68 gmc k25
I am looking to lift my 68 K25. What is the difference between the 67-68 and the 69-72? The best I can tell it's the rear spring length on the 68 is 57.5" and the later models have shorter springs. The front springs are 44" which seems to be common.

Re: 68 gmc k25
Naive question - what's a K25? Heavy 3/4 ton Chevy 4WD between the K20 and K30? Or a K2500 GMC?

Re: 68 gmc k25
i don't know of any suspension company making lifts for the 67-68 trucks. you'll probably have to have a spring company fabricate a new set of leaf springs in the amount of lift you are looking for.

Re: 68 gmc k25
What year did they swtich from K15,25,35 to K1500,2500,3500?
Or were the Ks always numbered differently from the Cs? Mine's a C2500, just trying to learn my models, and never had a K.

Re: 68 gmc k25
And if there never was a K15/K25/K35 this sounds like the most passive aggressive post in history, but I'm from where the GMCs are 910/920/930 so it's not a rhetorical question...
