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.

Parts arrived early and look to be high quality, install was easy and no noisy gears now, run quite like they should ! Great value for the money.

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

Lasted about 8,000 miles hairline cracks on pinion teeth
I recently have had some crazy noises coming from rear area i changed absolutely everything trying to fig it out like my front differential.rear differential. drive shaft . Rear axles. Transfer case. Carrier bearings.and now went to change pinion bearings when i found hairline cracks all over the pinion teeth.that might explain the noise getting worse as it warms up after driving a bit so now i wait for a new one. diff brand of course.and only drove for maby 8,000 miles in the year i owned it

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
