Post subject:  OME spring selection

I have a 2005 KJ 4x4 that has been my wife's daily driver since new.
At about 30k miles we did a 1/4" clevis lift and added a couple spring isolators in the rear. We have been running BFG 245/70-16 since then.
A year or so ago we added an ARB front bumper and its weight has taken it's toll in the front suspension and it's time to upgrade.
I have decided to use Bilstein struts due to my experience with them on other vehicles. I have only found good reviews of OME springs and plan to use them to replace my tired stock springs.
I have searched the site and read the tacked threads and still I'm not sure what spring to choose. My first thought was to choose OME 790 springs but I drive 2 diesel trucks and "bigger must be better" is often my first thought when it comes to weight capacity. My concern is raising the front too high. I'm not looking for a lift really. We were happy with the clevis lift and stock bumper. The OME springs are advertised as providing 1 1/2" lift add that would be great but I also see lift kits using these springs and claiming 3 1/2". That would be a problem. There is only the slightest chance a winch would be added to the bumper. I don't plan on swapping rear springs, only replacing the original shocks. I don't want the KJ nose high. What springs should I use? How much lift will there be? Thanks for reading and any help you may offer, MBanning

OME 927s will lift the KJ 2.5 inches ( other posts you have read also include clevis lift and top plate to reach 3.5 inches
OME 927s would work well with the ARB alone, add a winch and I'd go 790s ( I had a ARB on mine for 8 years and ran 927s for 100,000 then went to the 790s for 60,000 then the JBA adjustable coilovers )
But 927s are rated at 400 lbs , stock is 310, 790s are 500 lb springs and you'll know they are heavy duty for sure
But with that bumper I would not go any less than the 927s
NOW with that said the Ironman makes a good spring which I've also tested and ran for a while, their HD spring will work with the ARB and gives you 2.25 inches of lift
This is also assuming you have a gasser and not a CRD
Any upgrades I would also do the rear since the springs and shocks have to be toast as well
Bilstein makes a good shock , Ironman are a little bit longer for front shocks than Bilstein or OME

It is a gas motor. Thanks for your quick reply. I will also look in to the ironmans.

I installed load range "C" (JEEP014-C) Ironman springs front and rear (JEEP015B) along with Bilstein shocks. They are very good springs and I am super satisfied with their performance. The combo actually rides and handles better than the OEM parts. Plus price was less than the OME springs. Got them from JBL, best price.... :D
Running 245's with no contact or trimming required...
