Overview

It features a patented technology that mitigates wheelspin during unloaded wheel conditions by creating internal load to maintain grip on the driving wheel. The internal gears are constructed from high strength 9310 alloy steel, and the diff bodies are machined from case-hardened steel billet. This differential is built using high-strength ARP fasteners.
Show original supplier description
The Wavetrac Differential is a state-of-the-art helical gear differential designed, developed, and manufactured in the USA by Autotech Driveline. Its unique patented technology mitigates wheelspin when an unloaded wheel condition arises. During zero axle load conditions, the Wavetrac cam device acts to create internal load, maintaining drive on the gripping wheel instead of acting like an open differential. This makes it ideal for high-performance road cars that see track use, offering a balance of strength and driver transparency. Each Wavetrac Differential is crafted from the highest quality materials, including internal gears made from high strength 9310 alloy steel and diff bodies machined from case-hardened steel billet. All Wavetrac differentials include a transferable, Limited Lifetime Warranty.
