All three rings for MAHLE/CLEVITE uses on their aftermarket loaded pistons are truly unique and are without a doubt, these ring-sets the absolute best in the business. The top rings are high strength steel with high velocity Moly impregnation. They are an ideal mix of metals because the steel provides superior durability while the Moly facing provides a hard surface that allows superior compression sealing. 4. The second ring (middle of piston) is your second line of defense for sealing compression from the above & oil from below the piston. The high strength steel composition of this ring is ideally suited for both of these critical purposes. 5. The oil ring (bottom ring) is completely unique for MAHLE CLEVITE. These rings have been improved further by adding a nitrite coating & a chrome finish.
