Detailed Description

DJ Rock PR162 is an engine piston ring set engineered for Mitsubishi Eclipse, Galant, Lancer, and Outlander engines that require an 87 mm bore and 1.2x1.2x2.0 ring sizing. The ring package is designed to restore cylinder sealing performance, regulate oil consumption, and maintain combustion pressure across the engine. PR162 is manufactured to meet or exceed OEM quality standards and uses materials selected for strength, thermal stability, and long service life.

For buyers searching for a Mitsubishi Eclipse piston ring set, Mitsubishi Galant piston ring set, or Mitsubishi Lancer piston ring set, PR162 provides the correct dimensional profile for the listed applications. The part number PR162 also helps confirm the correct replacement when matching engine rebuild specifications.

What It Helps Address

• Low compression caused by worn piston rings
• Excessive oil consumption from ring wear or poor sealing
• Blow-by from reduced cylinder wall sealing
• Uneven cylinder performance during engine rebuilds
• Loss of heat transfer from piston to cylinder wall

Installation Notes and Tips

Verify bore diameter, ring thickness, and engine code before installation. Clean the ring grooves and cylinder walls thoroughly, and confirm end gaps against the engine builder’s specifications. Proper ring orientation and careful handling during assembly help preserve sealing performance after installation.

Quality Assurance

DJ Rock positions this piston ring set as a premium replacement built to OEM-level dimensional and material standards. The PR162 is manufactured with wear-resistant alloys and surface treatments that support consistent sealing performance in Mitsubishi engine rebuild applications.
