features two steering servo ports, eliminating the need for a Y-harness.
Rigid Throttle Servo Mount
and Air Filter Support Bracket
The new throttle servo mount ties into the chassis to hold the throttle servo securely in place for strong braking power. Its trimmed down design is lighter and more compact than the stock throttle servo box, and the mount is also molded with an extra mounting boss for the air filter stand-off wire.
Split-Spoke Wheels with 17mm Hexes
The newly designed 3.8" Split-Spoke wheels for Revo now accept the Traxxas splined 17mm hubs for added strength, stability, and precision. Traxxas mirror-chrome Split-Spoke wheels don’t just look amazing; they are fully functional for a race track or a bash session. The horizontal bead helps grab the tire, reducing the stress placed on the glue joint by tire expansion.
3.8" Talon™ Tires
The Talon’s unique tread pattern and soft compound rubber delivers excellent grip on a variety of surfaces from pavement to off-road. The outside diameter is the same as a stock Maxx tire but the larger 3.8" wheel diameter provides responsive handling with the low-profile sidewall. Talon tires are pre-glued to Split Spoke wheels with installed foam inserts.
Blue-Anodized 3D
Semi-Monocoque Chassis
Revo 3.3 utilizes an extended chassis design that merges engineering artwork with functionality for improved stability on rough terrain. The unique monocoque chassis is cut and formed from 3mm, 6061-T6 aluminum. The engine cradle and deep channel design provide superior strength without adding unnecessary weight. An integrated chassis brace strengthens the chassis around the engine mount. A cutout below the flywheel provides flywheel access for aftermarket starter boxes.
Auto Shifting
Two-Speed Transmission
The heavy-duty forward-only two-speed is easy to adjust and delivers smooth and consistent shifts every time. A simple twist of a 2.0mm hex wrench and the shift point can be adjusted to shift earlier or later. To further the custom tuning experience, special close and standard ratio gear sets can be installed to tailor the gearing for your environment.
Torque-Control™ Slipper Clutch
The Torque-Control slipper clutch uses special semi-metallic friction material and finned aluminum alloy pressure plates to dissipate heat and provide consistent traction control. The semi-metallic friction material remains stable across a wide temperature range to provide smooth, linear engagement you can count on, tank after tank. Spur gears can be removed and replaced without altering the slipper adjustment. A center ball bearing maintains precise, long-lasting alignment with near friction-free running and virtually zero maintenance. Only Traxxas has it!
Large Diameter Disc Brake
A large 42mm steel rotor spins between two unique semi-metallic brake pads which when engaged, bind the drilled steel disc for efficient 4 wheel braking action. The proven design provides fast fade free braking to bring Revo 3.3 to a stop almost as quickly as it accelerates.
Sealed Limited Slip Differentials
The Revo 3.3 differential housings feature tunable sealed differentials with internals that offer a broad range of tuning options. Precision sealed with Traxxas X-ring silicone seals, the Revo 3.3 differentials are designed for long-lasting performance and the ability to tune for specific running conditions. Built to handle extreme torque and power, these differentials offer unmatched versatility and toughness.
Super-Duty Sealed Driveshafts
The reliable and incredibly tough Revo Drivetrain utilizes sealed super-duty driveshafts throughout the driveline. Expandable rubber seals prevent friction causing dirt from entering the half shafts. True curvilinear splines provide smooth performance and large rubber-sealed stub axle bearings are used for long-lasting, smooth running performance. Revo's sliding half shaft design is clearly superior, eliminating the metal-to-metal drive pin plunge friction that causes friction and wear in metal driveshafts and the possibility bent shafts. Plus there's no need to limit suspension travel just to keep the drive pins from popping out of the cups. Revo's driveshafts are engineered for durable, smooth, maintenance-free operation.
Sealed Pivot Ball Suspension
Traxxas exclusive rubber sealed pivot balls maintain factory smooth performance even in the harshest environments. The unique design allows easy adjustment, proven performance, and unmatched reliability. The heavy-duty axle carriers use large diameter rubber sealed bearings for ultra-smooth, and practically maintenance-free running.
Tight-Handling Progressive-2 Rockers
Optimizing Revo’s advanced suspension geometry; Progressive-2 rockers provide balanced bump absorption and chassis response for handling that can’t be matched by conventional suspension designs. For more information on the benefits of Revo's rocker-based suspension, click here.
The Most Suspension Travel
Revo architecture delivers the most suspension travel possible, tunable progressive damping rates, independent ride height adjustment, and the absolute highest level of control for any situation. The precision hard-anodized aluminum shocks are rigidly mounted to the chassis, protected from dirt, rocks, and crash damage.
4" Ground-Clearance
Revo 3.3 delivers over 4” of center ground-clearance for go-anywhere performance. Integrated skid plates protect the driveline from rocks and hard impacts.
ProGraphix® Painted Body
The extended wheelbase Revo body comes fully trimmed and painted. Decals are also applied to save time and get you driving just minutes out of the box. Traxxas' ProGraphix bodies are the hottest looking bodies around and are only available on Traxxas Ready-to-Race® models. Available in red, blue, black, and white.
Rubber-Sealed Ball Bearings
Precision rubber-sealed bearings offer the ultimate in super low-friction performance and maximum protection in dirt and nitro environments. They are used in all exposed locations on the truck and are virtually maintenance free.
