I installed my RC 4.5 X Series lift. When putting controls arms in I noticed the LCAs hit the shock mount area. I went by the instructions RC provided as far as control arm length. Does anyone trim or modify the shock mount area where it hits the control arms.

So I just did some research on control arm length. RC reccomends 15.5" on upper control arms. I found a chart that says 16.5" on UCAs. If thats the case im way off. Opinions please

When I was still running short arms mine hit in the same spot. I just notched the bracket with a grinder

Your LCAs don't have a bend in them?

shum8

No they do not. This is primarily a street truck but I noticed this right quick. Im def learning alot about Cherokees for sure. These type things will def be considered when building my second one. I have yet to drive it since the install but it sure doesnt seem like its gonna have much flex. Even for a short arm.

Are they adjustable?

I have those, flip them around so that the flex joint is at the axlw, you will have more clearance then.

Exactly....

Control arm length charts are for reference only.

You need to pay attention to what your actual castor angle is and adjust accordingly. Don't set your axle up based on some chart.

Exactly there a starting point to get you up and running.

I guess my question is irrelevant until i get it all line up??? Correct? So where do I start? First off. I have a transfer case drop kit. Do i install it first then start checking alignment? There is an old school alignment place nearby. Just take it to them and see what they say?

spaz_22

is that with the tires on the ground or is the frame supported and the axle suspended? suspend the axle and see if that's what is limiting your flex. Looks to me like you have some room. how much lift do you have?

This is what I did and they still hit a little

Yes tires are on the ground. First off. I think pinion angle could be better. If i install transfer case drop it will help that. This is just me thinking and i am no means an expert at this. I need to center axlle right to left by adjusting the track bar. Then should I ensure that top and bottom coil mounts are in a vertical line(plumb). With weight on axle of course. Then roll axle with UCAs to get axle roll correct. I know LCA brackets have a factory adjustment in them. But it seems that is a minute amount? Its a 4.5" lift ao I know this shouldnt be extreme

I will say. I feel like Ive wasted my money on adj control arms. A short armed street truck with minimal time in 4wd. Doesnt need them. Thats my opinion thus far.
