Limited Slip Differential with 9310 Alloy Steel Gears

The Wavetrac differential represents modern engineering for superior performance in torque-biasing differentials. Designed and manufactured in the USA, it incorporates advanced gear tooth forms optimized for strength and improved oil film retention, while its smaller package reduces overall mass. A key innovation is its patented technology that actively mitigates wheelspin during unloaded wheel conditions. When an unloaded wheel is encountered, the Wavetrac cam device generates internal load, ensuring the gripping wheel maintains drive instead of the vehicle acting like an open differential and losing traction. The internal gears are forged from robust 9310 alloy steel, and the diff bodies are precision-machined from case-hardened steel billet. To ensure ultimate durability and reliability, every unit is assembled exclusively with high-strength ARP fasteners. This differential is designed for the Porsche 987 Cayman S and Boxster S models with the 3.4L 6-speed manual transmission, specifically for the 2006-2009 model years. It also fits the 987 Cayman R (3.6L 6MT).
