That's going to depend on what all was included in your Pro Comp Kit. While a set of Boss Coilovers and an Add-a-Leaf kit will get you the actual ride height, to support that ride height, you'll likely need extended brake lines, a driveshaft spacer for your main driveshaft (assuming the kit didn't come with one, and even then a larger one may be needed) a brake line drop bracket, and possibly longer U-bolts depending on how much thread is left on the ones for your lift kit. Your best bet would be to call us directly at 1-877-578-2433 so we can get more specific with what your kit came with and what you may need.
