I am looking for a 2" - 2.5" leveling kit. Rancho and superlift have lower control arms that come with there kits... Do we need the arms? Which kit do you guys have and do you like it?

 

I went with the Rancho kit for my 03 - seems to work well.
On my old 02 2500 I put on a procomp kit - no control arm - just spacers & new shocks - Had 285s on at the time - did not rub - after install - the 285s rubbed on my nerf bars - so mutch for 315s. Without the longer control arm your tire will be further back in the wheel well.

 

That is what I expected that it would also change pinion angle too.
Thanks guys I appreciate the info thus far...
