Review TORQUE SOLUTION Audi Billet Rear Differential fits S4 S5 2008–2017
The Torque Solution TS-RDi-860 is a high-performance billet rear differential designed specifically for the 10-17 Audi S4 and S5 models (2008-2017). This differential is a testament to Torque Solution's commitment to delivering superior quality and performance for automotive enthusiasts.
The TS-RDi-860 is an upgrade from the stock differential, offering enhanced torque capacity and improved traction. It is engineered with a robust billet construction, ensuring durability and reliability under high-stress conditions. The differential case is precision-machined from a solid block of 6061-T6 aluminum, offering a significant weight reduction compared to the heavier cast iron OEM differential.
The TS-RDi-860 features a robust 31-spline output shaft, which is a significant upgrade from the stock 23-spline shaft. This upgrade provides increased strength and durability, allowing the differential to handle higher torque loads. The differential also comes with 4.10 gears as standard, which are ideal for track use and provide a balanced combination of acceleration and top speed.
The TS-RDi-860 is also equipped with a Quaife ATB (Automatic Torque Biasing) limited-slip differential. This advanced technology provides superior traction and stability, especially during cornering and acceleration. The ATB differential uses a series of clutch packs that engage and disengage based on the torque distribution between the wheels, ensuring optimal traction and preventing wheel spin.
The Torque Solution TS-RDi-860 is a plug-and-play upgrade, meaning it fits directly onto the car without any modifications. It comes with all necessary hardware for installation, and a detailed instruction manual is provided for easy installation. This differential is a must-have for Audi S4 and S5 owners who demand superior performance and reliability from their vehicles.
In summary, the Torque Solution TS-RDi-860 is a high-quality, billet rear differential designed for the 10-17 Audi S4 and S5 models. It offers enhanced torque capacity, improved traction, and superior durability, making it an ideal upgrade for track use and daily driving. With its plug-and-play design and advanced Quaife ATB limited-slip differential, the TS-RDi-860 is a performance upgrade that delivers unmatched performance and reliability.
