X-Monster MT 8S Ready to Run Chassis (No Body Included) (TRA77036-4-WB)

The X-Maxx MT Chassis delivers the ultimate in monster truck performance, combining legendary X-Maxx toughness with new levels of strength, size, and style. Powered by 8s LiPo capability and built on the most advanced X-Truck platform to date, the X-Maxx MT Chassis is ready to unleash over 30 volts of extreme power for blistering acceleration and speeds over 50 mph. Designed to accept a range of replica monster truck bodies, it provides an authentic scale look along with unstoppable performance on any terrain.

This chassis is equipped with massive 8.6-inch Terra Groove tires featuring a chevron tread pattern for superior grip on dirt, sand, and pavement. The belted construction prevents ballooning at high speeds, while the ultra-soft rubber compound ensures maximum traction and control. The heavy-duty suspension arms include double-shear connections and captured hinge pins for enhanced durability, even in the harshest conditions.

The X-Maxx MT Chassis is compatible with a variety of clipless monster truck bodies (sold separately), including officially licensed Ford F-150, Chevrolet C/K, and BIGFOOT No. 8 options. These bodies include reinforced full-length inner cages for added rigidity and durability. The chassis also accepts existing X-Maxx clipless bodies without modification.

A powerful 2085XL metal-gear steering servo delivers 450 oz-in of torque, ensuring sharp, responsive handling even with the oversized tires. Chrome-finished energy-absorbing bumpers provide impact protection while enhancing the truck’s aggressive scale appearance. Reinforced HD output yokes, taken from Pro Scale Sand Car technology, offer unmatched drivetrain strength.

Optional whip lights (sold separately) can be mounted to the new X-Monster replica bodies for increased visibility and scale realism. With its unmatched blend of rugged design, extreme power, and monster truck styling, the X-Maxx MT Chassis sets a new benchmark for RC monster truck performance.
