Running Gear Swap Questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey all!

Question 1:
I have an '87 1/2 ton 4x4 that came with a 7 spring pack on the left side and a 5 spring pack on the right side. 3 springs in each are cracked/broken and I would like to replace them with a good set off of a parts 3/4 ton 4x4 truck I have. Is this doable without swapping hangers?

Question 2:
I have an '88 parts Suburban that has 3/4 ton 4x4 running gear with 4:11 gears that I would like to swap everything, except the rear springs, under the '87 truck. Will I/should I swap the front sway bar with it? And will the front springs swap to the '87 without swapping the hangers as well?

Thanks for the help.

The fronts should swap out just fine. The rears mite be different lengths. Just measure from eye to eye on both sets to make sure. I don't think the sway bar would matter.
