Description
Proper ring seal is foundational to engine reliability and performance—inadequate compression leads to blow-by, oil consumption, and lost horsepower. The Hastings CM5532040 piston ring set delivers consistent ring tension and plasma moly coating to maintain bore contact across the rpm range, whether you’re rebuilding a naturally aspirated engine or preparing for sustained racing duty. This is a direct replacement for 4.040″ bore applications, ensuring OEM-quality performance without the premium price.
