3/4 ton cab v.s 1/2 ton cab?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**chev-obsession** · 06-15-2009, 09:23 PM

is there a difference between a 3/4 ton cab and a 1/2 ton cab, like the way they mount to the frame?

Tx Firefighter · 06-15-2009, 09:30 PM

No differences in the cab itself. The frame mounts and rubber cab mounts are different though.

Longhorn Man · 06-15-2009, 09:52 PM

only thing is the 2 on the VIN instead of a 1.

A little off thread but:

My son and I found out the hard way that the cab mounts are different on a 3/4 ton than on a 1/2ton.

We took a cab off a 3/4 ton and put it on a 1/2 ton frame using the 3/4 ton cab mount stuff.

When we tried to align the front clip we found the gap at the fender to the cab would not work.

One day when I was searching this forum I found out why. The frame brackets on 3/4 ton and 4X4s are lower on the frame allowing for thicker rubber mounts to allow for a smoother cab ride.

this makes me wonder. I bought a cab and was "told" it was from a 1/2 ton. How do I really know?

Longhorn Man · 06-15-2009, 11:32 PM

the vin?

Andy, such a short answer,
Help another one out. You know he's new

I would have figured that out from your previous post. It has no vin plate in it.

If you have no VIN plate or any numbers to go on, then there is no way to tell and it really won't matter. The actual mounts on a 3/4 ton are different. The cabs are totally identical, the mounting locations are the same.

thats what I wanted to know. Thank you.

i figured I'd be a smart ass, since keven already answered the exact same question, on this thread, in the first responce.
i'm just sayin.

**leddzepp** · 06-16-2009, 09:52 PM

Good question, and good answers. I was wondering if I could just buy a set of cab mounts for a 1/2 ton for my 3/4 ton truck....since the 3/4 ton mounts cost twice as much. Now I know that I cannot do that and will have to buy the 3/4 ton ones

**chev-obsession** · 06-17-2009, 02:38 AM

so baisically if you have a 3/4 ton cab, then you use the 3/4 cab mounts if you were to put it on a 1/2 ton frame?

**El Jay** · 06-17-2009, 02:41 AM

I think you may have it backward.
Use the mounts that go with the frame.

You are overcomplicating this. El Jay has it right, you just use the mounts that are on the frame. The cab doesn't care if the chassis is 1/2 or 3/4 ton, it will sit there, bolt up, and look pretty either way. In a nutshell, don't mess with the mounts, just slap the cab on.

Well I wouldn't say don't mess with the mounts. If you have the cab swinging in the air by a strap, that is the perfect time to mess with the mounts. Throw away the 40 year old factory ones and replace them with a new set from a supplier. Then you don't have to worry about the cab and bed body lines not lining up for another 20-40 years.

Figment412 · 06-17-2009, 03:25 PM

Neither the 3/4 or 1/2 would work on my truck so we had to come up with a custom setup. We ended up with a 2" body lift.

69GMCLonghorn · 06-17-2009, 03:31 PM

Slight tangent on the same thread:

My cab mounts are there, but severely cracked and dried out. I'll also add that I have a very BOUNCY 1-Ton. Will I actually notice a ride difference if I replace the mounts? Or will it just be money down the tubes?

When I refer to mounts, I am referring to the metal brackets riveted to the frame. The rubber portion is definitely something to be replaced.

Yes, you will notice a ride difference. Replacing those dried out cushions with some new ones will provide a lot more give than the current ones do.
