Greetings all! Iv'e been back about 6 months now with an 87 k5 starting from scratch (pretty cool) is there any real isues with adding a 3" body lift on a 3" sup. lift? It won't be a crawler. with out the 3" more my 37" claws rub up front. any help would be great.
Well, once you understand that there is no single "lift", you're off to a good start. There are lots of different ways to lift your truck -- new springs, blocks, longer shackles, lifting the body, shackle flips, etc etc...
3" body lift is pretty extreme. Consider that you're putting your truck's body on 3" thick hockey pucks, held together by relatively small bolts ... if the mounts are all at rusted, it's a lot of leverage and somewhat risky. Imagine whacking a small Japanese car at just the right level and the body could justr slide right off
I'd look more at like a 1" body lift to get you a bit more clearance -- it does make getting at the gas tank easier, I gather.
Which gets me to my suggestion: a shackle flip in the back, which is easier to install if you can get at the tank

In front you'd have to replace the springs, or do the 52" thing, though that snowballs quickly.
And for that big a tire, you're gonna be best off trimming the fenders no matter what.
