Detailed Description

WH655CP is engineered for engine rebuilds that require a standard-size piston with a recessed head profile and controlled compression characteristics. The hypereutectic alloy helps provide stable dimensional performance, while the skirt coating supports reduced friction at the cylinder wall. This piston is listed for 1994-2003 Dodge Ram 1500, 1994-2002 Dodge Ram 2500 and Ram 3500, 1998-2003 Dodge Dakota and Durango, and select Dodge B-Series and Ram van applications. If you are sourcing a Sealed Power WH655CP piston for a Dodge Ram 1500 or Dodge Dakota engine rebuild, verify bore, pin diameter, and clearance requirements before assembly.

This part cross-references Anchor 3222 for the same application.

What This Piston Helps Address

• Restores worn or damaged cylinder sealing surfaces during an engine rebuild
• Addresses compression loss caused by piston wear or scoring
• Supports repair of oil consumption related to worn piston and ring sealing
• Helps correct noise or slap associated with excessive piston clearance
• Provides a replacement for standard-bore Dodge truck and van engine service

Installation Notes and Tips

Confirm cylinder bore, piston-to-wall clearance, and ring groove dimensions before installation. The carton label should be used for minimum clearance guidance, and the piston should be matched to the correct application by year, engine, and bore specification. For Dodge Ram 2500, Ram 3500, Dakota, and Durango rebuilds, verify all machining measurements before final assembly.
