dont know much about the 67-72 chevy trucks, as i assumed that all 2wd's used trailing arm suspension. But today i looked at my 69 c10, its got leaf over...

IIRC, 1/2 T Chevys came standard with coils and leaf springs as an option.
GMC was just the opposite.

If I'm wrong, somebody will chime in & I'll put a paper sack over my head & say, "Oh, Father, I'm so ashamed."

Believe you are correct El Jay. That's what I remember too.

in 69, GMC had coils standard on the 1/2 ton trucks.

Wow, I didn't know that. Just for one year? Sounds like something GM would do.

You can convert your truck to coils fairly easily

Longhorn Man · 03-20-2009, 04:17 PM

actually, I think there may have been another year too, but I know 69 did.

Hoffman65burb · 03-20-2009, 04:19 PM

oh cool thanks for the info, any advantages/disadvantages to this setup?

The coil spring set up is a very good layout. Look under the 200-ish MPH NASCAR cars and you'll see the same thing.
These give a better ride, they 'hook up' better when you lay on the horse power, they handle just as much weight as leafs...
They do make exhaust work more involved, and there's more work to do when you lower them more than a few inches.

I have lowered a ton of leaf trucks (this is my first trailing arm truck) and this sure seems much easier. Granted I haven't done my C notch yet but I have had a really easy time with it so far.
