Pro Tie-Bar Roller Lifter BBC .904 Dia

The JESEL Pro Tie-Bar Roller Lifter BBC .904 Dia is a high-performance component designed for serious big-block Chevrolet engine builders and performance mechanics. This roller lifter assembly is specifically engineered for high-RPM applications, ensuring reliable valve train geometry even under aggressive cam profiles. It is an essential upgrade for those looking to enhance their BBC engine's performance.

This lifter features a .904-inch diameter roller element that maintains precise contact with the camshaft lobe, while the innovative tie-bar design prevents lifter separation. This is particularly crucial for engines running radical valve timing events or high-lift profiles. The roller bearing design significantly reduces friction and wear compared to traditional flat-tappet lifters, allowing for smoother valve acceleration and more consistent valve operation across the RPM range.

Engine builders engaged in high-performance street applications, circle track racing, and drag racing rely on JESEL lifters for their proven reliability at sustained high RPM. By minimizing side loading on the lifter bore, this precision construction extends the service life of both the lifter and camshaft, making it a worthwhile investment for any serious engine builder.
