Pretty much everyone is keeping rear shocks. I saw a thread awhile ago about someone who found Bilsteins that had the same valving as the Cognito's, and was running them on the rear. I'm about to do the mod myself, and I'm going to just use the stock keys. From what I've read, it's a waste of money to buy a leveling kit. Just reindexes where you start. Not really a point unless you are lifting above the "leveling" point.

 

Nice job Josh!!! Right on thepoint brud. Like the man said, no need for a levelling "kit", spend the $$ saved on the shocks.

 

Thanks...oh and search > ME haha
