Unlike conventional torque-biasing differentials, Wavetrac units feature a patented internal cam device that actively maintains drive when one wheel loses load—solving the biggest limitation of traditional helical LSDs.\u003c\/p\u003e\n\u003cp\u003eIn situations where a standard torque-biasing differential would act like an open diff and send power nowhere, the Wavetrac cam mechanism generates internal load, ensuring torque continues to be delivered to the wheel with grip. The result is predictable traction, smoother power delivery, and improved performance whether on the street, track, or during aggressive driving.\u003c\/p\u003e\n\u003cp\u003eBuilt for strength and longevity, Wavetrac differentials use 9310 alloy steel gears housed in case-hardened steel bodies, secured with ARP fasteners for maximum durability. Every unit is backed by a transferable Limited Lifetime Warranty, underscoring Wavetrac’s commitment to performance and reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant Notes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAll welded OEM gear assemblies require machine work.
