Engine Piston Ring for Ford Applications

This engine piston ring is built for Ford Super Duty and Econoline applications that require standard bore sizing and a plasma moly top ring surface. Part number 2M4814 is specified for a 3.551-inch bore and uses a steel top ring with a chrome-treated oil ring for controlled sealing and wear resistance.

Key Features

• Standard oversize configuration for a 3.551-inch bore
• Plasma moly top ring surface for improved ring face durability
• Steel top ring construction for strength under combustion load
• Chrome-treated steel rail and stainless expander oil ring design
• Phosphate-treated second ring with grey iron construction
• Part number 2M4814 for direct catalog identification

Detailed Description

Part number 2M4814 is an engine piston ring set component for Ford E-350 Super Duty, F-250 Super Duty, F-350 Super Duty, F-450 Super Duty, F-550 Super Duty, E-450 Super Duty, Excursion, and related Econoline applications listed in the fitment data. The ring package uses a plasma moly top ring surface, a phosphate-treated second ring, and a chrome-treated oil ring assembly to support cylinder sealing and oil control in standard bore engines. The 90.19 mm bore specification and standard sizing make this a fitment-specific replacement for engines that match the listed dimensions.

This part cross-references Monroe Shocks & Struts (e.g., 2L3Z 6148AA, E917K) for the same application.

What It Is Used For

• Restoring compression loss caused by worn piston rings
• Addressing excessive oil consumption from ring wear
• Correcting blow-by related to poor cylinder sealing
• Replacing rings during an engine rebuild or overhaul
• Matching standard bore engine specifications during service

Installation Notes and Tips

Verify bore size, groove dimensions, and ring end gap before installation. Confirm the engine matches the listed 3.551-inch bore and standard oversize specification, and inspect cylinder walls for taper, scoring, or out-of-round conditions before assembly. Use clean assembly practices and follow the engine builder’s ring installation procedure for proper seating.
