Key Features

• Premium-grade piston ring set for internal engine rebuild and service work.
• Designed with top compression, second compression, and oil control ring functions.
• Manufactured from cast iron or steel alloys for strength and wear resistance.
• Surface treatments such as chrome plating, molybdenum coating, or nitriding help reduce friction and improve sealing.
• Fits applications with a 101.6 mm bore diameter and 1.5 x 1.5 x 4.0 ring thickness configuration.
• Part number PR1141 for catalog and fitment verification.

Detailed Description

The DJ Rock PR1141 piston ring set is engineered for engines that need consistent compression retention and oil control during rebuild or overhaul service. It is a direct engine-service component for a wide range of Ford, Dodge, Jeep, Lincoln, and Mercury applications, including Ford F-150, Ford Mustang, and Dodge Ram 1500 platforms listed in the fitment data. The ring package is specified around a 101.6 bore diameter and a 1.5 x 1.5 x 4.0 configuration, making PR1141 a fitment-specific choice for matching engine builds.

DNJ engine piston ring sets are manufactured to meet or exceed OEM quality standards and use materials selected for thermal stability and wear resistance. PR1141 is intended for complete engine service where sealing, oil regulation, and heat transfer are critical to restoring proper engine operation. This part cross-references Hastings Piston Rings (e.g., 2M4726) and Sealed Power (e.g., E-908K) for the same application.

What It Is Used For

• Restoring cylinder compression after engine wear.
• Reducing oil consumption caused by worn rings.
• Improving combustion sealing in rebuilt engines.
• Supporting heat transfer from the piston to the cylinder wall.
• Addressing blow-by and related loss of engine efficiency.

Installation Notes and Tips

Verify bore diameter, ring thickness, and engine application before installation. PR1141 is listed for complete engine service, so confirm the engine build matches the fitment notes for your Ford, Dodge, Jeep, Lincoln, or Mercury application. Clean ring grooves and cylinder walls thoroughly, and follow standard ring end-gap and break-in procedures during assembly.

Quality Assurance

DJ Rock lists this piston ring set as premium grade, and the manufacturer states that DNJ engine components are made to meet or exceed OEM quality standards.
