Adjustable control arm upgrade

[HappyGladiator]

I just installed Synergy lower rear control arms to correct pinion angle after a 2 inch lift. I found out that it's the upper arms to adjust the pinion angle so now I am getting the uppers rear to match and adjust. Thinking of adding the fronts lower and upper to have the full adjustable ability and to possibly aid in flex and ride due to the Synergy bushing . The arms are a real plus over the factory in quality. Am I going to notice any difference if I have all 8 arms other than they look cool? Does anyone have them?

You'll certainly see an improvement on the front end with steering and handling if you push the caster up to about +6.5. You could have accomplished all of this with the factory arms and correction brackets front and rear, but you've gone and spent all that money now, so you may as well keep doing that. LOL

Yep, its full speed ahead. Support the economy with American made. We'll see how the Dual Durometer bushing is and if it's all its cracked up to be. Lots of them out there on different lifts. They should be great at the mall speed bumps,,,LOL.

Also, wondering what the thoughts are of Synergy suspension components. I don't see them mentioned much here. I really think the quality is top.

You can adjust the pinion angle with the lowers just fine, it will just shorten the wheelbase a tiny bit. None of this is really necessary at 2" of lift.

For the front end it os the opposite, adding only lower adjustable control arms will allow you to get better caster angle by extending the arm which will get the wheel center back to stock location.

I wouldn't do all 8 arms unless I was going 4"+ lift or was serious into going offroad and wanted to increase articulation and durability. The factory control arms are actually pretty nice, much better then older jeeps.

Keep in mind the factory control arms can achieve enough flex to require new driveshafta Nad break lines. If those weren't on your to do list already I would stick with just doing the lower arms. The upper arms also see the most stress under tension, which is where they are the strongest... less reason to upgrade. As well as the fact they aren't going to be hitting obstacles.

The Synergy adj arms do not get shorter than stock factory arms.

Good to know.
