ModMax 4.6 5.4 Plasma Moly File-Fit Rings 1.5/1.5/3MM

ModMax Plasma Moly Piston Rings are a necessity for high cylinder pressures and performance Modular engines. These rings are manufactured with exacting tolerances for OEM sized 1.5mm top groove, 1.5mm 2nd groove, and 3mm oil groove pistons. Our unique and exclusive design allows these rings to work on all Modular pistons with OEM sized ring grooves (ModMax, CP, Ross, Mahle, KB, Probe, Diamond, Manley...etc.) The rings feature a PLASMA MOLY faced high strength ductile iron top ring engineered for instant seating, superior sealing, and optimum durability. The second cast iron rings feature a tapered face for cylinder scraping reducing oil migration into the combustion chamber. Oil rings are a low drag, yet standard tension design for superior oil control for use in all naturally aspirated or boosted environments. The rings come in standard, +.020", or +.030" bore sizes with an additional .005" oversize for file fitting. NOTE: These rings MUST be file fit for each particular engine.
