GMC Longbed shorten w/leafs?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BP68 · 11-22-2007, 08:09 PM

Hey all,

I have a 70 GMC longbed truck with a Chevy front clip on it. I will prob sell it, but was wondering if anyone has shortened a longbed frame that has rear leafs rather than springs/trailing arms? Just wondered how much diff the process would be.

early classic shortens the frame under the cab with that you only change the rear cab mount...which i did to my 67 but i have coils but doesnt change to process earlyclassic.com tech articles

The frames are the same,just the spring hangers and springs are there and not trailing arms..The chunk taken out to make a shortbed isn't between the leafs so no issues there.Basically the same as shortening one w/ trailing arms,just don't mess around with relocating the crossmember for the trailing arms forward.

I have a gmc frame too that i have shortened, the only problem is the bumper bracket bolts where the leafspring is but im going to run a rollpan.

Look up "lfd's low buck truck build" and you will find everything you need in a step by step thread.
