what lift for 40s

I've been wanting to upgrade from my 35 BFGs for a while. I'm looking at a set of 40/17/15 ground hawgs. How much lift will I need to run to handle these tires? Currently i've got a 4 incher suspension and a 3 inch body lift. I wouldn't mind upgrading to a 6 inch suspension lift but those 8 inchers seem to have a lot more problems and $$$. I don't want to cut the fenders anymore than they allready are!

Here's a pic of my current setup. [not flexy]



Also I've got a nice built 350 w/ a th400 transmission and the 14FF rear but I know I'll be needing to upgrade from my 4.10 gears probably to 5.13.

i am not an expert but i bet a 6" lift and 3" body lift wont clear 40" tires without some more trimming, if you want to have flex without the tires rubbing. i have about a 6" lift with massive fender trimming and no real bed with 39.5 and they rub when i drive over little rocks and whatnot.

Ah trim the fenders ya puss
That thing has a 3" body lift?? I would think a 6" lift and a 3" body lift should clear with maybee the slightest amount trimming. I have a 6" lift and 38.5's with some trimming. There are pics somewhere of my Blazer.

thats odd, i got 5 inch lift with 39.5"s with a lot of trimming, only place i rub is in the rear wheel wells, but ill fix that by tubbing the rear wells.

that thing is pretty ugly already, a little big of trimming won't hurt

You don't need more lift. You need more cutting.

Is this a daily driver? If so, you don't need huge tires. If not, then why don't you want to trim?

my sawzall is the bestest lift. not only was it relatively cheap, but you can put it on several vehicles as long as you buy plenty of blades.

ive got the 39.5x18 boggers and the edge rubs on the front on the frame and a couple of places when the steering is all the way over and flexed.

just trim the fenders. I run 4" springs with 39.5 TSLs np. IMO, my fenders look better than stock... of course... thats just MY opinion.

I agree im running 39.5s on my blazer with a 2 inch body and 6 inch spring with a healthy amount of fender trimming. IMHO that just means less sheet metal to get dented.

I am from Raleigh too. Do you live with Chris Hankins? I have seen that truck there before.

First concern is I think that is a 3/4 ton, right. 40's are a little big on 3/4 ton fronts, you might want to consider a dana 60 swap. Unless you only drive it on the road, then you probably will be fine with the 3/4 ton fron.

I have heard that 40" groundhawgs are not really 40's, but they are smaller. With 6" springs and possibly a zero rate in the front, and a shackle flip and blocks in the rear. you can definetly fit the 40's, if you only drive onroad. IF you do alot off-road and you really get twisted up, then your tires will rub.

I used to run 40's with a 6" and a 2" body, and about the same amount of trimming you already have. It rubbed a little but oh well. How about going to a 6" spring, sliding the axle forward 1.5" and running your sway bar still. That should work pretty good.
