BBTV 2D7276 Engine Piston Ring

Engine piston ring set overview

This engine piston ring set, part number 2D7276, is built for 4.016-inch bore applications with standard sizing. It uses a ceramic chrome top ring, a phosphate-treated second ring, and grey iron and ductile iron materials for the ring package.

Key features

• Standard-size piston ring set for 4.016-inch bore engines
• Ceramic chrome top ring surface treatment for wear resistance
• Phosphate-treated second ring for added surface protection
• Grey iron and ductile iron construction for the ring package
• Fits 6-cylinder engine applications listed for Ram, Freightliner, International, Crane Carrier, and El Dorado platforms

Detailed fitment and application

Part number 2D7276 is listed for 2004-2009 Dodge Ram 2500 and Ram 3500 applications, plus 2005 Freightliner XB Line, 2007 International 8600 SBA, 2004 Crane Carrier Low Entry, and 2004 El Dorado Escort RE. The fitment data also identifies standard-size ring dimensions and a 6-cylinder application profile, making this a direct match for the specified engine configurations.

What this part helps address

• Excessive oil control loss from worn ring surfaces
• Compression loss caused by ring wear or fatigue
• Oil consumption related to ring sealing issues
• Reduced cylinder sealing performance in high-mileage engines

Installation notes and tips

Verify bore size, groove dimensions, and cylinder count before installation. Confirm the listed 4.016-inch bore and standard-size specification against the engine being serviced, and inspect the piston grooves for wear or damage before assembly. Part number 2D7276 should be matched to the exact engine application shown in the fitment data.
