Got all my suspension parts.. i think

[Chriswlbr94]

Morning all,

I just received my upper control arms to accompany my bilstein 5100 (fronts and rears) and some eibach 3" lift springs. The UCAs are rough country (I wanted the more affordable option) and the instructions state to drill the tapered hole a bit to accommodate the new ball joint. I was planning to do this whole install this upcoming weekend, but the drilling part caught me a bit off guard. Has anyone installed these ucas on their truck? Im at work now, but can add a photo of the instructions when i get home later, for clarity. Mines a 2021 2wd with steel knuckle. Thanks in advance.

Drill how? Use a tapered drill bit????

Best,

I will have to double check the bit size, but it was not a step/tapered bit. Just a single straight size. It sound scary and foolish to do that ?

Yeah... no. There's no way I would attempt drill any hole to accommodate a ball joint. IMO, I'd send them back.

Unfortunately I may have to do just that. I'll call the stage3 customer support to ask before doing so. Just incase it's not a necessary step.

I probably wouldn't try it. You may have to look at a more non budget option for UCA. What's strange is that their website says it's for 4wd only where Icon lists their UCA as 2wd/4wd. I don't see what the difference is for RC

 

[DukeCanBuildit]

That would be a hard “NO” for me.

 

[Dr3wDrop]

Well that is irreversible at its finest. And that's coming from the guy who installed a diff drop kit that involved cutting off factory components.

 

[RangerPNW]

Yeah...I'd return it and get something else... Rough Country is extremely cheap for a reason... Do yourself a favor and get an UCA from pretty much anyone else. Icon or Grimm Off-Road would be my recommendations. More middle of the road pricing, and both appear to be very high quality. Have an Icon one myself, its been great so far.

The moment you have to modify a suspension part to make another part work is where I draw the line. Part of why I like the Old Man EMU Suspension. Didnt have to modify the suspension to maoe it work.

Just drill them out like the instructions state. The removal of material is minimal to clear the threads for the stronger balljoint. The taper doesn't lose any strength and you can still revert to the foctory arms without any problems or loss. You need 3 inchs of lift minimum to use the RC arms and your alignment will be narrow stance.

Thanks for your reply, have you used these UCAs? Just wondering if you're speaking from experience.

I ran these arms for a while and reverted back to stock arms as I don't have enough lift to warant using them and keep my alignment where I want it. RC arms work best at 3 1/4 to 3 3/4 inch lift, but you need a diff drop and your steering /lower ball joints aren't running at a good angle for longevity.

I see, thanks for that info. I'll probably be looking close to a 3.25 lift since I just have a 2wd, I dont believe I have a diff to drop in my case. But lower ball joint/control arms may be recommended in the future for this application?

Honestly I would consider just maxing out the 5100s at 2.5" and call it good. You're going to be paying a chunk of change for another 1/2 - 3/4 inches
