I went with a set of Seat Risers from Rough Country.
They can be found here: Jeep Accessories - Seat Risers
So far I dont have any complaints with them. The only thing i would do differently is get some better washers and maybe some grade 8 hardware just for peace of mind. The washers that came with the kit were kinda cheap and deformed a little while tightening down due to the holes in the seat frame.
