Detailed description

Part number 660 is an engine piston ring set for standard-bore V8 rebuilds. The ring package uses grey iron for the top and second rings, with phosphate surface treatment to support break-in and wear control, while the oil control ring uses a steel rail and stainless expander with chrome treatment. This combination is suited to engine rebuilds where cylinder sealing, oil control, and ring stability are priorities. It is listed for a broad range of Chevrolet, Pontiac, and GMC passenger cars and trucks, including Chevrolet Camaro, Chevrolet Chevelle, Pontiac Firebird, and GMC pickup applications.

This part cross-references Monroe Shocks & Struts (e.g., 222P, 235P) for the same application.
