Detailed Description

Part Number 144 is an engine piston ring set component intended for vintage inline-six cylinder blocks with a 3.25-inch bore and standard groove dimensions. The ring package uses grey iron for the compression rings, phosphate treatment on the top and second rings, and a chrome rail oil ring surface treatment to support ring seating and cylinder wall contact. This configuration is appropriate for restoration work where original-style dimensions and materials matter. It is listed across many classic Dodge and Plymouth applications, including Dodge Coronet, Plymouth Suburban, and Fargo pickup and panel delivery models. Part Number 144 is also cross-referenced to Monroe Shocks & Struts 37NP and 134P for the same application.
