About the X-Maxx Ultimate 8S

Premium Materials & Rugged Drivetrain

Constructed with 6061-T6 aluminum components, including C-hubs, steering blocks, motor mounts, and differential housings, the X-Maxx Ultimate is engineered for strength and durability. It’s 8s capable drivetrain includes hardened steel gears, CV driveshafts, splined aluminum center driveshafts, and sealed differentials filled with silicone fluid for smooth power distribution. A Torque-Biasing Center Drive™ helps absorb shocks and maintain traction under extreme loads. The fixed motor mounting system ensures precise gear mesh without manual adjustment, while the composite chassis design interlocks for added rigidity and protection from dirt and debris.

Suspension, Steering & Clipless Body

With GTX™ aluminum shocks, double-shear suspension points, and 7075-T6 toe links, the X-Maxx Ultimate provides unmatched suspension travel and durability. Steel pins, sealed bearings, and a rugged steering system with a 2085RL high-torque metal gear servo deliver sharp handling and reliability. The innovative clipless body mount system enables quick, one-handed removal using a pivoting rear latch, eliminating the need for body clips while reinforcing structural strength. Integrated nerf bars and energy-absorbing bumpers add further protection for aggressive driving.
