Is there any real difference between 6zg/7zg, 6zf/7zf, and 6zh/7zh? I have an 05 colorado z71 reg cab ls 4x4. The codes in my glove compartment call for 6zg/7zg.

I believe they are coded by cab and motor configuration. But, I don't know for sure. Are you trying to find replacements?

Yea. I have one set of spares. Looking for another as well. I'm wondering if they are the same size regardless of cab and motor configuration and drive train.

The length is the same. I think the difference is how much torsional force (weight) one will carry.

And they all hexagonal? Same size to fint in the control arms and keys?

They are all essentially the same except the V8 models are more “HD”.

I’ve got a set of V8 TBs I’d part with pretty cheap if you’re interested. 😉 I imagine shipping would be costly though.
