Wavetrac® diffs are state-of-the-art helical gear differentials designed, developed, and manufactured in the USA by Autotech Driveline. The Wavetrac® Audi A4 & S4 Quattro Differential is the only torque biasing differential on the market with patent-pending technology that mitigates wheelspin when an unloaded wheel condition arises. During zero axle load conditions, the Wavetrac cam device acts to create internal load, maintaining drive on the gripping wheel instead of acting like an open diff (and going nowhere!). Super strong 9310 alloy steel gears are enclosed in case-hardened steel bodies, held together with ARP® fasteners. All Wavetrac® rear differentials include a transferable, Limited Lifetime Warranty.
*Includes bearing spacer for small end side of the differential, only needed on some models
Fits B5 A4/S4/RS4 (quattro) and B6/7 A4/S4 (quattro). Does not fit B7 RS4.
