Wavetrac diffs are state-of-the-art helical gear differentials designed, developed, and manufactured in the USA by Autotech Driveline. The Wavetrac Differential is the only torque biasing differential on the market with patented technology that mitigates wheelspin when an unloaded wheel condition arises. During zero axle load conditions, the Wavetrac cam device acts to create internal load, maintaining drive on the gripping wheel instead of acting like an open diff (and going nowhere!). Super strong 9310 alloy steel gears are enclosed in case-hardened steel bodies, held together with ARP fasteners. All Wavetrac differentials include a transferable, Limited Lifetime Warranty. 3 1/16" case (3 1/16" bearing OD) Fits Ford 9" with 2.891" or 3.062" case. 45 degree pressure angle.

amazing product
Model: 36 Sqft
actually surprised how great the product is and way better priced then other companies. its sticky and also has thickness enough to cover metal parts on cars. i would recommend 100% just ordered another 18ft for the rear deck and to have some extra! does not smell. easy to install and helps stop vibration.
