Which front coils for 5.9 magnum swap

My brother and I did a 5.9L Magnum swap into his 97 TJ and now the front end is sagging like crazy. What coils can we swap into the front to lift it back up?

The current setup is...
front: 2006 rubicon coils with 2"BB (about 2" height between fender flare and tire)
rear: original jeep 2.5L coils and 2"BB (about 4" height between fender flare and tire)

We tried the v8 front coils from a ZJ but it made no difference at all compared to the front rubi coils.

What are your suggestions? We prefer junkyard swaps. Thanks

That's odd, my front end sunk maybe a 1/2 inch, but I have aftermarket coils. I think it's only like 100-150lbs more than the 2.5.

You're not going to find much in the way of JY springs that will lift you more than ZJ V8 springs. I do remember something about F150 coils springs. DO a search on Google "Jeep f150 coils", that should get you some info.

The magnum doesn't weigh much more than the i6. Like 50lbs difference.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.

Now that I think about it, before I replaced the rubi coils on my jeep they were starting to sag just from the weight of the winch.

I have heard that the hemi weighs in at about 50lbs more than the IE6 and the hemi is 50 lighter than the magnum.

Looks like the best route to take is some heavy duty front coils. Pcoplin, what coils are you running?

I'm using some custom wound springs my buddy had made years ago. I wouldn't hesitate putting whatever coil you like, just make sure the rate is on the higher side. I would go with Currie or OME myself.
