The 2025 X-Maxx Ultimate goes even further with new bold graphics, upgraded axles, and our most powerful steering servo. Don’t miss your chance to own the Ultimate monster truck!
Ultimate Durability
How do you improve the toughest truck ever to wear the Traxxas name? You add aluminum—lots of aluminum! X-Maxx Ultimate receives substantial aluminum upgrades in all key areas of performance: suspension, chassis, drivetrain, and steering to usher in a new era of strength and durability.
Included Wireless Module
A Traxxas Link™ Wireless Module comes standard on X-Maxx Ultimate to take full advantage of its on-board telemetry. The free Traxxas Link app allows you to make micro-adjustments to the transmitter and view real-time telemetry data like speed, RPM, and battery voltage on your mobile device.

See all the high-performance upgrades that transform X-Maxx into the ultimate 8s tough truck.
TQi™ Transmitter with Wireless Module
With 50+ mph of 8s power on tap, X-Maxx Ultimate needs maximum precision and control. X-Maxx Ultimate’s factory-installed Wireless Module adds powerful TQi tuning and telemetry tools on your mobile device. Use the free Traxxas Link™ app to control steering and throttle sensitivity; steering percentage; braking strength; and throttle trim by simply touching and dragging the sliders on the high-definition graphic interface.
Unique ProGraphix Body
X-Maxx Ultimate comes with a unique body and graphics to set it apart from the pack. Tough body reinforcements and a rigid internal frame provide extra protection during rollovers to keep your body looking fresh even longer.
Aluminum GTX™ Shocks
X-Maxx Ultimate adds ultra-smooth TiN-coated shafts, color-matched aluminum shock caps, and threaded adjustment rings to its proven GTX shocks. GTX shocks soak up massive bumps to smooth out the roughest terrain. Their large oil volume dissipates heat for all-day shredding while an integrated wiper seal keeps the shafts clean.
Belted Sledgehammer Tires
In addition to their high-speed performance, belted Sledgehammer tires deliver extreme traction and control on a variety of off-road surfaces. At 8.4" tall, Sledgehammer tires give X-Maxx Ultimate a more powerful stance with increased ground clearance. The tires’ open block tread design won’t clog up with mud and debris for unmatched traction in loose surfaces.
Factory-Installed Telemetry
Factory-installed telemetry sensors collect and record X-Maxx Ultimate’s telemetry data as you drive. Add the free Traxxas Link app to your mobile device to view real-time speed, RPM, temperature, and battery voltage data. The full-color dashboard is fully customizable with up to nine different dial or digital readout gauges.
Aluminum Differential Housings
Front and rear machined aluminum housings eliminate flex to keep X-Maxx’s huge differentials in perfect alignment jump after bone-crushing jump. The housings are milled from high-grade 6061-T6 aluminum for maximum strength and protected by a brilliant anodized finish.
Aluminum Caster and Steering Blocks
X-Maxx Ultimate’s caster and steering blocks combine the brute strength of 6061-T6 aluminum with carefully engineered steering and suspension geometry. The brilliant anodized finish adds high-tech style with laser-etched logos to show off your genuine Traxxas performance parts.
TUBES Toe Links
Adjustable TUBES toe links make it easy to dial-in the perfect settings for greater precision and control. TUBES are lighter than steel and stronger than titanium with a unique hollow tube design which maximizes rigidity while reducing weight. Made from ultra-high-grade 7075-T6 aluminum, TUBES feature a brilliant, anodized finish for extra style.
Precision Steering
Machined from tough 6061-T6 aluminum, X-Maxx Ultimate’s ultra-rigid bellcrank assembly drastically enhances steering precision and strength. Tight tolerances and a servo saver bushing allow the bellcranks to pivot smoothly on sealed ball bearings with a heavy-duty servo saver spring for added protection.
High-Torque Metal Gear Servo
Turning X-Maxx Ultimate’s huge 8.4" Sledgehammer tires is the ultra-powerful 2085RL metal-gear servo. With 650 oz-in of torque, X-Maxx Ultimate has extra power on tap for extreme driving on any surface. An aluminum double-shear servo horn eliminates flex for fast, responsive steering at high speeds.
Aluminum Motor Mounts
High-strength aluminum motor mounts and washers lock the massive 1200XL Big Block motor firmly into place to keep the gears perfectly aligned even on the biggest jumps. The mounts utilize the standard truck’s keyed gear mesh system for easy and precise adjustments.
Machined Pinion and Spur Gears
X-Maxx Ultimate features a pinion and spur gear machined from hardened steel for maximum power handling and durability.
Aluminum Transmission Cover
The aluminum transmission cover is color-matched to the truck with a laser-etched logo for extra style. Carefully milled from 6061-T6 aluminum, the cover locks in the chassis tightly to keep the transmission gears in perfect alignment. It also works perfectly with the 7886 high-speed overdrive gear set for extreme speed runs.
Ultra-Heavy-Duty Driveshafts
Developed for the two-wheel-drive Pro Scale Sand Car, these driveshafts are the toughest ever fitted to a Traxxas vehicle. New beefed-up differential output yokes are the largest in the X-Truck lineup. Power feeds to 17 mm splined aluminum axles through steel CV driveshafts to maximize suspension travel and durability.
Aluminum Hub Carriers
6061-T6 aluminum stub axle carriers add both strength and beauty to X-Maxx Ultimate without compromising its carefully tuned suspension geometry.
Aluminum Wheelie Bar Wheels
Aluminum wheelie bar wheels add brilliant eye-catching style to the already outrageous X-Maxx Ultimate. Outfitted with aluminum axles and sealed ball-bearings, the wheels feature durable soft-compound tires to help harness X-Maxx’s brutal horsepower as it wheelies for days.
