I went with the springs only. Many around here prefer the Kore springs. I have had no trouble with the Superlift product.

Personally, I would not want add a leafs in the rear.....mine's rough enough as it is. Plenty of room to clear 35's in stock form.

I would want the aftermarket lower control arms though. After adding the D25 springs my tires cycle back to just contact the trailing edge of the passenger fender at full compression, not enough to cause any damage, just make noise. Extended control arms would address that. I'm going to add some to my set up. Probably these unless someone has a source for the Skyjacker version.
