Default 37's and 3.25 Lift Issues

Hello and greetings from the NW. I may have jumped the gun a bit with moving from 35" toyo MT to 37" toyo MT. I am looking for any insight I may be able to get from the vast knowledge base of the JK owners.

First let me say that I'm sure I will be scrutinized about my current set up and 37's.

Set-up......
a. D30 with NO Gussets or reinforcement. On my to-do list and has moved up the priority list to #1.
b. I do have 5.13's
c. Automatic
d. No drop link steering kit.

I understand completely how everyone has their own opinion and I respect that. With saying that, I hope to limit the should've(s)/could've(s)/would've(s). haha.

I currently have a FabTec 3.25" lift with a trac-bar relocation bracket. It worked extremely well for my set up with 35" toyo MT's. I didn't have to trim anything but my lower valence under the front bumper. Well, without my fiance' knowing I went and bought 37" Toyo MT's yesterday. As you can probably figure out I went and bought a sawzaw as well haha.

So getting to the point in my post....
1. How can I get more lift? I know the easy answer is buy a lift kit larger than 3.25". I would like to get another 1.5" of lift to alleviate rubbing my rear fender wells. (See Below). Can I just rip the fender wells out?

Could I use a larger spring with my lift? Body lift is an option but don't know if I want to go down that road.

2. Can pucks or Spacers be used in conjunction with my fabtec lift?

3. How do I go about re-centering my Rear Axle? Is this done with Control arms or a track bar?

2 options. You can trim your fenders using your new sawzall!! You can add spacers on top of your coil lift. You could do both. The rear trackbar would center your axle from side to side whereas the control arms would center your axle in the fender well.

Default Sawzall vs. Sawzaw.... haha

SawzaLL.... Got it. haha. Is there a method to this madness with Control Arms? Say that I had to do this in phases...... Should I do Uppers first or Lowers First in the Rear?

I will put spacers on next weekend. Thanks for your reply.

Cheers

Did your current lift come with new control arms or are you using the factory ones? In my opinion, any lift in the 4-5" range should have all new control arms. And of course, adjustable arms are the best so you can dial everything in properly.

I think if you went and put spacers on top of your 3.25" lift springs and did nothing with control arms, you would end up with a poorly driving/performing Jeep.

get rear uppers first. It allows you to move the axle back slightly while rotating the pinion up. The ideal setup would be adjustable uppers and lowers to dial it in, but uppers are fine for the time being.

If you have that lift and add pucks, you will need lower front lca's. Frankly, you will be glad you did,the drive will be improved. As for other options, cutting your stock fenders, or buying flat fenders. One other option is a body lift. This would not effect your current lift, but give you the extra lift you need to clear the tires.

adding pucks is what most guys do to gain and inch or two. Very common. It seems to me like your lift netted less than 3.25" to be honest.
Also, what is the back spacing on your wheels? You may need to go with something with lower BS or add some wheel spacers to alleviate some of the rubbing.

My lift didn't come with Control Arms. I'm gathering from what your saying that if I were to put spacers on top of what I already have it would most likely push my rear axle even further forward with the angle of the lift.

Thanks for your insight.

Rear Uppers are going to be first then. Been looking at Teraflex for quite sometime and now is not the time to be trigger shy.

I would have to agree with you in regards to my net gain in my lift. When it was installed (Yr ago) it looked much bigger. I wish I would've put a tape measure to it to see if any sagging has occurred. Pucks will be added to account for the rake (more apparent now after the lift has settled over the course of the year). So I'm thinking 1" front and 1.5" rear with the Upper Rear Control Arms first.

My wheels have a 4.75 backspacing. So would this measured backspaced wheel cause rubbing? I made sure that the inner tires didn't rub the stock control arms.

Again, thank you all for helping me out through this transition to 37's.
