CP Ring Set ONLY for 3.090mm Bore Pistons

If you're rebuilding an engine and need to ensure a solid seal between your pistons and cylinder walls, a good set of piston rings is critical. These rings from CP Pistons are made specifically for pistons with a 3.090mm bore size. Getting the right ring for your piston bore is key to proper compression and oil control.

CP Pistons is a well-known name in performance engine building, and these rings are built to match that reputation. They are designed to fit precisely into the grooves of your 3.090mm bore pistons, which helps maintain consistent cylinder pressure and prevents oil from entering the combustion chamber. This attention to detail in sizing is what you'd expect when working on a performance or high-performance engine build where every component matters.

Remember that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for installation procedures and any other components you might need for your rebuild.
