Bilsteins are the popular choice on here for OEM replacements. You could get the Bilstein HD's for a direct replacement, or the 5100's for another 1/2" of lift. What are the specs on your truck? (year, 4x2/ 4x4)

2" is the max lift on a 4x4 before you get coil bucket contact, in most cases, so the HD would be your best option.
