Description

Rebuild your engine's compression from the bore up with the MAHLE Engine Piston S224-3891-0.75MM. This piston drops in as a replacement for the 2008-2010 Ford F-250 Super Duty, 2008-2010 Ford F-350 Super Duty, 2008-2010 Ford F-450 Super Duty and 2008-2010 Ford F-550 Super Duty, restoring a fresh sealing surface for a cylinder that has been reconditioned during an engine overhaul.

Core job: the piston seals the combustion chamber and transfers combustion force through the wrist pin to the connecting rod and crankshaft.
Oversize designation: the part number denotes a 0.75mm oversize, so it is intended for a cylinder that has been bored and honed to the matching oversize dimension.
Ring-pack carrier: houses the piston rings and rides against the cylinder wall to help maintain compression and control oil.

Piston scoring, scuffed skirts, cracked ring lands, or excessive blow-by are signs the original may need replacing; diagnose the underlying cause before installing.

Interchange: 8C3Z 6108-DB · 8C3Z6108DB
