Suspension Tweaks

As most of you know I have the 4" Superlift on my Commander. Of course, I can't sit still so I am constantly researching and trying to find ways to enhance or improve that lift kit. This weelend has been no exception as I have made various tweaks to the front and rear suspension.
1. Replaced OEM ball Joints with a heavy duty adjustable ball joint.
2. Replaced OEM front struts with Bilstein struts
3. Replaced OEM lower rear control arm with adjustable control arm.
4. Replacing rear shocks with 12" Travel Bilstein 7100 Reservoir Shocks. (in progress)

Still tweaking and adjusting but here are a few before/after shots from completed work so far.

So far the control/handling on the front end has improved greatly. The new struts are valved at 166/121. I am pleased thus far but still need to drive up into the mountains this week for a real test.

Yes, I did on the front. The upper control arm would hit the upper part of the knuckle at the ball joint when the tire would drop. And as you can see the OEM ball joint was pretty beat up by the angle. The rubber boot was shredded.

awesome.... I need to do the same. What is your source for the ball joints and rear control arms? Did you actually adjust the length at all?

The ball joint is a SPC product:

The rear control arm is a BDS product:

I used the rear lower arm to adjust and center the rear wheel. On my setup the wheel seemed a tad closer to back of wheel well. It's a tweak in progress.
Can't wait for my 7100's to come in. They are suppose to be in this week.

The stud on the ball joint is not as long as the stock one. That gives more clearance for the tires. Thanks for posting all of this phunkeydude.

How hard was it to change the struts? The other parts don't seem too hard.
