MAHLE CLEVITE Engine Piston Ring Set Part No: S41685

$47.25

The Mahle Clevite S41685 piston ring set is engineered for heavy-duty diesel overhauls where cylinder sealing and oil control are critical. Designed for 4.500-inch bore Caterpillar sleeve assemblies, these rings help return worn cylinders to spec by stabilizing compression and minimizing blow-by under load. MAHLE/Clevite ring metallurgy and face design support quick seating, smooth piston travel, and long wear life. Ideal for in-frame or full rebuilds of compatible CAT engines. Available from Wofford Truck Parts.

Specifications

For reliable diesel rebuilding, the Mahle Clevite S41685 Engine Piston Ring Set delivers OE-equivalent sealing for Caterpillar sleeve assembly applications. Piston rings must maintain a tight combustion seal while scraping excess oil from the cylinder wall; S41685 is specified for 4.500" bore CAT diesel platforms, supporting consistent pressure sealing and stable oil control through heat cycling and heavy loads. MAHLE/Clevite manufacturing emphasizes precise ring geometry, durable materials, and finishes that promote fast break-in with extended service life. Use S41685 to restore power, reduce oil consumption, and improve overall engine efficiency. Sold by Wofford Truck Parts.
