Did a 70 Chev CST C10 2WD ever have a rear leaf spring option, or heavy duty half ton?

Yes, I think you could get the leaf springs as an option. It should be listed on the SPID sheet on the inside of the glove box door.

Going to pick the truck up Monday in Montana seller said it had leaf springs and I had never heard of that option. Thought it was only GMC.

My brothers 72 short bed cheyenne 2wd has leaf springs. They're listed on the spid,but I was a little surprised the 1st time we looked at the truck.

**too much stuff** · 03-13-2021, 08:45 PM

Could have leafs or coils, and could have the camper option even.

**James Pierce** · 03-13-2021, 08:50 PM

Well was a surprise to me and I got a little nervous since I had made a down based on pictures. Leaf springs on a Chevy should be good bench racing trivia.

My 71 has rear leaf springs. Option code G70. This code is listed (online) for multiple years.

PepperTreeGarage · 03-13-2021, 08:57 PM

On our '72 C20 it is listed as a G70 option.

**James Pierce** · 03-13-2021, 09:02 PM

Have a 69 CST Camper Special with wide tires in rear and it has coils?

**Steeveedee** · 03-13-2021, 11:11 PM

What does the SPID say about wheels? I worked for Chevrolet dealer(s) on and off over about 3 years, and have seen big (10.5" wide) wheels and tires even put on demonstrator trucks which would not be on the SPID.

You could convert to coils if you like
Yes both coil and leaf sprung trucks had a hd spring package
My 68 had the hd coil package and my parts 70 k10 has hd springs

My '68 CST/Custom Camper has coils and 16.5 x 8.25 wide wheels. It only lists the spare wheel on the SPID.

My dog gone 71 C-10 SWB 2wd has leaf springs, the guy wanted a Chevy emblem on GMC suspension I guess. It's not a blessing when you're looking for parts.

OT: Something that finally dawned on me the other day, Z62 on the SPID is another way of saying it's the "Deluxe" trim level. At least in 71-72 terms.

I have a 1968 C20 Custom Camper that also as the optional heavy duty rear leaf springs. Option G70

Dross9065 · 03-14-2021, 10:08 AM

I believe all Chevrolets were standard with coil springs and GMC were standard with
Leaf springs, but both could be ordered with either spring option.
