SPI .020 Over Bore Piston Rings for Polaris

This set of two SPI .020 over bore piston rings is designed for Polaris 340 snowmobile engines from 1994 to 2008, with a bore size of 62.8mm, providing replacement rings for engine rebuilding.

Overview

The SPI .020 over bore piston rings are intended for Polaris 340cc two-stroke snowmobile engines manufactured between 1994 and 2008. They offer a .020-inch oversize to match a cylinder that has been bored to 62.8mm. This aftermarket set includes two complete ring sets (each consisting of multiple rings per piston), suitable for owners and mechanics rebuilding these engines.

Built For Performance

• Made from high-strength ductile iron for wear resistance
• Precision-ground to achieve the correct ring gap for .020 over bore
• Includes two sets for two pistons (or one set per piston if using one piston, but title says 2 sets)
• Provides proper compression sealing and oil control
• Compatible with standard Polaris 340 cylinder dimensions

Fits These Machines

• for Polaris 340 Snow (1994-2008)

On-The-Job Use

• Commonly used during top-end rebuilds on Polaris 340 snowmobile engines
• Ideal for restoring compression in engines that have been bored oversize
• Used in conjunction with oversize pistons for a complete cylinder kit

Specs At A Glance

Good To Know

Q: Are these rings for the top compression ring and oil ring? A: Each set typically includes a top compression ring, a second compression ring, and an oil ring assembly; verify the kit contents.

Q: Do I need to purchase separate piston rings for each cylinder? A: The package contains two sets, which is sufficient for a two-cylinder engine or for two single-cylinder engines.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
