Wavetrac Differential Audi 80/90/UrS4 QUATTRO REAR

Wavetrac® Limited Slip Differential Overview
Wavetrac® differentials are state-of-the-art 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 diffs that behave like open differentials in such scenarios.

Each unit is built with ultra-strong 9310 alloy steel gears housed in case-hardened steel bodies and secured with ARP® fasteners. All Wavetrac® differentials include a transferable Limited Lifetime Warranty.

Note: Includes bearing spacer for the small-end side of the differential (opposite the flange end), sized 60mm x 45.3mm x 3.2mm. Spacer is not required on all models.
