Shaft Rocker Arm Kit BBC 1.7/1.7 Ratio

Jesel Sportsman Series rocker systems replace inadequate stud rocker assemblies, handling aggressive springs and cam profiles. These 2024 aluminum shaft rockers withstand open spring pressures up to 900 lbs while maintaining precise valve lash settings. They are engineered for reliable service in various applications, from daily drivers to bracket drag cars, marine, and oval track racing. Jesel Sportsman Series rocker kits bolt on without cylinder head modifications and often fit under stock valve covers. Rocker geometry is preset and engineered using the common valve supplied with the cylinder head for bolt-on installation.
