BBC HE Roller Rocker Arm 1.7 Ratio 7/16 Stud Alm

The BBC HE Roller Rocker Arm with 1.7 ratio and 7/16 stud aluminum construction is designed for serious big-block Chevrolet performance builds where valvetrain reliability and precise valve actuation are crucial. These roller rocker arms are essential upgrades for high-revving stroker engines and forced-induction applications, delivering superior mechanical advantage and reduced friction compared to stock stamped steel rockers.

The 1.7 ratio geometry allows for increased valve lift relative to camshaft lobe movement, enabling deeper breathing and faster valve events without excessively increasing valve spring pressure. Roller bearing construction eliminates sliding friction on the cam lobe, reducing heat generation and wear while enabling sustained high-RPM operation that would destroy conventional rocker arms. The lightweight aluminum construction minimizes reciprocating mass and inertial loads on the valvetrain.

These roller rocker arms are ideal for big-block Chevrolet platforms, providing the valvetrain control needed to maximize cam profile efficiency and horsepower output across the RPM range. Whether you're building a street cruiser, weekend warrior, or competition engine, this component is engineered to meet the demands of high-performance applications.
