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

The COMP Cams BBC Ultra Gold R/A rocker arm with 1.7 ratio and 7/16 stud mount is a high-performance component engineered for big block Chevy engines requiring precise valve actuation and durability under sustained high-RPM operation. This full roller rocker arm delivers the mechanical advantage needed to optimize camshaft lift while maintaining reliable contact with the valve stem across the entire lift cycle. The 1.70:1 ratio provides a balanced compromise between valve lift multiplication and valve train speed, making it suitable for street performance and moderate competition builds where consistent valve timing is critical.

Constructed from aluminum and finished in gold anodize, this rocker arm combines low rotational mass with corrosion resistance. The full roller design minimizes friction at the pushrod interface, reducing parasitic power losses and heat generation during extended operation. The 7/16-inch stud mount directly attaches to standard big block Chevy cylinder head specifications, ensuring straightforward installation without custom fabrication. COMP Cams' Ultra Gold series rocker arms are precision-manufactured to tight tolerances, ensuring consistent performance across the entire valve train and supporting reliable engine operation in high-demand applications.

This rocker arm is designed for engine builders and performance enthusiasts constructing or upgrading big block Chevy powerplants for street rods, muscle cars, marine engines, and off-road applications. The 1.7 ratio suits naturally aspirated and moderately boosted engines where valve timing precision matters more than extreme lift multiplication. Each unit ships individually, allowing builders to purchase complete rocker arm sets according to their specific valve train configuration and performance requirements.

COMP Cams remains the industry standard for valve train components, with decades of proven reliability across professional racing, OEM restoration, and street performance segments. The Ultra Gold series represents mid-range performance engineering—offering genuine mechanical advantages without the extreme cost of full race-spec components, making it a practical choice for builders prioritizing durability and consistent performance over competition-only specifications.
