Engine & Performance Warehouse PR777 Piston Ring Set

The Engine & Performance Warehouse PR777 is a Piston Ring Set Ford Oversize for engine rebuilds. A piston ring set seals the gap between the piston and the cylinder wall. It helps hold combustion pressure, controls the oil on the cylinder wall, and moves heat from the piston to the cylinder wall.

Key Points:

• Piston ring set for Ford engine applications
• Oversize design, intended for use with oversize pistons in a rebuilt or bored engine
• Helps restore compression and oil control during an engine rebuild

Check the ring size against your piston and cylinder bore measurements before installation.
