Overview

The Wavetrac differential is a state-of-the-art helical gear differential designed for the Audi 01E transmission. It features patented technology to mitigate wheelspin during unloaded wheel conditions by creating internal load on the gripping wheel. The internal gears are made from high-strength 9310 alloy steel, and the diff bodies are machined from case-hardened steel billet, utilizing ARP fasteners.
Show original supplier description
The Wavetrac Differential is a modern helical gear differential engineered for superior performance in Audi 01E transmissions. Designed with current gear technology, its optimized gear tooth forms enhance strength and improve oil film retention, while the smaller, more durable gear package reduces overall mass. Critical attention has been given to the side gear/axle interface, maximizing material thickness for high power levels. The Wavetrac's patented cam device generates internal load when axle load is zero, ensuring continuous drive to the gripping wheel. The Wavetrac Differential is designed for Quattro models including the Audi B5 S4 & C5 A6 2.7T, and Audi 4.2L C5 A6 & A8 6-speed transmissions. It comes with a transferable, Limited Lifetime Warranty. Ring gear bolts are not included but can be reused.
