About the Wavetrac differential

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 Mustang S550 EcoBoost 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.

★★★★★ Exactly as described
Sarah M · Dunedin · Example review

Price was the price, no surprises. Return pickup was already booked which made life easy.

★★★★★ We fit these for customers every month
Workshop customer · Christchurch · Example review

Order before 2pm, on the bench next morning. Preload sorted so we do not see them back. Saves us a hoist for a week every time.

★★★★★ Sorted the clunk
Dave P · Nelson · Example review

Rang the team first to check it was the right one for my rego. It was. Fitted by my local mechanic, no more clunk on take off.
