BBC Durathon Roller Lifters - Tall Body

The BBC Durathon Roller Lifters - Tall Body are precision-engineered valve lifters specifically designed for big-block Chevy engines that require increased lift and aggressive cam profiles. These tall-body roller lifters cater to high-performance enthusiasts and engine builders seeking reliable valvetrain geometry for both modern and classic BBC applications.

Constructed with hardened roller wheels, the Durathon roller lifters minimize sliding friction and significantly reduce wear on the camshaft lobe, making them ideal for tight lash settings or solid-roller cam timing. The tall-body design extends the lifter length, which is crucial for accommodating high-lift cams that might interfere with standard lifter bodies. ISKY's engineering ensures consistent oil flow to the roller bearing, enhancing durability and performance.

These lifters are perfect for BBC engine builders looking to upgrade from flat-tappet designs or transition to roller-cam technology without the need to replace the entire engine block. Proper installation requires careful valve-lash setup and verification of lifter preload to achieve optimal performance in high-output street engines and competition applications.
