Engine & Performance Warehouse PR474 Piston Ring Set

The Engine & Performance Warehouse PR474 is a Piston Ring Set Ford Oversize for engine rebuilds. Piston rings sit around the pistons and seal the gap between the piston and the cylinder wall. The seal helps hold combustion pressure in the cylinder.

What a piston ring set does:

• Seals the piston to the cylinder wall to help maintain compression
• Helps control the oil film on the cylinder wall
• Helps carry heat from the piston to the cylinder wall

This is an oversize set, so it is meant for engines with oversize pistons and bores. Match the ring size to your piston and bore size before you install it.
