Fitment Notes

• This is a 0.030 in. / 0.75 mm oversize piston set - cylinders must be bored and honed to 0.030" over stock before installation
• Prices are shown per piston - must be ordered in a quantity of 8 for a complete engine set
• Features standard compression height - not a reduced-compression variant; see 224-3409WR.030 for reduced compression option
• Does not fit 6.0L, 6.4L, or 6.7L Power Stroke engines

Features

• OE-quality cast aluminum pistons built to original equipment specifications for the 7.3L Power Stroke T444E direct injection diesel
• Reentrant bowl (Ricardo Bowl) crown design engineered specifically for the T444E's direct injection combustion system
• Compensated ring grooves ensure consistent ring loading and long-term oil control across all operating conditions
• Expansion-controlled design maintains tight piston-to-wall clearances, reducing noise, wear, and oil consumption
• Keystone top ring groove resists ring sticking under the extreme cylinder pressures of a turbocharged diesel
• GCL-40URW ring pack included - pre-matched to piston for correct gap, tension, and sealing performance
• Pin offset design minimizes piston slap and reduces startup noise under cold or light-load conditions

Product Description

The MAHLE 224-3163WR.030 is a complete piston and ring set engineered for 1994-2003 Ford 7.3L Power Stroke and Navistar T444E diesel engines requiring a 0.030 in. overbore. Each piston is built to OE specifications with the correct reentrant bowl crown geometry for the T444E's direct injection system, ensuring proper air-fuel mixing and combustion efficiency. The matched GCL-40URW ring pack is included and pre-sized for the 4.140 in. bore, eliminating the guesswork of sourcing rings separately and ensuring proper seal from the first startup.

This set is ideal for engine rebuilds where cylinder walls have been machined to 0.030" over stock. Professional block preparation - boring and honing to the correct oversize - is required prior to installation. With standard compression height and non-coated skirts, these pistons restore factory power output and reliability to any 7.3L Powerstroke build, whether for daily hauling, towing, or heavy-duty commercial use.
