GMC Experts?????
Here is a '72 GMC with some nice options. I thought GMC's were all leaf spring rear suspension. Any ideas other than a GMC cab/bed put onto a Chevy frame?

Re: GMC Experts?????
Coil springs were optional, I assume that's what your G50 code is.
I believe Chevrolet was the opposite, coils were standard and leafs were optional.

Re: GMC Experts?????
Would that mean that all HD rear springs for 1/2 ton 2wd trucks were coil springs?

Re: GMC Experts?????

Re: GMC Experts?????
Coils were still standard on GMC, if not the leaf option would not be listed on the spid (like below). For some reason most but not all GMC's (in 1972 anyway) had the optional leaf springs.
All the GMC's that I have owned and had leafs also had leafs listed on the spid, which tells me that it was still on option and not standard. Maybe I am wrong......

Re: GMC Experts?????
Thanks for the feedback! The listing of leaf springs on the SPID makes sense. I wonder why most light duty GMC's were leaf spring while most Chevy's were coil spring? It appears that at least all '72 1/2 ton trucks would have coil springs unless noted on the SPID. Therefore the SPID shown at the top looks to be correct for a GMC with coil springs.
Thanks! |

Re: GMC Experts?????
just tell them what they want to hear. If the parts are the same as a chevy big block, then just tell them that.
I don't bother telling the parts guy that I have a cad motor in a c/30, I just get parts for a caddy. |

Re: GMC Experts?????
Try convincing someone that your Chevy came with leaf springs in the rear. They will act like they still do not believe you even after seeing the SPID.
