Sealed Power 2790PN Engine Piston

Engine piston overview

Sealed Power 2790PN is a premium engine piston built for heavy-duty diesel applications that require precise ring groove dimensions and a cast aluminum construction. It is listed for Ram 2500 and Ram 3500 applications across multiple model years, with fitment details that include standard configuration notes on several rows.

• Premium-grade engine piston for demanding cylinder block service.
• Cast aluminum construction for a balance of strength and thermal performance.
• Bowl-style piston head design.
• Ring groove widths listed at 3.0 mm, 2.5 mm, and 3.50 mm.
• Oversized: No.

Detailed product information

The Sealed Power 2790PN piston is engineered around a 107.00 mm cylinder bore diameter, a 69.36 compression height, and a 40.00 mm piston pin outside diameter. Its bowl head profile and premium grade type make it a direct-fit engine piston choice for Ram 2500 and Ram 3500 diesel engine rebuild work where dimensional accuracy matters. This part number, 2790PN, also cross-references Monroe Shocks & Struts (e.g., 2243732, 4376347) for the same application.

Sealed Power focuses on modern engine requirements with advanced materials and ISO- and QS-certified manufacturing processes. For buyers searching for a Ram 2500 engine piston or Ram 3500 piston replacement, 2790PN provides the core specifications needed to match the original engine design.

Used for engine repair

• Replacing a worn or damaged piston during engine overhaul.
• Restoring compression control when piston wear affects sealing.
• Addressing ring groove wear or dimensional mismatch in rebuilds.
• Supporting diesel engine service on Ram 2500 and Ram 3500 platforms.

Installation notes and quality

Verify cylinder bore diameter, compression height, piston pin diameter, and ring groove widths before installation. Confirm the application against the engine build specifications for the exact Ram 2500 or Ram 3500 model year being serviced. Assembly lubricant is not included.

Sealed Power parts are manufactured under ISO and QS certified processes and use current material and design practices to meet modern engine demands.
