Pistons and rings seal the fuel in the cylinder,compress it, and then receive the energy from the firing explosion. It’s important to have appropriate clearances as well as high quality pistons and rings to insure a perfect seal.
Standard OEM and third party pistons ensure your engine runs smoothly. Because of the wear on pistons, they need to be replaced when rebuilding your engine.
High Performance Pistons
High performance pistons are available for many engines, enabling higher compression ratios, larger displacements, and less weight.
They are also composed of higher quality material, which makes them stronger and able to withstand the more demanding conditions of a high performance engine.
