Wavetrac designed this differential from a clean sheet, so it brings current gear technology to the market. Internally, the gear tooth forms give more strength and better oil film retention than competitive designs. The gear package is also smaller, which reduces overall mass yet makes it more durable. In addition, Wavetrac put as much material as possible at the side gear and axle interface, because this area matters most when power levels get high.
The Wavetrac Ford 9 inch 33 spline unit uses patented technology that mitigates wheelspin when an unloaded wheel condition arises. In fact, it is the only torque-biasing differential on the market that does this. During zero axle load conditions, the Wavetrac cam device acts to create internal load. As a result, it maintains drive on the gripping wheel instead of acting like an open diff and going nowhere.
Wavetrac crafts each differential from the highest quality materials available. The internal gears use high-strength 9310 alloy steel, and the diff bodies come from case-hardened steel billet. To complete the package, every Wavetrac differential uses high-strength fasteners from ARP, the world leader in fasteners. Finally, all Wavetrac differentials include a transferable limited lifetime warranty.
