Unlock big-air performance and streetable spool with the INDUSTRIAL INJECTION 3662307111 SUPER PHATSHAFT 66. Built around a robust journal-bearing center section and a 360° thrust upgrade, the Super PhatShaft 66 is a proven drop-in T3 upgrade for 1994–2002 Dodge Ram 2500/3500 5.9L Cummins (12-valve 1994–1998, 24-valve 1998.5–2002).
Why It Rocks
- Big 66mm compressor for strong mid–top-end power while retaining practical drivability.
- Heavy-duty 360° thrust for durability under increased boost and aggressive fueling.
