Engine Piston
The Mahle Clevite 2243374X piston crown is designed for CAT 3406E piston assemblies where the crown is serviced separately from the skirt. Manufactured to OE combustion-bowl geometry for 137 mm (5.400") bores and an 18.0:1 compression setup, it helps maintain proper heat control, sealing, and power balance under high-load duty cycles. This crown-only service part is ideal for targeted repairs during inframe or full overhauls. Supplied new by Wofford Truck Parts.

Specifications
Mahle Clevite 2243374X is a heavy-duty piston crown-only replacement engineered for Caterpillar 3406E diesel platforms. The piston crown forms the combustion bowl and takes the brunt of heat and pressure, so correct OE geometry is critical for proper mixing, compression, and exhaust temperature control. This part is built for 137 mm (5.400") bores and 18.0:1 compression applications, matching the original Cat design for reliable rebuild performance. Replacing a damaged or worn crown helps restore combustion efficiency without requiring a full piston assembly. Available through Wofford Truck Parts for dependable OE-style service.
