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 BMW 335is 550i DCT 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.

★★★★★ 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.
★★★★★ Quiet as new, swapped it over in an afternoon
Mark T · Timaru · Example review Had the classic whine at 80. Diff turned up next morning, swapped it over myself with the fitting guide, return label was in the box. Three weeks on and dead quiet. Core charge came back inside a week.
Reply from the Gearhead Diffs teamCheers Mark, glad the guide did the job. Thanks for getting the core back quick.
