Show original supplier description
The Wavetrac Differential is a high-performance helical gear differential engineered and manufactured in the USA. A key feature is its patented technology that actively creates internal load during zero axle load conditions, preventing wheelspin and maintaining drive on the gripping wheel, unlike an open differential. ARP fasteners are used throughout the assembly, ensuring reliability under high stress. The differential is designed for the HAG215 rear axle and is compatible with various Mercedes-Benz AMG models, including the E55/E63 W211, E63 W212, C63 W204, C55 W203, SL55/SL65 R230, CLS63, SL600 R230, CLK63/CLK55/CLK500 ('04+) W209, and SLK55 R171. The differential ring gear bolt torque specification is 75 ft-lbs. All Wavetrac differentials come with a transferable, Limited Lifetime Warranty, reflecting the manufacturer's confidence in their product's durability and performance.
