M at about 4-4.5 inches of true lift by now and my tires are quite pulled back. I would really like to center them back up, other than adjustable control arms, what else would be necessary so I can do this the right way. The fixed control arms have to go.

 

You'll need a longer drive shaft too

 

You don't need a longer shaft for a 4.5" lift.

Adjustable control arms will get your axle recolated without any additional parts.

 

CAD brackets or long arms..
adjustable CA's will help making adjustments, of course.

 

I just put on RC's adjustable control arms, they're super beefy and totally worth the money. I was running fixed control arms and after I threw the adjustable ones on my axle came a little more forward which is what I wanted.

 

I'm installing my RC's X 4.5 lift tomorrow never done one anything dire I need to know. What about control arm adjustment? any help would help

 

He is wanting to move the axle forward, hence a new drive shaft

 

I believe he just wants to regain the lost wheelbase and get the tires back to their proper position.

I may be mistaken though.

 

He's still on stock control arms, same ~15.5" distance from body to axle. If he wants to recenter the wheels in the well (the reason for adjustable control arms) he will have to go to ~16.5". That gap gets added to the driveshaft too.

 

Cant the front drive shaft extend a little? Mine did when I installed the adjustable arms. Had some grease ooz out when I moved the axle.

 

Not quite. When a lift kit is installed the body moves upward pulling the axles toward the center of the rig.
Adjustable control arms allow the user to push the axle forward to maintain steering geometry and wheelbase.

 

And he's on fixed length, not necessarily stock arms.

 

Ahh I see, but the front drive shaft usually doesn't ever need to be changed like the rear one correct? Guys throw 6.5' lift on all the time and never touch the front axle.

 

How do I figure out how much I have to adjust my new lower control arms? I don't know how much lift I have but its not a lot. My stock arms don't cut it and I want to place the axle where it's intended to go.

 

Rear shafts are generally replaced because an SYE was installed.
