The ring package combines a carbon steel top ring, carbon steel second ring, and stainless steel oil ring assembly, with a plasma-moly coated ring face to support low-friction operation and consistent cylinder sealing. This configuration is relevant for rebuild work where ring material, thickness, and groove style must match the piston and bore specification. The Mahle 42149CP.020 is listed for 2011-2017 Ford F-150, Ford Lobo, Ford Mustang, and 2011-2014 Lincoln Mark LT applications.\u003c\/p\u003e\u003cp\u003eThis part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eExcessive oil consumption from worn ring sealing surfaces.\u003c\/li\u003e\n\u003cli\u003eLoss of compression caused by ring wear or cylinder sealing issues.\u003c\/li\u003e\n\u003cli\u003eIncreased friction from degraded ring face material.\u003c\/li\u003e\n\u003cli\u003eRebuild needs for engines requiring 0.020 in oversize rings.\u003c\/li\u003e\n\u003cli\u003eFitment-specific replacement during engine overhaul work.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify bore diameter, oversize requirement, ring thickness, and shallow groove specification before installation.
