Excellent
Fit as it should. Works perfectly. Doesn't come with outer axle seals or bearing

If you want good performance parts you buy Yukon gear
Extremely high quality made in the usa parts. I've bough soooo many Yukon gear parts over the years and had very minimal part failure ( and only failures where in very high horsepower race application rigs that where taking far more abuse than your normal daily driver or weekend warrior rig would under go) there fully worth the money.

Dead silent rear end
Ordered this along with Yukon gear posi since my G80 shat the bed. DO NOT order the 'bundle' as it jacks the price up over the price of purchasing individually. Everything we needed to completely rebuild the rear end was included with the exception of axle seals, bearings and oil. Rear is now dead quiet.

Thorough cleaning before install is mandatory
These installed in my 2000 Silverado with new Yukon gears. Everything was textbook.

All the bearings did not fit the vehicle!
Overall the bearing kit was very good! Had my mechanic install the kit, but in the process he noted that two of the bearings did not fit my 2004 suburban z71. He sourced those two locally and completed the job. Would buy this kit again if need be.

Parts appear to be high quality.
I can't give this a less than great rating as my product was damaged in transit. Yukon makes great parts! Everything appears to be usable minus a seal. The blister pack broke open and bearing and races were able to bounce around and ding up all the other parts. All I can do is clean up the burrs and damage and run it as I dont have time to replace it. Will update.
