Wavetrac differentials: modern technology for superior performance
Designed from a clean slate, the new Wavetrac Differential brings current gear technology to the market. Internally, the gear tooth shapes have been optimized for strength and better oil film retention compared to competitive designs. Our equipment package is smaller, reducing overall mass, yet more durable. Attention was also paid to the interface between side gear and shaft, providing as much material thickness as possible in this critical area - most important when power levels get high.
Wavetrac differentials are state-of-the-art differentials with helical gears, designed, developed and manufactured in the U.S. by Autotech Driveline. The Wavetrac differential is the only clutch differential on the market with patented technology that reduces wheel spin when an unloaded wheel occurs. During conditions with no axle load, the Wavetrac cam mechanism creates internal load, maintaining drive on the gripping wheel instead of behaving like an open differential (and going nowhere!).
Each Wavetrac differential is made from the highest quality materials available. The internal gears are made of high-grade 9310 alloy steel. The diff bodies are made of hardened steel. To complete the package, each Wavetrac differential is built exclusively using high-quality, high-strength fasteners from ARP, the world leader in fasteners.
All Wavetrac differentials include a transferable, limited lifetime warranty.

On some Supra/BMW models, the factory setting wheel is welded to the factory differential (also known as the center section). This kit includes labor to machine the ring gear and an ARP ring gear bolt set. Your standard rear end must be shipped to us for machining service. Drain the gear oil and remove the drive flanges before shipping. Once the ring gear is machined, we will install the Wavetrac differential in the rear end with the proper clearance specifications.
Please contact us for installation.
