Soft(er) Ride Lift Coils?

currently have what i believe are procrap coil springs giving me 'roughly' 3" of lift. the kit came from a buddy's 95 V8 ZJ and the front coils seem too stiff for my liking; the front is very bumpy/stiff/harsh which makes for odd handling on the highway and a rough ride off road. the rear seems ok, most likely because there is the weight of a matching 31" spare, a storage box with my jack and CO2 tank, misc tools and fluids in the cargo area weighting the suspension down. im looking to replace the front coils with something that will give me a better ride on and off road and noticed that RE has a 3.5" spring with a 150 in/lb rating. how does this rate compare to a factory front coil? will this coil give me the more mellow ride im after or is it going to be too soft? i dont plan to put a winch or big plated bumper on the front either

thanks in advance!

I remember reading that OME(Old Man Emu) Coils were the best riding period for suspension lifts.

I have the 3.5 RE front coils and stock I6 coils in the rear with zone shocks. I'd like to think she rides pretty good. Off road and on, Anyways good luck haha

Yea, what whiteout asked. The shocks are gonna make the biggest difference. Get some nice shocks. I see you already have Bilstein shocks NM. Those are nice. I have the OME HD coils and I can say that they are very nice. They take bumps well and feel nice and firm in turns. Not too harsh at all. In fact I would like them to be a tad more stiff just for my personal preference. I am also running the 5100's.

5100s. they ride amazing especially compared to the 'white rocket' hydraulic shocks that the lift came with, those were HORRIBLE!

Next place you need to look is control arm bushings and shock bushings. With RE coils and Bilstein shocks, you should not have a rough ride, are the shocks an appropriate length for the lift? Bottoming out would cause harsh ride conditions.

the lower arms have poly bushings. i just replaced the upper arms (front and rear incl bushings) and the front axle upper bushings. the shocks are for 2.5-4" of lift and are nowhere near bottoming out.

im looking at the RE springs to replace the existing procomp springs in the front

Sorry, didn't realize you didn't have the RE springs lol. Guess I read the post of the guy below you.

Anyway, I has no issues with my RE springs with less than great shocks.

Rubber is so much better . Poly works good on sway bars . Top rated manufacturers use rubber bushings for a reason .

the lift was a freebee after a buddy went to long arms. id like to see about swapping over to rubber bushings as im not a fan of poly. heck, might even be a lil more flexy with rubber in em

Poly just doesn't retain it's shape after a shot period of use , especially on a lifted jeep . We flex and put a lot of strain on the bushings . Eventually , they oval and have play . Not to mention the harsh ride from them . I bet if you took out the frame side bolt , the arm would just drop to the floor on that end .

so apparently procrap decided to use some weird size for their bushings and i have had no luck finding rubber replacements. the only option was to get new poly bushings from procrap.....at nearly $100! eff that!

did some research/calling around and found that rough country uses OE style rubber bushings in their fixed lower arms. at less than $100 a pair, i went ahead and ordered em up for the front and rear. eventually i plan to go long arm with 4" springs, but for the time being this hopefully will help it out at least a little.

Rubicon Express used rubber at one end and a rebuildable poly at the other. Ran that combo for over ten years. They don't wear faster on built jeeps.
