Eaton 912A556 Detroit Truetrac 8.5" 28 Spline Differential with 10 Bolt for GM

This is amazing stuff. Thank you

As the tag line reads, no more dealing with differential posi clutches. Excellent fit and finish. The local shop who set my rear end up had no issues with this unit.Follow the instruction booklet and do not deviate from it. That includes NOT using synthetic differential fluid!!

I bought This Eaton posi unit for my 1982 swb c10. Great product from Eaton, rear end does its job. My only complaint is on how the really heavy rear end was packaged. It was just put in a cardboard box, no padding or anything. The box showed up looking like it had been used for a soccer game and there were about 3 holes in the box that I could see right in the box. I’m honestly surprised the unit didn’t arrive damaged but she’s all good. Just pack these things better!!

This diff is Bad Ass. I would recommend this to anyone driving this on the highway and off road. Love it.

Package was in good shape. Came a little early, which is good. Comes with a booklet on how to install, check everything, and test it. Can't wait to slide it in.

One part of a mechanical rebirth. Vendor pricing and shipping was good. Installation and first use will be delayed for some time.

I returned this product because it was apparently returned by someone else, you could tell because there was greasy fingerprints and writing for backlash on the torn up instruction book and the snap ring was bent and kinked, it also had the WRONG size bearings already pressed on ?
