Eaton Posi differential carrier 19557-010

Summit RacingSummit Racing Verified Purchase

This is a great product! I installed this in my 1974 T/A 8.5" safety track. Had to use different side bearings to install as noted in the Eaton instructions. This differential carrier is almost identical to the stock differential carrier made for GM by Eaton in 1974 with the exception of the different side bearings (use .242" side bearing shims for pre-load and tooth pattern) required. Great, great product. ...read more

great differential

I've installed well over a hundred of these. The Eaton Posi is one of the best limited slip differentials that you can buy for street and moderate drag racing. And if you ever wear it out it is completely rebuildable.
