Mahle Rings Cat 3500 Series 3508 Ind Gen Marine 81216 Cyl 6.700 in. Bore Sleeve Assy Ring Set

If you're rebuilding the engine in your Cat 3500 Series 3508 Industrial Generator Marine application, getting the cylinder bore sealed up right is critical. This Mahle OE Piston Ring Set, part number 81216, is designed to fit a 6.700 inch bore, ensuring a tight seal between the piston and cylinder wall. A good seal means better compression, improved oil control, and overall smoother engine operation.

Mahle is a well-known name in engine components, and this ring set is built to meet the demands of industrial and marine use. The rings are made to precise tolerances, which helps them seat properly against the cylinder wall and the piston groove. This attention to detail is important for long-term reliability and performance, especially in applications where the engine runs for extended periods.
