2003-2004 Power Stroke 6.0L X-Series Pistons (346106)

Fits:

Industrial Injection X-Series Premium Piston Kits upgrade your 2003-2004 Power Stroke 6.0L with diesel pistons engineered for durability, reliability, and high-performance power. Each kit is a true drop-in replacement balanced matched set, complete with rings, wrist pins, and clips, and is available in Standard, .020", and .040" oversized options.

Built as an OEM-style replacement, the Stock kit delivers improved reliability and performance over standard replacement pistons for dependable rebuilds.

Every kit features a ceramic piston skirt coating that reduces friction, handles loads exceeding 350,000 PSI, and lubricates at temperatures over 1600°F with no piston clearance changes, plus a premium PVD ring pack (certain applications) for harder, smoother ring sealing and longer durability than traditional nitride rings.
