3/4 ton and 1ton crewcab frame difference?
- Thread starter stoney126

I believe 1 tons had bigger frames
There is a guy on pirate with a 3/4 ton crew with a 6 foot box. The way he did was cut off the spring hangers and move em forward. I was wondering If the dimensions or shape of the frame on the 1 tons would let me do the same

i believe there all the same but the 1ton has a 9 inch tall frame and the 10 and 20 have 6 inch tall frames.
someone correct me if im wrong.

SO a 1 ton frame would be kinda like a body lift?

When it comes to the crewcabs the 3/4 and 1 ton are the same frame. On the reg cabs there is a different frame.

So did mine. I was trying to say that all 3/4 crewcabs are really one tons but in the regular cab versions that is not the case. Crewcabs are 1 tons reguardless of what badge is on the fender.

That's what I was thinking.

As everybody else said, the frames on the crewcabs for 73-91 are identical for 20 or 30 series, likely due to the small number produced. They are the thicker/taller frame with the narrow spring spacing in the back.
The regular cab trucks were manufactured in enough quantity to make variations cost effective.
Note that my C20, a '74, came with the same stuff a light-GVWR 1-ton regular cab would have ... same spindles and brakes up front, same springs in the back, etc, but the extra weight of the body meant they had to back off on the GVWR.
I upgraded it to SRW C30 just by changing the springs in the back to the nine leaf plus overload monstrosities.
I then went nuts and did DRW, hydroboost, etc etc ... but that's another story.

Ah, is that what you're thinking about.
Note that some crewcabs started out life as cab-n-chassis', and they have a different frame in back ... prolly easier to put a shortbed on those, as IIRC the frame is flatter / straighter.

I thought there was the option for straight axle rails ... maybe that was the 88-91 NBS C/K C&C's. Aargh, my memory =))
