What is included with this piston set?

This Mahle OE piston set includes eight pistons, eight sets of matched piston rings, eight wrist pins, and eight sets of retaining clips. Everything needed to install the pistons is included.

Are these pistons ready to install right out of the box?

Yes, these pistons come with the piston rings mounted, along with the wrist pins and clips. This makes them ready for installation by the engine builder, saving time and ensuring all components are matched.

What is the benefit of the expansion-controlled design?

The expansion-controlled design allows the pistons to maintain small, precise clearances within the cylinder bore as the engine heats up. This helps reduce engine noise, minimize wear, and improve oil control for better overall engine performance and longevity.

Product Details

When you're rebuilding the heart of your Ford truck with the 7.3L 445 diesel engine, you want parts that are built to the original specifications. This piston set from Mahle OE gives you exactly that. You'll receive eight pistons, each complete with matched piston rings, wrist pins, and retaining clips, all ready to go right into your engine build. Mahle is a major OE supplier, meaning these pistons are made to the same standards and feature the same technologies as the ones that originally came in your truck.

These pistons are designed with compensated ring grooves, which helps ensure the rings load properly and maintain good oil control. They also feature an expansion-controlled design. This means they're built to maintain tight, small clearances within the cylinder bore even as the engine heats up. This advanced design helps reduce engine noise, minimize wear over time, and keep emissions in check, all while improving how well the engine manages its oil. This attention to detail is what you'd expect from a leading OE manufacturer like Mahle.

This set is a solid choice for a wide range of Ford trucks from 1988 to 1994, including models like the F-250, F-350, and E-350 Econoline vans. Having the rings, pins, and clips included saves you time and ensures you have the correct components for a proper installation. Just be aware that these are not CARB approved and cannot be shipped to California.
