A pic would help a lot, and what size tires are on it now. Most of us could guess within an inch or 2 how much higher than stock it is or what size tires you could run.

thats what it looks like to me..when it was done a place here made all the springs and the owner told them he wanted hvy duty and big enough for 35"..now i have 33x12.50x16.5..yes 16.5..i bought a set of brand new GMC 16.5x9.0 wheels..so i found a place on line that X military tires like 36x12.50x16.5 and can get a very good price.But dont want to order them and have to cut the body..thats not happening will carve up this almost rust free Burabn

If those are 33" tires then that is deff a 4" lift. I have 6" and fit 35s or 37s.

Do not run military tires if you plan on going on the highway and DD this thing. Been there done that bad idea. There is a reason they are so cheap, because they suck!

Im running the 36 military love em. 60 miles a day no highway but thats do to 3spd and 410s not tje tires. 55-60 they roll like a dream alpha tread is where i got mine. 90% life they should fit they mesure a lil small.

I actually bought this truck down by you breeze il. Now this is 4 inch susp and 3 inch body

OK ...so im thinking it ended up being about a 4" lift..now it has no blocks it is all spring.I really want to run 35's for a little less hiway RPM..but 87Scotty i found that place you speak of and one more with good reviews. The tires are 36 E rated radial tires like 85/90% tread AND they are 16.5 which everyone tells me i should dump..But i wanted a TRUE 1 ton and back in the day 1 tons ran 16.5s so i bought a set of GM white steelies..I just dont think its tall enough for the 36's...

Anybody running 35's on a 4" ish lift..the nice thing about this was the use of GMC leaf spring mounts all the way around,no short cuts with a wunky shackle only mount..this thing drives so straight down the hi way..so i do not want to FUBAR that trying to cram a tire under it that doesnt fit..

Those factory wide 16.5's are awesome! I'd also want to run the military 36's, they wear well and have a good classic look to them.

Hay Bob. Wtg, looks cool. Easy 4 inch if it's not 6. No? How do the driveshafts look? 4 is a common SUSPENSION LIFT.
