See How Hoss' Center Drive Delivers Maximum Traction
The Hoss 4X4 VXL’s 540XL motor delivers a high-torque kick to lift the front wheels at will and send massive clouds of dirt skyward from the Sledgehammer tires. This kind of power delivery can be tough for a drivetrain to tame, even with 4WD, but the Traxxas Torque-Biasing Center Drive is the perfect solution for delivering the best all-around driving experience. While a traditional center differential can deliver improved handling, it can also “diff out” and divert too much power to whichever end of the car has the least traction.
High-traction conditions can lead to a center differential “diffing out,” and when you’re riding a wheelie and the front wheels aren’t even on the ground, you’ll definitely see a conventional differential divert nearly all power to the front wheels. In a high-power monster truck, the tires may even grow or “balloon” due to centrifugal force. It’s tough on tires, and can make for unpredictable handling—but the Hoss beats it with Traxxas-tough tech.
Instead of an unrestricted “open” differential, the Hoss has a sealed Torque-Biasing Center Drive filled with ultra-high viscosity silicone. The factory-installed unit functions like a differential to give the Hoss smooth full-time 4WD power delivery, but it won’t “diff out” even under hard acceleration in high-traction conditions, or when you’re going for the long-distance wheelie record.
No matter what the traction level, the Torque-Biasing Center Drive Unit keeps all four Sledgehammers digging hard for maximum corner speed and precision without sudden power shifts to upset the truck’s balance or balloon the tires. You get balanced power delivery and refined handling in all conditions and on every surface, thanks to the same innovative technology proven in the X-Maxx, E-Revo VXL, and Unlimited Desert Racer—Traxxas’ most powerful models. Big horsepower? That’s easy. Getting that power to the ground? That’s engineering. With its Torque-Biasing Center Drive, the Hoss 4X4 lets you experience full Velineon brushless power with total control.
