There are a bunch of reasons I'm *thinking* of doing it.
1-no 3/4 ton Yukons/Tahoes.
2-can't swap frames. Refer to #1. Thought bout a burb frame, shortening it, but that's a rather large task. I don't even have a garage.
3-want 4.10s. I can get 3/4 ton GMT-400 and 800 parts cheap. There is a metric **** ton of them in one yard, I have access to prolly 5-6 with almost as many. Yeah I can buy 4.10s for the stock 8.25, but would have to pay someone to install them, prolly $500 all together.
4. I want 8 lug. I have a set H2s that look pretty good on the Yukon. 8 lug wheels are all over. I have a 14 full float axle with 4.10s just about ready to go in the Yukon. Not that I'm gonna go crazy, but don't have to worry bout breaking a 14 bolt. Govlock or not, they are tough.
5- bigger brakes. its what got me here, reading the post on the GMT-800 brake upgrade, someone said it would work with 8 lug too. So, here I am.
Like I said, I'm thinking of doing this. I have 90% of the parts to SAS it. DIY4X SAS kit and crossover steering kit, 2 sets of springs, 4" 48s and stock 52s, complete outer rebuild for the HP44, carrier rebuilt kit, new 4.56s if I decide to run those, a Powerlock, DIY4X shackle flip, sure there is more but get the point. Bout only thing I need is calipers/pads/brakelines, and u-joints for the front axle. The H2s already have 35s on them, so would be good for the overall lift.
Yukon is in pretty good shape for being a 96 and in the north east. Don't see too many like it, lifted or not. Having a whipple is a bonus. Having it SAS'd would be even better. Right now just want to get it going and on the road. Get the feeling gonna need brakes all around, and with my luck new calipers. So if I need to do brakes, why not do em once, with 8 lug stuff. Least how I see it.
I might go to the yard and grab an upper off off a 3/4 ton as see if it will go on or not. Think that will answer a lot of questions!!
