6.7L Power Stroke Diesel HD Replacement Piston Kit with Rings (2011–2019)

Heavy-Duty Replacement Pistons Built for Work and Performance

Upgrade your 2011–2019 Ford 6.7L Powerstroke with this heavy-duty piston and ring kit designed for reliability in towing, fleet, and high-load applications. This kit fits both 2011–2016 and 2017–2019 model years and delivers the durability you need for long-term engine performance.

Built for Strength and Durability

These pistons feature a steel top ring groove to handle higher cylinder pressure and heat. The included plasma-coated steel top ring and ductile iron second ring improve sealing, reduce blow-by, and hold up under heavy-duty use.

Reduced Friction and Better Wear Protection

Each piston includes a Grafal moly-based skirt coating that reduces friction and helps prevent scuffing. For additional heat protection, you can upgrade to optional ceramic-coated piston tops.

IMPORTANT – Piston Sizing Agreement

Measure cylinders at a qualified machine shop before ordering. Piston size changes after ordering will require restocking and shipping fees. Ceramic-coated or machined pistons are non-returnable.
