Limited Slip Front Differential for 02E S-Tronic DSG 25T

The Wavetrac Limited Slip Front Differential is engineered to provide enhanced acceleration and faster cornering for compatible front-wheel drive vehicles with the 02E S-Tronic (DSG) 25T Ring Transmission. Its patented design automatically improves grip in low traction conditions by increasing the bias ratio as a function of load, offering improved no-load performance that surpasses other helical gear differentials. This feature provides a higher bias ratio when needed without detriment to the car's handling. Constructed from high-strength 9310 alloy steel gears within a case-hardened steel billet body, this differential is built for durability and longevity. It utilizes exclusively made, high-strength ARP® fasteners and features an optimized gear tooth form for strength and improved oil film retention. The internal gear package is smaller and more durable, with added material thickness at the critical side gear/axle interface. It comes standard with carbon-fiber bias plates for optimal performance, but its behavior can be further tuned using separately sold interchangeable friction plates with different friction coefficients. This customization allows users to fine-tune the differential's response based on applied torque load. Fitment includes: - 2006 - 2012 Audi A3 FWD S-Tronic DSG (8P) - 2006 - 2012 Audi TT FWD S-Tronic DSG (MkII - 8J) - 2006 - 2009 Volkswagen Golf/GTI DSG (MkV) - 2010 - 2014 Volkswagen Golf/GTI DSG (MkVI) - 2006 - 2009 Volkswagen Jetta/GLI DSG (MkV) - 2010 - Present Volkswagen Jetta/GLI DSI (MkVI) A critical note for installation: The differentials in Volkswagen 02E series DSG transmissions have either a 20-tooth or a 25-tooth ring. Before installation, it is essential to verify that this Wavetrac differential's 25-tooth ring matches your original differential. Do not install any other components until this verification is complete.
