Caster question

[Mrbizkitt]

I have a question about camber between the different model gladiators that maybe someone could answer. I have a Mojave to begin with which I understand is 1” higher than a Rubicon, and a Rubicon sits higher than the Sport. The higher you go it generally decreases camber correct? So with that being said I believe the control arms are the same on all the Gladiators which I guess would give the Mojave less camber from the get go. If I were to throw a 1” spacer lift on that would decrease the camber further. Would I be a candidate for the slightly longer Mopar control arms on or would that send me to far the other direction? I don’t know what the Mojave camber reading is to begin with. Thanks for any insight.

Camber is fixed on Jeep solid front axles. I believe you are talking about caster. After you lift a Jeep front axle you "should" have it checked for alignment. If you don't have enough caster you can add the longer adjustable lower control arms. "Camber" is how much the tire leans into the center line of car. "Caster" is how much the upper and lower ball joint center line is laid back. Hope this helps.

You are actually talking about caster, but yes the more you raise your vehicle the more you reduce your caster, mopar lift arms might help you out, but I would do research to make sure your arms are same as others.
Can’t answer your question on caster between sport overland and rubicon..
I would consider also purchasing control arm geometry relocation brackets as that is a cheaper way to adjust your caster then getting aftermarket control arms

Pretty sure caster increases with lift on our Jeeps? Upper arm is shorter, therefore rocking the top of the axle at a higher rate than the lower? Ive never actually measured before/after......

Ive seen people always referring to needing control arms to "Correct" caster after a small spacer lift, but if it actually increases so why do anything?

Caster decreases as you lift the front end, I lifted my JT 1.5” over Rubicon height, installed the Mopar lower control arms and they definitely helped and reduced the wander.

The Mojave and the rubi are the same height. The caster decreases as the height increases because the control arms pull the axle backwards. You get longer CAs to push the axle forward.

The either front can be used to dial in caster but the upper are most responsible for caster while the lower position the axle.

???‍ Caster is what I meant, don’t know why I typed camber. Tough get old, and I could swear I read somewhere that the Mojave sits an inch higher in the front then the Rubicon.

Maybe is that the lower control arm bracket is closer to the tube that it becomes more of an influence to reduce caster. Regardless, I'm 2" over stock on OE control arms and can't say I'd change anything. I seem to like things to turn in quick, so I run caster on the low side on all of my vehicles.

You have a Mojave?

To answer your question, yes you would benefit from the Mopar LCAs.
The JL and JT are woefully undercastered from the factory.
In fact, the JL people have been using the Mopar LCAs for awhile now to help reduce wander due to the low caster (and the old aluminum steering box), even in stock trim.
Granted, they only add about 2 degrees, but it helps a lot.

It does…

Thought I read it somewhere that it is!

I've lifted two JTs and a JL. In my experience they handle better when lifted 2 inches in the front. The caster must get closer to spec when the front is lifted I suppose.

Ground clearance between Mojave and Rubicon is only 1/2 inch. 11.1 on the Rubicon, 11.6 on Mojave, so is it only a full inch higher in the front? Or what am I missing?
