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 patent-pending 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.

 

Installation Note
Some models may require longer ring gear bolts than stock.
