IRO 3.5" benchmark lift & extras questions

Okay so looking at the IRO for my entire lift setup and have picked out what i think will work. I'll list it all below, but what I'm wondering is there anything else i need or would want or is a waste?

IRO 3.5 Benchmark[/URL]
-Nitro Shock
-New rear springs
Tenneco HD Steering Stabalizer
ZJ Rear track bar drop bracket
ZJ rear coil retainers

Total of $675 so far already a little more then i wanted to so keep cheap in mind.

Also shocks im okay with the nitros for the ride it'll be better then now...all 4 shocks are currently blown...i was a lil ruff one day

Then over summer or in fall I'm, going to do Addco sway bars from IRO.

would i need extended brake line or what would i have to do to mine now?

Also discos if im not really wheeling to hard do i need them? We got virtually no trails in WI i just know some people with some fields and forests.

Other than that I believe i covered it all but looking to make sure since this is my only driveable car currently.

You will probably need adjustable control arms to get your drive line angles in spec. Also your CV front drive shaft will not last long so you will need to eventually get that replaced with a U joint shaft. If you wheel over obstacles with the sway bar connected it will bend the sway bar axle mounts. You can just unbolt them though. You will also need a rear adjustable track bar eventually since the brackets usually break. Do not use the t case drop spacers.

"...keep cheap in mind" should never be used in lifting a ZJ.

I recommend the new IRO rear 3.5 springs especially if it ends up yours are sagging... with 100,000+ miles by now they likely will be. Go ahead and try the F/R coil swap first with your kit then see how it sits. Once I started adding my rear welded C4x4 bumper with tire carrier and gas can holder, mine sagged even more. Then try and put anything more than a small load of groceries it rakes pretty bad! The new IRo rear springs and 2" BB blocks fixed my issues. Good Luck!

I too am getting IRO adjustable control arm in a few months to finish it off...

I'm bout in the same boat. Here's what I'm looking to put on my stocker:

IRO F>R swap Kit: $450 http://www.ironrockoffroad.com/Merch...egory_Code=PFZ
Bilstein 5125 Shocks upgrade: $250
Adjustable Rear Track Bar from IRO $140 http://www.ironrockoffroad.com/Merch...egory_Code=PFZ
Adjustable LCAs front and rear: $360 http://www.ironrockoffroad.com/Merch...egory_Code=ZSC

Total: 1200

Just Empty Every Pocket. Probably going to end up replacing the rear coils, adding quick discos and longer front brake lines down the road.

what size tire are you running?

31s? gonna look funny on 3.5" lift.

2" budget boost. cheaper and will accopmlish running 31.

still want more? ok. start with the F/R swap. don't bother with new coils. spend that coin on shocks instead. or a front track bar.

should do lower front corntol arms at least if the bushings are shot.

Isn't part of the reason for a suspension lift to run bigger tires?

But 31's are just fine on 2" of lift, no need for 3.5"

Im currently running 31's stock.

So itd look wierd 31's and 3.5"?

Then if i wasnt to do a 3.5 and save out for it later on say 2/3 years how reliable are the 2" BB with say nitro shocks from IRO? Also any issues with the CAs or Sway bars?

Also someone said running sway bars crawling youd bend the axel mounts I dont necesarly see myself getting that deep in because id have to drive atleast 300mi to get there first.

BB's are fine, spring for bilsteins if you're gonna keep em around for a while.

Sway bar links should technically be longer for 2", an adjustable track bar in the front is also a nice to have.

Just drive to where you are going to wheel then unbolt the sway bar endlinks.

Here is how the sway bar endlinks mounts will bend if you wheel over uneven terrain. Ask me how I know that will happen. I didn't have the JKS when I did that.

hey I was just wondering why you say not to use the t case drop. I have one on my zj the po installed along with a 3" bb lift. I have not noticed a problem but would like to remove the drop for more clearance if I don't need it. do you think ill be ok with out the drop? im at about 4" lift 3" bb and upcountry coils fyi. thanks.

On my 95 I had 4.5"-5" of lift with no T case drop. There are guy on here with 6"+ and no t case drop. It's very rare that you would need one and you just lose clearance.

I just dropped 920 on the same kit.. Only I went with the dt8000s and added a rear adjustable track bar and their 2.5 inch exhaust since mine was leaking. I'm going to try the f<r spring swap first only because I've heard of instances where iros rear springs actually sit higher than 3.5. If it sags I'll just order a spacer or take a shot with 3.5" rear springs.. Once I order their control arm pack I'm thinking of popping a 1.75 inch spacer in from them anyway. Still undecided about their front long arm kit. But honestly, nothing will be cheap with a jeep. It's a full blown addiction. You'll always want bigger. I'm running a 2" bb on 31's now that I thought was sufficient .. Parked next to a friend with a 5.5 and my truck looked stock.. Hence the new lift that was ordered the next day lol.
