3/4 Ton chassis - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Longhornss · 05-30-2015, 11:22 PM

Hey guys you are all a wealth of knowledge so I am going to ask here. I am in the market for a LWB chassis and have found a couple "locally" but what I need to know is, are all 3/4 ton chassis the same. Meaning I know they came either coil or leaf spring rear suspension but are the frame rails the same for both models? Does the coil 3/4 still use the smaller section width rails. I actually have a C10 and am looking for a frame to build up wile still enjoying the truck.

Thanks

The frames are the same. Brackets and bracings might be different.
By the way, welcome to the boards.

It's more complicated than that as a Longhorn is a 3/4 ton but has 1-ton rails and so. I think if you stick to LWB (not 133) it's more predictable.

So did the use 1/2 ton frames in the 3/4 ton trucks with coil springs. Is their any way of telling from a picture the difference between 1/2 and 3/4 ton rails. Other than measuring section and flange length?

I don't think there are any Longhorn 1/2 ton units. So far as I'm aware you could get 3/4 ton or 1-ton and there's not a lot of difference between the two. Don't know why they're not just all 1-ton, they already have the rails, and I think only the front suspension and maybe leafs differ.

Someone posted the specs on these frames a few years ago. 1/2, 3/4, & 1 ton frames look the same but the rail thickness is different. Progressively thicker, stronger. I lost those frame specs to a crash.

Thanks for that I did see these specs on the site someware and was curious to ton if maybe some of the leaf/coil configurations used different frames.

Ez way to tell 3/4 from 1/2 from pic is the 1/2 t rear body mounts match frame height, 3/4's are lower..

Cool thanks for the information that helps out a lot. So when Leo called you which frame was he calling about?

He was looking for a 1/2 or 3/4 lwb.

I have a 68 and 70 3/4 lwb and just sold the 72 1/2 LWB.
Should be getting another 72 LWB this coming weekend......

What I am looking for and what he should be looking for is a LWB 1/2. Where are you located? He has talked to me about a few different chassis he has found.
