Mahle OE Ford Trk 445 7.3L Diesel Eng 1989-94 Piston Set (Set of 8)

If you're rebuilding the engine in your 1988-1994 Ford truck with the 7.3L diesel, a solid set of pistons is crucial for getting that power plant back to life. Mahle OE pistons are built to the same standards as the original equipment, meaning they'll fit right and perform as expected. They come ready to install, with the piston rings already mounted, and include the necessary pins and clips, saving you a step during assembly.

These pistons feature compensated ring grooves, which help ensure the rings seat properly and maintain good oil control. They also use an expansion-controlled design. This means the pistons are made to have tight, but not binding, clearances when the engine reaches operating temperature. This helps reduce engine noise, wear, and emissions, while also improving overall oil management. Mahle is a well-known name in OE piston manufacturing, so you can be confident in the quality and reliability of these components for your diesel rebuild.

This set includes eight pistons, enough for a complete engine overhaul. Since these are OE-quality replacements, they are designed to be a direct fit for a wide range of Ford E-Series and F-Series trucks from 1988 through 1994 equipped with the 7.3L diesel engine. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
