Adjustable rear upper control arms?

Djeazie · Mar 30, 2014

Does anyone make adjustable rear upper control arms for our trucks? Or a way to adjust pinion angle on our lifted trucks?

Wouldn't the pinion turn up naturally as the rear drops?
I haven't looked under there at it much but I would think it would.

Contact RCX and they'll send you some. There was a huge thread on Forumz about people having issues and they sent out adjustable control arms for them

Trying to stay away from RCX with this. Im not crazy about the bushings they use. Feels to squishy. I dont remember where I heard someone having issue with Spohn.

Free is free, especially if you need them. They shouldve been included in the kit anyways. Plus I think they use Spohn for the adjustables anyway.

You can try using your stock upper control arm. I think its 3/8" shorter

what are you trying to do with the pinion angle? bring it up or bring it down?

Rcx is building me a set to fix my issue. Now, how do I set them up to get rid of my shudder?

Man I talked to RCX a few weeks ago about adjustable rear control arms and they told me they don't make them and have never made them...

Djeazie · Apr 20, 2014

They said to me too. But I told them bs and they finally said they would custom make a set.

What is the issue your having causing you to think you have a pinion angle problem? Or did you measure the degrees? Reason why I ask is because me and another member both thought we had a angle problem because the truck was making a clunking noise from coming to a stop and taking off and also when the truck is in reverse. We both came to find out we just needed to tighten the rear upper arms and it solved the problem for both of us.

I have a shudder upon take off. Other members had this same issue and it was fixed by adjusting the pinion angle.

When did they say you should receive them?

Djeazie · Apr 22, 2014

Soon. They are supposed to ship this week. Just not sure how to set them up to eliminate my shudder.

Hopefully they are the ones that can be adjusted while on the truck. Thatll make it easier. Local jeep shop says its just trial and error when setting the angle with control arms...
