About to install RC Control arms on Rubicon
as the title states im about to install these arms on my 2 door rubicon.
these are all adjustable so im needing a guide to set the lenghts to center the wheels in the wells.
ill be running a RC 2.5 spring lift, 35x12.50r17's, adj track bars, trimmed or flat fenders, and i will be trimming body seam and rock rail gently.
ive read where the lowers need to be lenghtened 3/4' front and 1' rear and also have read to lenghten all of them those respective lenghts.
some insight from the JK forum would be greatly appreciated!

Set front lowers to 23 1/8 (make sure the lengths match up) this is what i did
http://s1031.photobucket.com/user/ke...eudjp.mp4.html
Now Mount them up with the jeep on the ground (ride height)
Use a jack under pinion to take pressure of the uppers and remove.
Now raise/lower the jack to hold the pinion at +2°
Take one upper and bolt the frame side up, then adjust the joint out to the axle mount. (You want both bolts to slide through easily)
Now take the other arm and do the same.
Drop jack and measure pinion again.
Tightening the bolts, jam nuts is the last step, just make sure you are at ride height.
Set rear lowers to 20" (should be fine at 2.5")
Same steps as the front. Mount lowers first, then you will have to use stands under the axle and remove the tires to get to the uppers. Use jack to take pressure off the uppers and remove them. Now use the jack to hold the pinion -1 to -2° below the shaft. Match mount the uppers like you did in the front. Recheck pinion and tighten the bolts. Lower and go get a alignment to confirm caster, thrust angle etc.
Good to go .. Good luck !!!!

1/4 front and rear. You can go more in the rear but the coils will bow, and the swaybar may need to be moved back. It Really does not take much to center the axles.
