Check out OME coils they have two different spring rates the light duty for Cherokees without a winch or heavy bumper and a heavy duty rate if you do have a bumper and winch. ( shocks will affect the ride a lot )

ok bilsteins are overpriced for the mostly same quality of jackers. and plus bills cost 3 times more then jackers. sold auto parts for 5 years. nitro jackers work very well. I have the drop brackets with adjustable iron man fabication shot arms. the cheapest thing on my truck was the coils. they where pretty much free. so please dont tell me things i have a junk because there not. this was a easy question about coils not the other gear on my rig. it build right. just looking for the best coils
The reason everyone is telling you to look into other things is because there are A LOT of things that come into play...not just the coil...we are answering your "EASY" question about coils...
And as already stated, this isn't a Cadillac.
