Stupid Question - '67 -'71 K10 vs. K20 Frame (Different??) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

arkracing · 09-28-2006, 01:50 PM

so is there any differance between a K10 and a K20 frame?

I know that the springs and axles are differant - but what about the actual frame - is it beffier @ all? - seems to me that they would be close to being the same???

or no?

anybody tow a car trailer with a K10??? - how does the 1/2 ton handle it?

If I remember correctly Longhorn said that the 1/2 and 3/4 are the same, it's the 1 ton frames that are beefier. Towing with a 1/2 depends on the load and how you are towing it. Weight is really the major factor because that effects everything. How it pulls, steers and most important, stops.

Cool - Anybody else know about this????
2cd opinions???

Here is a thread on my recent endevor - I have a few questions in this thread too - about Transfercase ID, Front Hub ID, and Tire sizes??

Thanks,
Andy

The Chevy restoration packet shows there is a difference in the 10, 20 and 30 frames. The section modulus varies between each. I find the following definition: The section modulus largely determines the flexural strength of a beam of given material.

That is kinda hard to decifer - but i'm guessing it either means that the section that goes under the cab area is "taller" or has a differant alloy of steel.

Seems odd that GM would make 2 different frames for the 10 & 20.

I'd be curious to see some dimensions on someone's original 20 series truck vs. a 10 series frame to compare.

(anybody already done this?)

They`re the same.

so if I put 3/4 ton springs and axles in my K-10 I have a K-20 (I know it won't be the real deal - but it is the the same as a factory K-20?)

This is dangerous - I already have all kinds of ideas for my new ride.

Yeah,the springs and axles/brakes.Both have Dana44 front axles with the difference being in the hub/brake area.
