(YK GM12T) 12-Bolt Master Overhaul Kit for GM Truck

Very good quality. Just what I needed to get the tope end remote i wanted

this went alot smoother than i expected in my 2k grand marquis ls with a 8.8 diff. i wish they would label the bearings on the cards just to make it easier when you go to get them so you dont have to triple check yourself to be sure you have the right set. of course that could just be me, i just triple check it so i know i dont have to pull it apart again.... the shim kit was plenty for me, and i dont know if it was dumb luck or excellent oem fitment but i was able to reuse my old shims and my pattern came out perfect first go, i do wish they would offer this kit with the axle bearings and seals along with it so you can just do it all at once with one kit. but this went so much smoother than i expected, i had a bad axle bearing that ate into my axle, that caused a bad carried bearing so i just redid it all in my driveway, car rides smooth again, no noise at all. even after 16 heart attacks i was able to do this slowly and it only took me about 5 hours with hand tools thats even pressing them on with a old bearing and a small sledge.

Exactly as described. Fit perfect.

Aun no probé este kit en concreto,pero ya use hace años uno igual y funcionó perfecto.

Everything went in my 60's ford 8" without issue, but as others noted the pilot bearing retainer is not included for some reason - has to be ordered separately. Yukon part number YSPRET-001. You could flatten out and reuse the original one, unless the last guy did the same. Crush sleeve not shown in the pictures, but was included.

There is no description specific to this particular kit. I had to buy it hoping that it was the correct kit. There are multiple versions of the dana 30 front axle. One being a reverse rotation or high pinion d30. Another being a low pinion also referred to as short pinion. I have the low/short pinion axle. I bought this kit to install my new gears and while most of the kit is the same as the high pinion the outter pinion bearing and race are different. This axle also requires a crush sleeve which this particular kit does not come with. All other components are compatible with what i need. I have already installed the seals carrier bearings and inner pinion race. It wasnt until i was installing the outter pinion race that i noticed that one bearing is different in this kit and that there also isnt a crush sleeve. I have to run to the store and buy the outter bearing and race along with a crush sleeve separately now as im not removing these parts and waiting on shipping to do a return. This isnt quick performance’s problem. This is a yukon problem. They talk about the hundreds of kits they offer but offer absolutely no information on the kit your trying to buy…. I just wanted to let you know of this issue so that maybe there will be updates in the future so we know what we are buying from you before we click purchase. Great product as always! Just poor description which unfortunately is also typical.

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.

I ordered this kit on Monday when i realized the kit i got from the auto parts store had the wrong carrier bearings in it, and i had rung off one of my ring gear bolts, and stressed another beyond reuse. I know , I know, all the videos did say they were left hand threaded, but old habits die hard. Anyway with prime shipping, I had it in my hand by noon on Wednesday, and I got it put back together and test driven that same evening. My first ring n pinion set up, together with youtube, and detailed instructions in the kit I am proclaiming success. I didnt realize that the carrier bearings for my trutrack were bigger than stock, $170.00 down the drain for that kit. Incidentally this youkon kit cost about the same, and came with replacement ring gear bolts, two crush rings, and pinion & carrier bearing shim kits, and an acid brush, Timkin bearings and races and detailed instructions. None of wich were in the auto parts store kit.

Muy buena marca

YK GM8.5-HD install kit for GM 8.5 carriers with the oversize bearings: Everything you need to assemble your new diff with Timken bearings, new bolts,etc. 7 pinion shims allows a wide variety of adjustments, 2 super carrier shims make install and adjustments easy. Locktite for bolts; pattern compound; pinion seal; 2 crush sleeves and gasket round it out. Overall great kit.

Everything I needed

Great kit.... But I ordered the wrong one. I identified the diff by the diff cover which looked like a Dana 30 but the internal components turned out to be Mitsubishi Pajero .. Never assume.

Came with two of the wrong bearings I got two kits and both were the same
