Description

The Darton Sleeves 300-020 is a centrifugally cast nodular iron sleeve designed for high-performance applications. Its unique casting process creates a tough bore finish that promotes quick and complete piston ring seal. Darton pioneered modular sleeve designs and ductile iron material starting in 1978.

These sleeves are built for the demands of racing, offering cast iron performance within an aluminum block. They feature a 130,000-psi tensile strength and are engineered for superior cylinder sealing and ring wear, improving overall block strength and cooling.
