Spacer lift + rake correction recommendation?

Anyone running the TF without new LCA’s on a Rubicon XR?

Given that I haven't done the LCAs, I can't say whether or not it's better. What I can say from personal experience is that *only* adding the TF spacers, with everything else under my Jeep bone stock Sahara, there was a noticeable improvement in driving/steering/etc over my stock configuration. I have not measured my caster with an angle app either, but you kind of have my curiosity piqued.

You definitely have some placebo going on.

Front is definitely lower.

What shocks are you running? If you've already added Rubicon springs and then add these spacers you'll likely need new shocks or extensions. Also pay attention to the sway bar angles and bump stops as you're starting to get into the realm where they need attention. I've seen a lot of people get lulled in by the price of this leveling kit and then realize they have to add a bunch more components after the fact. I would definitely consider adding at least the Mopar LCAs as well but my preference would be adjustable LCAs as your caster will be woefully low.

I also have the Teraflex spacer kit. The longer Mopar lift kit LCAs were not quite long enough. I used adjustable LCAs set to 1/8" longer than those in the Mopar kit. My rake is now roughly 6°. 1/8" makes a bigger difference than you would think.

I'm not buying the drove-just-fine-without-changing-LCAs. This falls into the you don't know what you're missing category.

The best thing is to download a free angle finder app and measure for yourself. You're looking for 5°-7°

I would think that you mean Camber is at 6 degrees, do both sides measure the same?

Caster, camber is not adjustable on a straight axle without shimmed balljoints.

You are correct Caster it is, I`m reading the story about the guys engine blowing up for the second time,

Not necessarily. I know that it's better than stock. That doesn't mean it's as good as it possible could be - just that it's better than stock.

If Stock is a 1, and let's say with LCAs, it'd be a 10. I could be anywhere from a 2-9. All of which are better than stock.

So explain to me how adding spacers did anything to improve your ride? Your caster is now lower, everything else is the same.

If dude says it feels better then who are you to tell him he's wrong??

I'm just over here believing in science, don't mind me I've also lifted a large handful of JLs now so I have pretty good first-hand experience with what each mod will do to the driving characteristics of these things.

When I first got my 23 JLU Willys XR 2.0T, I already had a set of Mopar LCAs waiting to be installed. I thought it drove fine when I got it, but soon after I went ahead and installed them (since I had them and the install was easy). Honestly, I didn't really notice a difference. I figured after all I had read on this forum, it was like a "can't hurt, might help" kinda thing, and the LCAs are actually quite inexpensive.

If elves had snuck into my shop one night and swapped out the LCAs and the next day I went to drive the Jeep would I have noticed? No. But I'm sure according to the numbers and alignment science there must have been an improvement somewhere.

Later I added 0.5" TF spacers all around. They were inexpensive, easy to install, and good quality. I did it both for looks, and to put a little more space under the front bump stop. Not enough lift to really affect the steering geometry. I think the 0.5" makes a difference visually, looks better.

I added the same to mine today due to front bumper and winch install.

I'm running stock shocks and Rubicon springs. The Willys came with the same shocks as rubicons so I didn't change anything there. I did end up putting in the Mopar LCAs when I put the spacers in. I didn't notice any difference in driving, but figured it couldn't hurt. Overall I'm very happy with the appearance and it drives same as it did stock.

No, he means Caster at 5-6 degrees. You cannot adjust camber but you can adjust caster with longer or adjustable control arms OR Geometry Correction Brackets are best yet.
Factory caster spec is low (under 5 degrees) to start so adding any type of lift makes it worse.
Spacer lifts are a great economic start to your lift and Jeep mod journey but it can also be a rabbit hole. When you start mixing too many other parts with them you end up with your caster and geometry all out of wack.
Spacer lifts are great start to get bigger tires on without messing up ride quality, but, as soon as you start adding bumpers, winch, armor, gear etc you lose that gain. If the plan is to go to heavier bumpers in the near future just do new proper springs to start with. Generally with all my JK and JL builds I have to put 1” taller springs in the front then back to keep it level.

Yea I did get my camber and caster mixed up
