Question RE 4.5 lift and tire size?

Okay, so i know the other details as far as extending break lines, new tie rods and drag links, and re-gearing. My Jeep is a 2004 5-Speed Sport running a Dana 44 in the rear geared at a 3.73. My wheels are MT Classics and are 15x8 with 4.5" of backspacing currently on 32s () and a 2 1/2 RC lift. The lift I plan to purchase is the RE 4.5" Super flex lift. I know they tend to sit a full net 1" higher than advertised, thus my questions.

1) With running 35s on this lift, will I have any rubbing when tackling moderate to extreme trails?

2) As a moderately adept DIYer, I plan to do the install myself. Has anyone had any difficulties or problems while installing this kit?

3) Are the mono-tube shocks included with the kit worth the extra 450? Would an alternative such as skyjackers M95 Performance be a better option?

4) If I cannot clear these tires at 4.5", what would be a good budget boost kit or alternative lift?

And yes, my jeep will be used heavily off road and 35s will serve my purpose well. I just prefer to ask questions and do it right the first time if im going to do it at all. Thanks all for your input!

I have RE super flex lift 4.5 but I also put front tube fenders and a 1&3/4 front spacer to make the front 6&1/4 inch lift on 36 inch boggers. Never had a problem doing sum extreme off roading only when you turn and have a crazy flex the front rubs a bit. I didn't install it but the shop I took it to said those lifts are a pain to install didn't ask why. I suggest installing the front spacer for added clearance only 60 bucks. I also slapped on the RE extreme-duty mono-tube shock loving every bit.

I caution you to do extensive research on those RE control arms prior to purchasing the kit. Most guys will run the 3.5" RE coils and add 1" body lift to clear 35s. If you are dead set on this kit I would suggest purchasing a better set of shocks. An extra $450 for monotubes is nuts. Buy a set of Bilsteins or OME for $300. I just removed an entire RE suspension system from my rig and promptly deposited the standard RE shocks in the nearest trash receptacle. My new suspension system rides/handles significantly better than the RE equipment.

I run a 4 with 35's. If you are set on a 4.5 I would run at least 37's.

Yea I was looking at the Bilstein shocks but the 4.5 lift height is a pain to find accurate shocks for when you also consider it sits almost a full 1" higher than advertised. And CrazyHawk that's true of a Jk that's got far better fender clearance, not so much of a TJ.

Do yourself a favor and get in contact with a vendor named Kolak. He set me up with Bilsteins for my 4.5" BDS coils. The dude is very knowledgeable and will order you the correct shocks for your application and offer the lowest prices around. You will be able to find his info on jeepforum.

Here's mine, 4.5" super flex with 1" BL and 4.5" BS. With correct bumps tops u shouldn't have any problems, I now have metal cloaks so there's a ton more clearance. I had no issues prior though

I just purchased the kit with some customizing it with 4.5 front 3.5 rear. I got the Rubicon express mono tubes because they are actually Bilistien 5100s so u get them 150/200 less than buying it separate. they are amazing so far and the kit has not caused me any problems bushings still work i think they finally fixed the problem.

Order from 4x4 Group buy. u get a free SYE and driveshaft from Tom woods part of the deal for buying the whole superflex kit

Im on 35s now no problem with 3.73 just went up to 456 yesterday

BL's tend to bend the body of a TJ over time and especially if your going to be wheeln hard. 1"3/4 coil spacer is the best way to go!

Okay thanks. I got in touch with Kolak and he's gonna set me up with both. I plan on running spacers in the front anyways due to my bumper and winch. I guess I'll put 1 3/4" in the front and 1" in the rear. Thanks for the advice.

Could you possibly post a link to that kit? And what upgrades would you all consider to be a necessity with this lift and 35s? I know I'll need tie rods and the SYE kit/cv shaft. Anything outside of that? But I'm currently geared at 3.73 in a 5-speed with 32s and plenty of go. Think I could manage with 35s? Kinda on a budget so I don't plan on going over the edge with it until more upgrades. Just need it to be moderately trail worthy on 35s for the time being.

Heres the link
I ended up doing upper and lower adj control arms
since i already had a RE front track bar i asked to switch it out for an adj rear track bar
I also wanted a tummy tuck so i would have to go higher with a lift but gain more clearance, so i went with AEV Tummy tuck.
I got lucky and found a Currie on Craigs for half price a year old so i picked that up easy.
After 8 months the Gears were still in great shape and off roaded alot with it, I drove out to CO from SO Cal and the drive killed me so i decided to Throw in some 4.56 gears ill lock it and new shafts when things break down road but its got plenty of strength to handle it now

Wow that is a fantastic deal. Thanks! And yea I'm either going to. 4.56 or 4.88. I've heard both are good for a 5-speed. By the way sweet rig! I'm a sucker for white TJs.

That's my plan, I like how low 3.73 felt stock. I'm going to just sit with 3.73 on 35s till I can save the money to re-gear. I'm on 32s now and feels low so I think it'll be okay for the time being.
