Mine came with a 2.5 leveling kit. I called Rough Country and they sold me the rear springs and sway bar links from their 3.5" kit a la carte. Raised the rear exactly 2" and it's perfect now.

Do your 2.5 rear springs required any shock relocation?
My boat has roughly 300lbs of tongue weight and my JT has a front level kit.
Don't want it pointed at the sky when towing, but am not too enthused about installing bags.
