Rusty´s 3 inch vs zj spring?
Hey guys,i have a 99 tj sport that im thinking about lifting, i swapped the front bumper for the smittybilt src one(80lbs). originally i was planning on doing the zj lift and spacers on the rear but from what ive seen its really a gamble with that lift. some people get 3.5 inches some people get 1 and others get the 2.5 that i want. since i dont have that much money, i was thinking about getting the rustys 3 inch springs for the front (hoping that with the weight of the 4.0 and the bumper would be enough to bring it down to around 2-2.5, and just go with spacers in the rear. has anyone had any experience with rustys?

thanks in advance

also pics would be great

I just installed a 2" Rusty's lift. Excellent quality and priced right.

I will say installing a coil spring lift is much harder than the old leaf spring lifts.

do you have the 4.0 on yours? and did you happen to see how much of a lift you actually got?

Buncha guys have run that set up, if ya dig through my old threads there's a decent discussion about it. Either works, would go with what you can get cheaper and/or easier. The 2" won't be enough to get rid of the forward rake unless your springs are sagging a pretty huge amouint.

Yeah i just dint wanna take a huge risk with the lift and pay 75 for used springs that might give me to much or not enough. Also would i need new shocks? The po put brand new Monro shocks all around right before ibought the Jeep so they are still pretty great

I just installed rustys 3 inch in front and 2 in rear coils. I love the ride. I didn't measure the exact lift but the jeep sits level and looks great. You'll probably get close to 2.5 but if you get a little more it won't hurt anything. Keep in mind rustys does offer 2 spring rates 150 and 180 ( i assume your talking about the standard 150) and you could get 2 inch lift 180lb hd springs and you wont have any loss from your heavy bumper. I prefer the softer ride though which is why i chose the 3 in 150lb ones. You don't " need" new shocks but it will limit your down travel quite a bit. You could make a spacer for the front shocks as long as you make sure they don't too out and extend the bump stops if necessary. I would definitely recommend new coils vs zj coils especially if its only 25 more dollars or so.

Thanks APA that's probably what I'll do. Thanks for the heads up on the spring rate. What's a decent but not too expensive shocks? I've heard decent things from skyjacker

apaTJ 04-29-2013 12:28 AM

Funny you say that cus I bought skyjacker nitros to go with my lift. There may still be a 35 dollar mail in rebate on them at 4wd hardware. I paid about 180 for the set not including the rebate. The hydro ones are a little cheaper. I like the ride its better than stock. Many people will criticize them for not being made here but I think there pretty good. But you can get many different basic twin tube shocks for around 120 a set. I don't have experience with any others besides rough country and they were pretty stiff.

Just in case u wanted a pic with the zj swap I have zj front coils with 1in spacer and moved the stock front springs to the rear the 1 in spacer was to level out the rake and I have the 4.0

What year(s) zj spring fit? I have also heard of crown Vic springs being used anyone know the year span on them?

wa_troop 04-29-2013 11:13 AM

gbendezu 04-29-2013 01:13 PM

I heard the CV will fit in the rear but they tend to sag really fast
