Great product

I am amazed. I can put one tire in wet grass and the other on the road, and it locks perfectly. It makes no noise at all, goes around corners perfectly, and always spins both tires. With a regular posi, I ran 1.7-1.8 60 ft with drag radials. With this and an anti-roll bar, the M&H drag radials are now 1.5 60 foot times in a 3300 pound car. My 10 inch slicks 60 foot around 1.3 to 1.4 seconds. 5500 RPM, 10 psi boost, and pop the clutch. I'm going to put one in my truck. I'll never use any else for a posi. Well worth the money. ...read more

Big difference over stock

Summit RacingSummit Racing Verified Purchase

I used to get decent wheel spin in second gear. Now it hooks and cooks. This is the first aftermarket diff I ever put in my cars. Will be using it again on future projects.
