BBTV 2C4984 Engine Piston Ring

Engine Piston Ring for Saturn 1.9L Applications

This engine piston ring set is built for Saturn 1.9L four-cylinder applications and is identified by part number 2C4984. It is a standard-size replacement with chrome-treated top ring surfaces and a steel rail oil ring design for controlled sealing and oil management.

Key Features

• Standard bore size: 82.00 mm / 3.228 in.
• Chrome top ring surface treatment for improved wear resistance.
• Steel top ring construction with a phosphate-treated second ring.
• Steel rail and stainless expander oil ring design.
• Configured for four-cylinder engine applications.

Detailed Description

Part number 2C4984 is an engine piston ring set for Saturn SL, SL1, SL2, SW1, and SW2 models with the 1.9L engine family. The ring package uses a chrome-treated top ring, a grey iron second ring, and a steel top ring to support cylinder sealing and oil control in standard-bore engines. The 82.00 mm bore specification and standard oversize designation make it a direct service option for engines that retain factory bore dimensions.

This part cross-references Monroe Shocks & Struts (e.g., E976K) for the same application.

What It Is Used For

• Restoring compression loss caused by worn piston rings.
• Reducing oil consumption linked to ring wear or poor sealing.
• Addressing blow-by from tired cylinder sealing surfaces.
• Replacing rings during a standard engine rebuild.

Installation Notes and Tips

Verify bore size, ring end gap, and groove dimensions before installation. Match the ring set to the engine’s cylinder count and confirm the bore remains at standard size. Clean ring grooves thoroughly and follow the engine builder’s installation procedure for proper seating.

Quality Assurance

Use this part as a standard replacement for the listed Saturn applications. Confirm fitment by year, model, and engine specification before ordering. Part number 2C4984 should be matched to the engine’s bore and ring groove requirements for correct service.
