70 swb question
My buddy has a 70 swb GMC with leaf springs in the rear. I thought all the early trucks had coil springs? All the brackets and mounts appear factory installed. It was originally a 6 cyl, but has a 350 now.
So did GM make leaf spring trucks in 70? Thanks!!

Re: 70 swb question
Most are coil but there are quite a few leaf spring trucks. I have a '70 Chev with rear leafs.

Re: 70 swb question
as I understood it, the half ton chevy's all got springs while the 3/4 tons got leafs. Is that not true?

Now 3/4 tons I'm not sure what was standard, optional or what not, but leafs feel right for the standard configuration with coils being optional. I don't even know if there is such a thing as 3/4 ton coil springs???

Re: 70 swb question
I have an original 1971 GMC with coils also. GM would build just about anything you wanted back then...

My 69 GMC is coil, and my 72 GMC parts truck is coil as well. Both half tons. My 70 GMC 3/4 ton parts truck is leaf.

Re: 70 swb question
ok... the 1/2 leafs were not an HD option, they were simply overload springs.
There was no HD option... just HD parts. 67 - 72 chevy, bit 10 and 20 series, came with coils, and leafs were optional. GMCs, in 69, coils were standard in 1/2 ton... I believe all other GMCs, 1500 and 2500's, 67 - 72 (other than the 69 C/1500) were leaf. |
