They look pretty similar to Omelet's UCA'S.

If you are doing a 2-3" lift do you need these UCA's or can one run the stock UCA?

Thank you very much....

Does anyone know why these aftermarket UCA's are a pretty penny??

Im in the need of new Balljoints and confused on which to buy. Trying to figure out if it will be worth buying a set of OEM or Aftermarket.

My jeep is only for the snow and for Beach driving. So I dont need crazy suspension like most.

I am kind of doubting those things are going to fit very well. Looks quite big/bulky and would limit up travel and down travel. Mine are close to contacting and not nearly as large. Plus I think mine look better and I use a 1.25" uni ball instead of a 1", aka more misalignment.

Hey, just wanted to let everyone know I received a reply (like a week ago, but I just saw it, my bad) from the owner of American-Motorsports and here it is;

"Thank you for your interest in American Motorsports products. The upper control arms are made from .125 4130 chromoly plate that is water jet and cnc bent and fixture welded. The upper arms give you more clearance around the coil. It is a tight fit but it clears. It allows for up to 2-3 inches more wheel travel over stock this all depending on your coilover application. The ball joint is replaced with a more stronger uniball that bolts to the spindle with a tapered sleeve. The unball allows for more degree and less stress when lifting your jeep front end. Minor trimming is required to the stock inner fender wells to allow proper articulation. We us urethane bushings or heim joints to mount the upper control arms. I prefer the heim joints over the urethane bushings because it allows for more adjustment of castor and camber and prevents the lower arm running out of adjustment. All parts are included to bolt on these replacement arms. Cost is 699.99 for the urethane bushing arms and 799.99 for the heim joint arms. Let me know if you have any questions Thank you Brian 760-802-0010"

Little pricey, but they look awfully neat!

Those American Motorsport arms were designed for a WK running a stacked lift (OME + Daystar) and push the upper balljoint out further. When running a proper 2-3" lift these vehicles need the upper balljoint to be pulled in closer than stock to get alignment in spec. I wouldn't spend money on those AM arms until someone with a normal lift posts some pics and alignment specs. $.02

Okay, so the verdict on this seems to be that JBAs are the best choice.

However, the price difference between JBAs, RROs and stock is pretty substantial. My ball joints are taking on a pretty nice chirp and they need to be replaced. This is a daily driver with a 2" BB and some duratracs.

So my question is: If I just go with stock UCAs will I end up burning through them so fast that I would just be better off getting the JBAs now? Or can I go with stock UCAs and actually get anywhere near regular life out of them? I know the JBAs are preferred but for a truck that spends most of her life as a DD are they really needed?

You'll be fine with stock arms. JBAs are a really nice upgrade but with just a daily driven BB the cost vs benefit for you may not be there.

Thanks a ton! I'll probably go stock just to get them replaced and then go JBAs in the long run when there is a little more expendable cash floating around.
