Is a c-20 frame and a c-10 frame the same? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Are they both the same? If not whats different? I searched but didn't find the answer.

Essentially the same, I believe I've read that the 3/4 ton frame has a little more bracing, but they can be swapped with no issues iirc.

Ok cool thanks, thats exactly what I wanted to here.

you'll need to use 3/4 ton cab mounts too, the mounts on the frame are mounted lower.

I wasn't swaping cabs or frames, a may be buying a c-20 but I want to do the disk brake 5 lug swap. Did c-20s have leafs or coils?

Longhorn Man · 08-28-2007, 10:21 PM

ok cool
C/20's could be had either way... the semi-rule of chevy = coils and GMC = leaf still apply... remember, if it's a longhorn, it'll have leafs regardless.

Ok cool cool ya its a chevy but I'll just have to look. Thanks again for the help guys.

The other thing to remember is that a 3/4 ton truck frame with coils will not interchange with one that had leaf springs, Or is it the rear ends that won't interchange?

Anything can interchange with a welder and grinder
