Limited Slip Front Differential for 02E S-Tronic

It features a patented design that mitigates wheelspin during unloaded wheel conditions by creating internal load, ensuring consistent drive to the gripping wheel. This is achieved through precisely engineered, converging/diverging wave profiles on the side gears that automatically increase the bias ratio when needed and seamlessly revert to the nominal ratio for optimal drivability. Constructed in the USA, this differential utilizes high-strength 9310 alloy steel for its internal gears and is machined from case-hardened steel billet for the body. It exclusively uses high-strength fasteners from ARP. The Wavetrac differential also offers interchangeable friction plates, sold separately, allowing users to fine-tune the bias ratio using different materials to match specific performance needs. This limited slip differential includes ARP ring gear bolts and requires 6 quarts of VW Audi DSG oil. It comes with a transferable Limited Lifetime Warranty. **Important Fitment Note:** This differential is designed for 02E DSG transmissions with a 20-tooth (coarse) ring. It is crucial to verify that your original differential has the matching 20-tooth ring, as a 25-tooth (fine) ring was also used in some DSG models. Do not install any components before checking this compatibility.
