Mahle MS 4.000in1/16in 1/16in 3/16in Drop In Rings

This is a Mahle MS piston ring set, designed for a universal fit across many engine builds. These are standard tension rings with a common size configuration: 1/16 inch for the top and second rings, and 3/16 inch for the oil control ring. They are a drop-in style, meaning they are intended to fit directly onto the pistons without requiring special tools or modifications beyond standard piston ring installation procedures.

Mahle is a well-known name in engine components, and this set uses a standard tension design that works well in a wide variety of applications. The specific sizing is very popular for many classic and modern engine rebuilds, making them a solid option when you need reliable piston rings. They are built to seal the combustion chamber effectively and manage oil consumption.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for correct installation procedures and any other required components for your rebuild.
