Rear coil-over conversion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am swapping to the trailing arm suspension on my 85 and was curious to see some pictures/details on swapping out the coil springs for some coil-overs. I know I don't own a 67-72 but I figured it would get more visibility/responses over here. I tried searching but didn't come up with much.

You'll want to significantly beef up the shock mounting points if you do this. I've seen more than a few shock mounts torn off the lower plate with stock shock absorbers and the coil springs still in place. If you ask that same lower shock mount to support the entire weight without the factory coil springs in place, you're most definitely going to be asking for issues.
