Wavetrac Differential, VW Audi DSG 2WD [25T RING] MK6 MK7 GTI A3/TT 2.0T 10-309-187WK
Wavetrac® diffs are state-of-the-art helical gear differentials designed, developed, and manufactured in the USA by Autotech Driveline. The Wavetrac® 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® differentials include a transferable, Limited Lifetime Warranty. ARP Ring gear bolts included (tighten to 85 ft lbs and use loctite 242).
6 Quarts of Motul Gear 300 recommended.
READ BEFORE STARTING INSTALLATION!
PARKING BRAKE TOOTHED RING DIFFERENCES:The differentials in Volkswagen 02E series dual clutch transmissions (DSG) feature a toothed ring on the body that is engaged by a claw when shifted to “park,” acting as the parking trans-brake does in automatic tranmissions.There have been two styles of this toothed ring used in the DSG over the years. The early (coarse) ones have 20 teeth, while the late (fine) ones have 25 teeth.Before fitting the Wavetrac®, verify that it has the matching toothed ring as your original differential. Do not install anything (bearings, ring gear, etc.) on the Wavetrac® before checking this!
