DJ Rock PR326 Engine Piston Ring Set

Engine Piston Ring Set for Geo and Isuzu

DJ Rock PR326 is a premium engine piston ring set built for 80 mm bore applications. It is engineered to maintain cylinder sealing, control oil consumption, and support heat transfer across the piston and cylinder wall in serviceable internal combustion engines.

Key Features

• Premium-grade piston ring set for engine rebuild and repair work
• Top compression ring thickness: 1.2 mm
• Second compression ring thickness: 1.2 mm
• Oil ring thickness: 3 mm
• Bore diameter: 80 mm
• Manufactured from cast iron or steel alloy materials for strength and wear resistance
• Surface treatments may include chrome plating, molybdenum coating, or nitriding for improved sealing and reduced friction

Detailed Description

DJ Rock PR326 is a direct-fit piston ring set for select Geo Storm and Isuzu applications, including the 1990-1993 Geo Storm, 1991-1993 Isuzu Stylus, 1990-1992 Isuzu Impulse, and 1989 Isuzu I-Mark. This part cross-references 013-8211 and E-547KC for the same application. Built to OEM-quality standards, PR326 is specified for complete engine service where consistent compression, oil control, and thermal stability are required. If you are rebuilding a Geo Storm engine or servicing an Isuzu Impulse, this ring set provides the correct 1.2 x 1.2 x 3.0 configuration for the listed 80 mm bore engines.

What It Helps Address

• Low compression caused by worn or fatigued piston rings
• Excessive oil consumption from poor oil control ring sealing
• Blow-by and crankcase pressure from reduced cylinder sealing
• Uneven cylinder performance during engine rebuilds
• Loss of ring tension or sealing efficiency in high-mileage engines

Installation Notes and Tips

Verify bore diameter, ring thickness, and engine code before installation. Clean ring grooves thoroughly, check end gaps to specification, and inspect cylinder wall condition before assembly. PR326 is listed for complete engine service on the confirmed Geo and Isuzu fitments, so match the engine configuration and notes exactly before ordering.

Quality Assurance

DJ Rock PR326 is manufactured to meet or exceed OEM quality standards, with precision-engineered materials and surface finishes selected for sealing performance and durability in engine service.
