Frame question 1/2 ton vs 3/4 ton
I have a 1/2 ton long bed 4x4 and I was wondering if it's worth it to you upgrade to a 3/4 ton frame I have 3/4 ton axles and springs. Going to be doing some towing. Any thoughts or advice thanks

Re: Frame question 1/2 ton vs 3/4 ton
I think the frames are the same on the 4x4 1/2 + 3/4 tons.
As far as towing it depends on where you draw the line. If its a ocasional 7000 pounds i don't see it worth the effort. If it is alot of towing, and closer to 9000 pounds then a 3/4 ton will be the ideal choice. |

Re: Frame question 1/2 ton vs 3/4 ton
The frames are the same.
What are the 3/4 ton differentials you have out of?

Re: Frame question 1/2 ton vs 3/4 ton
I've never had a K20 but the C10 and C20 frames are not the same. The C20 is stamped from heavier gauge steel and has extra bracing.

Re: Frame question 1/2 ton vs 3/4 ton
Could someone please verify that the frame for the 4x4's are actually 8 inches tall?

Re: Frame question 1/2 ton vs 3/4 ton
Confirmation: My 66 K 20 frame is somewhere between 8-8.25 measured from about the center under the cab. Didn't want to roll around in the snow to check further!

Re: Frame question 1/2 ton vs 3/4 ton
Thanks.
I wonder if they made the frame taller because a 4x4 may need to resist more twisting.
