C vs. K
Okay, I am a newbie, but I was pretty sure that the C series of truck C10, C20, C30 was 2wd, and the K10, and K20 was 4x4. I am constantly seeing trucks being sold that are listed as C10's and C20's, but that are also running 4x4 drivetrain. Am I missing something special about the K series....should I assume that a truck listed as a C series that is 4wd is either being listed by someone who doesn't truely know what their truck is....or its a 2wd on a 4x4 frame? Or were C series trucks sold with 4wd from 67-72????
Thanks |

A factory "C" series truck should be 2wd, however, there are Custom/10 and Custom/20 as well as CST/10 and CST/20 trucks that can be either. Blazers are a different story - all Blazers are K/5 whether 2 or 4wd.

I believe the difference is the model number on the glove box door v. badging.

Also, they never made any K badges, except for the K/5 Blazers. So a 4x4 3/4 ton truck will have C/20, Custom/20, or CST/20 emblems, and a 2wd 3/4 ton truck can have the same.

After 33-38 years of surving, by now alot of these trucks could be pieced togther.
I have seen many "4WD's" with a 2WD VIN number. Even though it's 4WD it could have been a 4WD from day one where someone later does a cab swap from a 2WD. In which case the actual title VIN would be correct yet. So when you see a 4WD with a "C" Model number and not a "K", heads up! something funky is going on. And vice-versa, you could have a 2WD with a 4WD cab put on it.

... quick follow up, from the factory you won't get a 4WD truck with a "C" series designation in the VIN or Model; It will be "K' if 4WD.

Bottom line is that the fender badges don't mean anything when it comes to 4 vs. 2wd. The C or K in the first position of the VIN (or the second position on a '72) DOES indicate 2 or 4wd.

My truck has the stock C-20 emblems on the fenders, but I call it a K-20 because thats what my VIN starts with, KE2xxxxxxxxxx I not sure when GM started using the K for the truck, sometime in the late 70's I think.
When in doubt..... check it out! GMC Pauls VIN decoder page. http://www.gmcpauls.com/chevrolet_data.htm http://www.gmcpauls.com/67-72_chevy.htm |
