Helical Gear Differential

The Wavetrac Differential 8.8 inch 31-Spline SVT Cobra 2003-4 IRS is a performance differential engineered for superior traction and acceleration. It utilizes advanced helical gear technology, with internal gear tooth forms optimized for strength and improved oil film retention. The design prioritizes durability, especially at the critical side gear/axle interface, making it suitable for high-power applications. This differential is distinguished by its patented ability to maintain drive during zero axle load conditions, preventing the wheelspin common with open differentials. During such instances, the internal cam device generates load, ensuring the gripping wheel continues to receive power. This results in enhanced performance during acceleration and cornering by effectively driving both wheels. Constructed with the highest quality materials, the Wavetrac Differential features internal gears made from high-strength 9310 alloy steel and a diff body machined from case-hardened steel billet. It is assembled exclusively with high-strength ARP fasteners. All Wavetrac differentials come with a transferable, Limited Lifetime Warranty. Intended applications include the Ford SVT Cobra 2003-2004 IRS model. It is also noted as a beneficial 31-spline solution for vehicles utilizing c-clip eliminators or full-floating rearends.
