I Need Control arm ADVICE!!

[NPE102414]

I have a JlUR with a Mopar 2” lol, more like 3.5” lift and trying to get some more caster so I’m replacing thenLCA’s. At the moment because these damn thing are so expensive I can only do me more set. So my question is, where is the money better spent, front uppers, rear uppers or real lowers? My mind is telling me rear lowers for more adjustment, what do you guys say and why?

If you put on lowers in the front then I’d put lowers on the rear.

I'm not sure I fully understand the question. Only the front axle has caster, so installing any rear control arms (on the rear axle) will not change caster at all. Adjustable rear control arms can be used to adjust pinion angle though, but that's an entirely different topic.

Either adjustable upper or lower (or both together) front control arms can be used to adjust caster. But if all you want to do is adjust caster, here is an inexpensive option that utilizes the factory control arms: https://www.4wheelparts.com/p/fabtech-alignment-cam-kit-fts50622/_/R-BKBN-FTS50622

Yes I understand caster is controlled by the front control arms that’s why I purchased LCA’s. I’m trying to upgrade all eight control arms but can’t afford them at once, I’m building my suspension in stages, so my question which set would do me more good after the front LCA’s. I would never use Kim bolts or any type of chick really were just caster, I’ve spared no expense on this jeep and don’t plan on starting now.

Front adjustable uppers won’t do me any good because I already have longer fixed front lowers. I would’ve loved to of gone with uppers but none of them get short enough to adjust caster past 6 where I currently am.

I’m sorry, I’m confused now, do you currently have front adjustable lower control arms, or the fixed arms that comes with the kit?

If you truly are at 6 degrees what is it you're trying to remedy?

It’s at 5.9, and 6 but I feel a little more caster will help with the slight wandering and my never ending quest to tinker for the best possible ride. I hate it having control and adjustability. So, my only question is whole building this Jeep in stages, where will I find the most if any benefit outside of Front LCA’s. I will eventually replace all eight with adjustable control arms, But doing In stages of affordability.

Have fixed front lowers currently but ordered adjustable front lowers.

Have fixed front lowers currently but ordered adjustable front lowers.

Ah...got it.... then it really doesn’t matter which ones you get next, but I would get rear lowers next just to keep from getting my ass chewed by my ocd....lol.

I also feel the these fixed lowers moved my front wheels out to far. What do you think, is it just me?

lol, I have the same ass chewing ocd as you lmao!!

I just installed both front upper and lower adjustables today. Synergy. They are heavy duty and I really like them. I am also doing the tie rod and drag link, already did the steering stablizer and track bar. I have also done the rear track bar.

I am concentrating on the front now, maybe in a couple of months I'll do the rear control arms. Maybe.

Busy boy, I like it!!!!! I like Synergy and even bought a set of uppers but decided to return them. I settled on the Teraflex Alpina IR control arms. As far as I’m concerned Teraflex makes an amazing product, fit and finish is always perfect, and they are heavy duty with a lifetime warranty. Plus I like the IR bushing better then what Synergy uses. I already have a Teraflex IR front track bar so I’m staying in the product line. Hopefully they get their rear track bar, drag link and tie rod to market soon. I’m also eagerly awaiting their hinged Alpha tire carrier that’s supposedly coming out soon too. I really love the attention to detail they put into their parts, makes me all warm and fuzzy lol. I saw a video of a guy screwing down the pinch bolt on a Synergy control arm and the powder coat just chipped off in large chunks. Sorry, that shouldn’t happen with a premium product in an upper price point, corrosion is will be an issue. That would never happen with a Teraflex part.
