Logitech Shifter w/ Sequential Shifter Mod. This thing works really well and the mod kit is high quality. Only selling because I finally upgraded. Will work with any Logitech Wheel Base or as a standalone with the racing adapter.

The Logitech Racing Shifter with Sequential Mod is a video game accessory designed for use with racing games. It is a shifter that allows for more realistic gear shifting during gameplay. The shifter has a sequential mode for quick shifting and is made by the popular brand Logitech.
