Hellbent Steel is a good option and is the kit I have sitting in the closet waiting to be installed, granted I have a 1500 though. Maybe more CTD guys will chime on on what they're running. Possibly even check to see if Bilstein has an option for you, had the 5100 adjustable shocks on my 3rd Gen 1500 and was great! Just a little more to the install than just a spacer like the Hellbent Steel is.
