Audi Performance Parts: Wavetrac® Differential Type Audi 2WD DSG S-tronic 20T ring (10.309.185WK)

Wavetrac® Differential is designed specifically for Audi A3 FWD S-tronic DSG models. Designed from a clean sheet, the new Wavetrac® Differential brings current gear technology to the market. Internally, the gear tooth forms for the Wavetrac® Differential are optimized for strength and improved oil film retention over competitive designs. The Wavetrac® Differential Type 02Q gear package is smaller, reducing overall mass, yet is more durable. Attention was also paid to the side gear/axle interface, putting as much material thickness as possible in this critical area - most important when power levels get high. Each Wavetrac® Differential is crafted from the highest quality materials available. The internal gears are made from high strength 9310 alloy steel. The diff bodies are machined from case hardened steel billet. To complete the package, every Wavetrac® differential is built exclusively using high quality, high strength fasteners from ARP®, the world leader in fastener technology.
