Choosing the Right Piston Option
Stock Replacement pistons are a strong choice for standard rebuilds, tow rigs, and reliable engine setups. Coated & Chamfered pistons add piston top coating, skirt coating, chamfered piston tops, and reduced compression height for more demanding Cummins builds. Fly Cut, Coated & Chamfered pistons add .100" valve reliefs for builds that require additional piston-to-valve clearance.
