Default 1999 Suburban - Let's talk Solid axle swap

I'm sure this has been discussed before - but I have a few unique questions.

It's time to do the Solid swap into the front of my 99 Suburban. I will be using a 79 ford dana 60. I've done other solid swaps in the past (Chevy S-10) but I've always fabbed up everything myself.

I want to keep it as close to stock height as possible. I've been looking at the various kits out there, and they all net 6 inches of lift in the lowest form. I've talked to the companies, and they all say 6 inches is needed to clear the steering.

Well, I've looked at their six inch install pics, and in my opinion, there is plenty of room for the steering if it was lower. I also hate the fact that most of them make really low front hangers that almost look like plow mounts.

I'll be running a cummins so this will need to be stout. I'm considering using 3 inch wide ford F-350 front leafs instead of the 2 1/2 wide chevy rear leafs that the kits are designed for.

Fabbing is no issue for me. I'm looking to hear from others who have done 88-99 swaps before, and how low were you able to get away with.

how about using stock 3500hd front springs and mounts, all the mounts bolt on the frame and the springs shouldent make the truck sit to high. just a thought

food for thought

you are doing so many mods why dont you just use a solid axle burban frame. use your body on it. you will not need most of the factory wiring harness anyway. it will give you a clean slate to do the motor and trans swap.

Im pretty sure I saw a suburban with a 4 inch lift and a sas. It was about the lowest he could go. Ill try to see if I can find it on the internet and post it up for you.

The spring perch width on those things is something like 38 inches, and I don't believe any of the parts will bolt up. Plus they sit spring under, and with those springs and a spring over axle, you'd end up with a good 12 inches of lift.

It's a thought, however the 73-91 suburban frames require work as well to get the cummins to fit. Plus my bumpers/body mounts/fuel tank work with my frame. And my frame is rust free.

Lastly, the 2500 HD suburban frame is almost twice as thick and much more well built than the older suburban frame (I have one of those as well for comparison). The only drawback is the IFS

well if you consider that the Cummings you want to drop in weighs about 1300lbs then you may have to bulk up your front end a bit? the big block that is there is a light 690lbs by comparison

Find a pre 1991 3/4 ton suburban with 2 leaf front springs and use those, they don't have any arch they are flat. If the two leafs still are not enough to support the diesel weight add a leaf.

PM Raymo on here. He's a friend of mine who turned a 93 2wd gasser Chevy into a 4x4 cummins. Did an awesome job on it too, then he decided to tear it down and stretch the frame. Here's a link to his build: www.greatlakes4x4.com/showthread.php?t=159298

Thanks, I did PM him. He's basically doing the same thing I am with exception to the lift he is running. It's nice to see how others work out the problems I will be as well.
