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.

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

Still on brake in, did this in 373 with a yukon master rebuild kit, LSD, and a crush sleeve eliminator. Went together super easy.
