Multiquip 2672350307 Piston Ring Set 0.50 O.S.

The Multiquip 2672350307 Piston Ring Set 0.50 O.S. is a genuine OEM component designed for GA-6RE and GA-6REA portable generators. As a factory-authorized replacement, this oversize ring set is engineered to restore proper cylinder sealing in engines that have been bored or honed to the 0.50mm oversize specification. Confirm your engine bore size before ordering to ensure this set is the correct fitment for your machine.

Key Features

• Genuine OEM Ring Material and Tolerancing — Manufactured to Multiquip's exact metallurgical and dimensional specifications, ensuring correct ring tension, gap clearance, and sealing surface contact for this engine family.
• 0.50mm Oversize Specification — Designed specifically for cylinders bored or honed to the 0.50 O.S. dimension; installs directly into a properly prepared bore without additional machining.
• Confirmed Fitment for GA-6RE and GA-6REA — Verified compatible with GA-6RE and GA-6REA portable generator models, making part selection straightforward during engine rebuild.
• Restores Compression and Oil Control — Worn or broken piston rings allow combustion gases to bypass the piston and oil to enter the combustion chamber; a correctly fitted ring set restores compression pressure and prevents oil consumption.
• Complete Set for Full Ring Replacement — Includes the full piston ring set so compression, scraper, and oil control rings are replaced together, supporting a thorough and balanced engine overhaul.

Piston rings form a dynamic seal between the piston and the cylinder wall, serving two critical roles: maintaining combustion chamber pressure so the engine produces full power, and controlling oil so it lubricates the cylinder without burning in the combustion process. Over time, rings wear, lose tension, or break — symptoms include loss of power, excessive oil consumption, blue exhaust smoke, and hard starting. Replacing the ring set as part of an engine rebuild restores these seals and brings engine performance back to specification.
