Quality parts for a very fair price
Using the complete bearing kit that I ordered along with the gears, the install was pretty straight forward. After about 4 mock ups, the gears went in fine. Even though I put a few hundred miles on the clock before towing, the temps got pretty high. I would say that before towing you should put over 500 miles on the odometer before towing. All is good now though. Temps 160 with 100 plus temps outside.

Solid! Held thru many burnouts on 24s for about a year lol. If you don't abuse like I did they'll last for years

Good fit
Came in on time and fit perfectly. Over time Once it “broke in” it’s starts to make a howling noise when accelerating and decelerating.

This was correct description
I can’t say because I never installed this part but it was the correct description I just ordered the wrong part but it was a good lookin material and would work if I needed the 3.73 gear ration

GENUINE PRODUCT
This is a genuine Yukon product. Or at least the one I received. It's all brand new and on a Yukon box with an insulation manual. I will give updates later on if it preforms well . 3.73 ratio 10 bolt Chevrolet
