Just out of curiosity, does anyone know what the difference in Height was between a '77 High Sierra model, and Standard Sierras/Chevy's of the time??? Been thinking about doing a 2.5"-3" Lift over my trucks current height, but since I have heard a few people say that a 2.5" lift is basically Stock Springs + an Add A Leaf(Which it almost looks like my truck already has), I want to make sure that I wouldn't be just replacing what I already have, or making it lower!
Aside from the Tires(I think an Inch or two over stock), my truck seems like it is already taller than other "Stock" 4wd Chevy's/GMC's....

High Sierra has nothing to do with the suspension, it is a trim level - RPO Z62. It is 1 level up from standard and 2 levels below top of the line for 75-81's ( 1 level below top of the line on 82-87(91).

Thanks for the reply Capt, guessing the previous owner did put a lift on it at some point, but just never mentioned it to my Father-In-Law(From what I was told, it was an all Original Truck, but things don't add up here and there!)....

Being a 1977 K series I wouldn't doubt it. What size tires are on it?
-
I'll get back to you later on the size Capt, I got to be heading to work shortly, so I will check it out when I get home....

BFG M/T 255-85-R16 is what it currently has, don't know how that converts to the Early Size Ratings that were in use when the truck was new....
-
those are roughly 32" tall. The biggest ever from the factory were 31's.
-
I was coming up with around 33.067/33.1 average for what I currently have, and guessing roughly 30/32 for the Factory Size... My truck still seems like it is an 1/2 to 1" or more, on top of the tire size difference from stock, atleast in comparison t other "Stock Height" trucks I have seen...
