I put the 422's on mine and I'm real happy with the ride.. They did make the front seem a little more spongey but that's something else to fix.. Bottom line: replacement shocks like the 422's will ride better than any bolt kit but they're $300 more.. Air will ride better than any aftermarket replacement shock but it's $800 - $1200 higher (depending on which system you go with).. Based on your posts above, I would say spend the $50 on the bolt kit and save your money for the air ride..

 

While Saintslax11's right about air ride, the next best thing is... what is it, Clint? lol
