I have a 2012 JKU with 4" lift and 35 Toyos, but with no aftermarket control arms. To fix the wandering feeling while driving 45-65 mph do I just need to get aftermarket control arms?

 

less $
AEV -OR- RC Geometry Correction Brackets

more $
Adj CAs

 

Thats exactly why I did not go with the RC 4" lift no LCA's only Cam bolts. Cam bolts throw the geometry off and make your front seem flighty and floaty. I was going to go with Adjustable LCA's but the guys at the 4X4 shop said that unless I was doing some extreme flexing it would be a waste. The guys at the 4x4 shop said RC gets a bad name but they say its good for a starter kit.

 

Are u running 13.50 wide tires?

 

With 4" of lift, adjustable arms would be your best option. As mentioned, you can run drop brackets if that better suits your budget. Either way, your handling will improve greatly.

 

My 3.5 inch RC felt the same way. RC LCAs fixed the problem. I don't like the brackets and if you look at price it's not that much more for adjustable lowers. The geo correct brackets run about 100 bucks. I bought my LCas through a company tht offered 10% off for forums members and free shipping. That made it an easy choice.

 

Looks like ill start saving for arms. Any suggestions for qualify for a lower price?

 

get RC.

designed for your system already. Also, you will need a cam bolt delete kit from poly performance. or something similar to that. your mounts are rectangular now for the cam bolts, these will have to be welded into place to fix that. they are not expensive but don't forget them.

 

Are you saying that you have to weld in new mounts for running adjustable control arms. I've been looking to replace mine also.

 

Yes, if you have can bolts already, you will have to weld these in to make the holes round again.

If you are stock, then your fine.
