Bigger gears. More steel. Basically bombproof.

Sledge channels explosive 6s brushless power through a properly sized all-steel driveline that is engineered for maximum strength and long life. Massive steel gears and proven 4-gear differentials transfer the power to high-strength steel driveshafts. Smooth-running CV joints are used in front and the center shafts feature greased and boot-protected drive cups for cool-running, long-lasting performance. It's Sledge's superior design and properly sized all-steel driveline that lets you forget about durability worries and focus on dirt-roosting launches, sky-high jumps, and all-out speed runs.

Torque-Biasing Center Drive
Traditional 1/8 scale center differentials are easily overwhelmed by 6s power and “unload” to the front wheels when accelerating. Sledge doesn't have that problem. Sledge's Torque Biasing Center Drive is filled with ultra-thick silicone fluid and robust gears to distribute power evenly to all four wheels. This helps to eliminate tire ballooning and keeps you in control. The center drive’s steel spur gear, reinforced case, and four steel spider gears ensure long-term strength and reliability with 6s LiPo power.

Steel Driveshafts Throughout
Sledge’s center and outer driveshafts are all solid steel to withstand brutal 6s power no matter how hard you drive, even in high-traction conditions and rough terrain. The center drive cups are protected by rubber boots on the joints to seal grease in and keep dirt and debris out.

Steel Gear Differentials
Sledge uses true 6s differentials to handle its ferocious power. Sledge’s ring and pinion gears are over 20% larger and 75% thicker than traditional 1/8 components for lasting performance. Inside the differential’s reinforced case, four steel spider gears and high-viscosity silicone fluid provide the perfect balance of strength and performance for true 6s power.
