BBC Ultra Gold R/A's - 1.7 Ratio 7/16 Stud

The BBC Ultra Gold R/A's - 1.7 Ratio 7/16 Stud rocker arms from COMP Cams are engineered for big-block Chevrolet engine builders and performance enthusiasts seeking reliable valve actuation in high-revving applications. These roller rocker arms are designed for both street and strip use, providing the mechanical advantage and durability needed for various cam profiles.

Featuring a 1.7 ratio configuration, these rocker arms multiply camshaft lift by 1.7 times, enhancing valve lift at the cylinder head. The precision roller design reduces friction and wear compared to traditional stamped steel rockers, improving valvetrain efficiency and extending component lifespan during sustained high-RPM operation. The 7/16-inch stud design ensures compatibility with standard BBC stud girdles and cylinder heads.

These rocker arms are ideal for classic muscle car engines and dedicated racing powerplants, particularly when paired with aggressive hydraulic roller or solid roller camshafts. Their roller bearing construction minimizes parasitic drag losses, providing superior durability, especially in forced-induction or nitrous oxide applications.
