Ride Height

[Berndtc426]

I have a 72 GMC 3/4 ton 4x4 that lifted. I'm not sure how much it's lifted but I like the ride height. I want to get a different frame and lift it by making my own spring mount brackets. Leaving the stock, (or near stock) springs. So my question is if I start with just the frame how much lower will the frame sit when the drivetrain and body are on? Does anyone have a mesurement of frame height with the drivetrain and body on, and then bare rolling frame? Any info would be great.

Just measure your frame now and when you get the new frame set it on jackstands at the same height. Get the axles under it with the stock springs and build the brackets to the height you need.

Thats exactly what I plan on doing, except I don't know how much lower the frame will sit when I add the weight of the engine, trans, transfer case, cab, bed, fenders on. I don't want to set it at exactly the same height, because I know it will sit lower with all the weight on it, but I dont want to set it up too high either.

two inches would be my guess just based on spring rates and the weight of the drivetrain, frame, and body.

Why are you swapping frames?

I want to swap frames because I want to build my own suspension...kinda. I still want to use the stock springs, but do some other fab work. I can't do it to the frame thats under the truck right now because it's a daily driver. The person who owned it before me did some welding and other stuff that doesn't sit well with me, so I would like to fix that as well.

You might get better luck of finding measurements in the 67-72 Truck section.

I think I'll try that, Thanks for you help.
