Product Details
This Mahle ring set includes file-fit piston rings, specifically sized at +.005 inches over standard bore. You get rings measuring .043 inches for the top and second compression rings, and a 3.0mm oil ring. These are made from steel and feature standard tension, designed for builders who need to precisely set the ring gap for their specific engine build. File-fit rings are a popular choice when rebuilding engines where exact tolerances are critical for performance and sealing.
Mahle is a well-known name in engine components, and this set reflects their focus on precision. The steel construction offers good durability for a wide range of applications. Because these are file-fit, they allow you to achieve the perfect ring-to-wall clearance, which is essential for proper oil control and compression sealing, especially in performance or heavily modified engines. This attention to detail in the ring gap can make a notable difference in engine longevity and performance.
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 recommended ring gap specifications and installation procedures.
