MAHLE 41940.030 piston ring set for the 2004-2010 Ford E-350 Super Duty V8 6.0L and other vehicles seals the pistons against the cylinder walls. The oil ring also wipes excess oil off the walls.
Worn rings can show up as rising oil consumption, blue-gray exhaust smoke or weak power. Before you replace the rings, rule out other oil sources such as worn valve seals or a leaking gasket, because the smoke and oil loss can start there.
It also fits the 2004-2010 Ford E-450 Super Duty V8 6.0L and the 2003-2007 Ford F-250 Super Duty V8 6.0L. The fitment calls for one set per vehicle. If your vehicle is not among these, look it up in the "Vehicles it fits" section on this page.
