Product Overview
Wavetrac® differentials are precision-engineered helical gear units designed, developed, and manufactured in the USA by Autotech Driveline. They are the only torque biasing differentials on the market featuring patented technology that actively mitigates wheelspin during unloaded wheel conditions.
When axle load drops to zero, the Wavetrac® cam mechanism generates internal load, maintaining drive to the gripping wheel—unlike conventional torque biasing differentials that behave like open diffs in such scenarios.
Each unit is built with ultra-strong 9310 alloy steel gears, enclosed in case-hardened steel bodies and secured with ARP® fasteners. All Wavetrac® differentials include a transferable Limited Lifetime Warranty.
