so after looking at all the suspension parts on my new to me ‘13 JKU I noticed that there are no aftermarket control arms or drop brackets on it...which would probably explain the floaty feeling I’m getting over 60mph. I’ll probably just go with drop brackets for now(for cost). What I don’t understand is do you need them for the front and rear? Or just the front? Most kits only have 2 brackets.

 

Can you give us details on what you have added to your jku the reason you want brackets? Typically they're only front though.....unless you get at 5.5"+, then Metalcloak offers a rear as well.

 

just bought the Jeep last week....already had a RK 4in suspension lift on it. Jeep drives great unless you get on the interstate above 60mph or so then it gets an uneasy feeling in they steering. After doing research on drop brackets for the control arms, I believe that would fix my problem

 

Get some pictures of the front end geometry and control arms. This will help the rest of the forum members here help you out with recommendations.

 

The rear DS on the 4dr's has CV joints at both ends. Even at 4" of lift, the rear is pretty forgiving. You likely just need some correction up front. Think I recall mentioning this in one of your other threads, confirm you don't have cam bolts in the front axle lower control arm brackets.

 

Slow down a bit. Understand what the problem is, and specifically what components you have, before indiscriminately throwing new parts at it. One easy thing you can do is to go to RC's website, find that specific lift, and click the link to the Install instructions. That'll show you what/where/how of the parts that were included and should be installed. Another thing to do is to call around to a few alignment shops, some will offer free checks where they just print out the 'before' specs without actually changing anything. Post those numbers!!!

The pics in your previous thread were RC, just want to make sure were looking at and thinking about the right components.

The kit currently shown on their website comes with Cam Bolts for caster correction, not brackets or arms. (the numbers for caster printed on the alignment sheet will tell us where you're at currently. Assuming you do have Cams, it could be that they are not adjusted correctly or have slipped.) Check the install guide, but on your front control arms, look for bolts that have a washer offset to one side instead of the washer being centered like normal. Should be fairly easy to see.

Caster is only for the front, it is basically how much your axle rotated due to the lift (the pinion, where the driveshaft connects, rotated higher, which lowered the caster. Some form of correction is then used to lower that pinion again, which raises the caster back up). For the rear, the reason to adjust the pinion would be for alignment of the driveshaft, to lessen the angles those joints need to work at. Concentrate on the front end before thinking about throwing parts at the rear pinion angle, it should be ok on your longer wheelbase 4door.

As you can see in the install guide, that lift comes with a Drop Pitman Arm. After the lift, the draglink and front trackbar operate at steeper angles. Using the longer pitman and adding a trackbar bracket is one method (the cheaper and much less preferred method) of flattening those bars again. You might see a theme going on here. Cam Bolts are the cheapest and much less prefered form of caster correction, same as a drop pitman. I think it was mentioned in your last thread to do a little reading on Draglink Flips instead, as many previous members have improved the quality of their ride after removing that drop pitman and swapping to a flip...

If you aren't sure that the components you are looking at on your jeep is actually what is pictured in the Install guide, just snap some pics and post them. We can probably help with the identification.

Here are the links to the lift (I'll assume this is what is installed?) and the Install guide:

Just got home...thought I’d take a few pics of the front suspension....no sight of cam bolts you speak of.....looks like oem control arms and hardware to me....only thing not oem is coil springs shocks and track bar.

 

Seems like there were some interesting lift choices made by the previous owner. Is there a raised trackbar bracket on the rear axle at least?

If you find an alignment shop, the caster numbers will verify the cause of the flighty steering, but sounds like you are on the right track with adding CA drop brackets or a set of arms. (my money was on cam bolts that had slipped...) If there is no rear trackbar bracket, you will want to address that as well. Since you are indicating that there is no steering correction (drop pitman/front trackbar bracket), may as well wait for the outcome to the caster question before deciding if you want to flip the draglink.

 

forgot to mention that the rear suspension is completely stock also....including the trackbar...told my wife he was either a cheapskate or got scammed by a dealer.

 

That's a rough country lift, not the rock krawler. The rough country lifts are a little notorious for being incomplete. The ride after the lift may have been why the person sold it to the dealer.
