ATB Limited Slip Differential

Unlike other gear diffs, the Wavetrac's patented cam device prevents the loss of drive when one axle becomes unloaded, which commonly occurs during aggressive driving, track cornering, or on slick surfaces. This ensures more predictable and consistent power delivery through corners, ultimately making the vehicle faster and more confidence-inspiring. Key performance enhancements stem from Wavetrac's patented technologies. The Carbon Fibre Bias Plate for the pinions offers consistent performance over the life of the diff, unlike other gear LSDs where pinion friction changes as the unit wears. Furthermore, the patented Wave Profile addresses driveability issues found in other ATB LSDs when near zero load conditions occur. The unit is constructed with high-strength 9310 steel gears and ARP bolts for enhanced reliability, and it is manufactured and designed in the USA. This Wavetrac differential is specifically designed for the Porsche 911 (991) models with PDK dual-clutch automatic gearboxes, including the GT3 and Turbo S variants. Confirmed fitment includes the 911 (991) 3.8 GT3 (MA1.75) from 2013-2017, various 911 (991) 3.8 Turbo S models from 2013-2020 (including variants with 560hp, 580hp, and 607hp), and the 911 (991) 4.0 GT3 (MA1.77/MDG.GA) from 2017-2020. Fitment also extends to the 911 Convertible (991) 3.8 Turbo S models from 2013-2020.
