TRX® 2.5 Racing Engine
"The TRX 2.5 blows away every other small block engine we've ever tested!" – RC Nitro Magazine.
Readers' Choice award for Best Nitro Engine. – RC Car Action Magazine
Where Power Meets Technology® The TRX 2.5 Racing Engine is nothing short of amazing. It comes loaded with all the hottest performance goodies. The two-needle composite slide carburetor, trick porting, and free-flowing rear exhaust deliver unmatched, class-leading horsepower that rips huge wheelies and pushes the Nitro Rustler past 50mph! Plus only the TRX 2.5 has the push-button starting convenience of the EZ-Start® Electric Starting System.
Precision 2.4GHz Control
With the TQ 2.4GHz radio system, you just switch on and drive. There are no channels or frequencies to manage, so the focus is on having fun. The TQ’s ergonomic design is comfortable for all-day driving, and its sleek lines are enhanced by an internal antenna that is impervious to damage. To customize the Nitro Rustler’s controls, the transmitter’s factory servo directions can be easily reversed through the simple programming system.
High-Volume Air Intake System
The TRX 2.5 Racing Engine uses a high-volume air intake system with a two-stage air filter. The filter housing and neck are designed to mate seamlessly with the carburetor to eliminate turbulence in the air-flow going into the engine.
Tuned Exhaust System
Nitro Rustler's tuned exhaust system increases the engine's power output for maximum torque and incredible top speed. It also promotes cooler running and better fuel efficiency.
EZ-Start® Electric Starting System
There's no penalty to pay for having more power either. The TRX 2.5 Racing Engine is equipped with EZ-Start push-button electric starting and simple, reliable tuning from the two-needle composite slide carburetor. Plus it's backed by the support and reliability you expect from Traxxas including the Exclusive Traxxas Power Up Plan.
Fiber-Composite / 6061-T6 Aluminum Chassis
An upper, fiber-composite chassis deck stabilizes the fuel tank and ties in to the 6061-T6 lower aluminum chassis. The dual-plane design increases chassis rigidity allowing the suspension to effectively soak up the bumps. The blue-anodized aluminum chassis acts like a heat sink to draw additional heat away from the engine, plus it features countersunk screw holes to prevent speed-robbing drag.
Alias™ 2.8" Pre-Glued Tires with Foam Inserts
The Nitro Rustler comes with the impressive 2.8" Twin-Spoke™ mirror-chrome wheels. Alias™ rear tires with a Step-Pin design, and wrapper with Alias ribbed tires up front.
The Twin-Spoke wheels feature a lightweight horizontal bead that holds the tire to the rim even under extreme rpm. Performance-designed foam inserts are standard and all tires come pre-glued from the factory to get you rolling right out of the box.
New Body, New ProGraphix® Paint Scheme
The Nitro Rustler's fully trimmed and painted ProGraphix body is available in two variatons of red and blue. Decals are also applied to save you time and get you driving just minutes out of the box. Traxxas' ProGraphix bodies are the hottest looking bodies around.
Powder Coated White Springs
New white springs feature long-lasting white powder coated finish.
High-performance bellcrank steering system minimizes bump steer to increase cornering stability.
Call it a factory 'works' pipe. The pipe length and shape are dyno-tuned for the TRX 2.5 to bring out the most power over the broadest RPM range. All that means is you can nail the throttle hard at any speed and get some serious 4-wheel roost.
Adjustable Slipper Clutch
The slipper clutch on the Nitro Rustler is fully adjustable to control the power output to the rear wheels for increased traction control on a wide variety of surfaces. It also protects the transmission during high-impact jump landings.
High-Torque Steering Servo
A high-speed stadium truck needs a powerful steering servo for responsive performance. An included Traxxas high-torque steering servo comes standard for enhanced steering authority and reliability.
Oil-Filled Ultra Shocks™
Nitro Rustler's advanced oil-filled Ultra Shocks utilize X-ring technology for a perfect seal and super-smooth performance. They are fully tunable with a wide range of oils, springs, and pistons. Features include pressure bladders for air/oil separation and spring clips to precisely change the ride height and spring pre-load. They can be renewed in minutes with our inexpensive shock rebuild kits.
Magnum 281™ Transmission
The Nitro Magnum 281™ single speed transmission is built Nitro Tough™ with 32 pitch gears, metal top gear, and smooth-running, long-lasting precision ball bearings. This proven, track-tested, three-gear design is built for performance driving applications.
Planetary Gear Differential
The Traxxas planetary gear differential uses hardened steel internal gears for maximum strength during rigorous off-road racing. This type of differential requires virtually no maintenance and its efficient design puts maximum tire-shredding power to the wheels.
Fiber Composite Arms
Durable fiber composite arms are extra tough to take the off-road pounding we know you'll put Nitro Rustler through. Captured rod ends on the metal turnbuckles provide unmatched durability and they simply won't pop off.
Telescoping U-Joint Driveshafts
Slider driveshafts are extremely durable, and they allow greater articulation for increased suspension travel.
