Gr. Cherokee coils?

A few weeks ago i scored a set of springs that were in the back of a grand cherokee. remembering that they give roughly an inch more lift, i bought them. i'm pretty sure that they are v8 ones but i'm not positive. they are about .050-.070" bigger in wire diameter than my stock ones. is this true about the v8 coils? thanks for your help.

Inthe back, as in rear suspension, or front ones sitting on the back seat??

rear springs will do you no good, you need the front springs.....

the front ones in the back seat

they're a stiffer spring rate, and generally net a few inches of lift.

i have my own stash of parts in the back seat.... right now there's a pair of shocks for the rear. i can't get the old ones out so i'm PB blasting every day. i'll give it a shockin a couple days again. really don't feel like cutting stuff. sorry for the aside.

I tried the V8 Front G.Cherokee springs and i got about 1.5" lift and i added another rubber insulator that sits on top of the spring in the perch and got me to 2" lift.

That was a couple months ago, since i have upgraded much of my suspension. But it worked with 30's well at the time.
