CP Radial Wall Extra Low Tension Flex Vent Oil Ring 4.015 Bore / 2.0mm / .130 For Single Piston

This is a CP Pistons Radial Wall Extra Low Tension Flex Vent Oil Ring. It's designed for a 4.015 inch bore and features a 2.0mm oil ring width with a 0.130 inch height for a single piston application. The flex vent design helps the ring conform to the cylinder wall, ensuring better oil control.

This oil ring is built with a radial wall construction, which contributes to its extra low tension. This characteristic is important for reducing drag and friction within the cylinder, allowing the engine to perform more efficiently. The flex vent feature is key to its performance, allowing the ring to adapt to minor imperfections in the cylinder wall for a more consistent seal and improved oil scraping.
