Fits:Porsche 901/915: 911, 914 1969-1974
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.
For 7T pinion, 31T ring

Worth the money
This is a better way to buy the Busy Buddy replacements. You get 2 flavors in one package. With my picky pups, I never know which one they want so two flavors help with that!
