What's a good starting point to get me close? I'm putting on a 4" Superlift on a 4dr and I bought adj. uppers and lowers for the front.

And WOL, if you're reading this, I scanned your Currie writeup looking for the info and I believe you may have listed the stock control arm lengths instead. Very detailed writeup, BTW. Thanks.

 

According the Super Lift (Black Diamond made by super lift), the distance between the center of the holes should be adjusted to 23-1/4"

I just put my lower front rock runner arms in this last weekend. This is stated in the installation instructions that came with the arms. Be sure that the swivel part of the front arms are closer to the frame. I made the mistake of putting the swivel closer to the axle and had to redo. What a bummer. You might have a hard time lining up the bolt holes. Change arms one at a time, then use your floor jack under the axle to move the bolt holes back and forth. Worked for me. GL

 

LOL!! They are but that's what Currie recommended so that's what I included in their write-up. Depending on how much caster you have now and how much more you need, you will most likely need to shorten them a bit.... maybe 1/8"-1/4" from stock.

 

Thanks.
