BBM R/A & Shaft Kit - 1.6 Ratio w/EDE Heads

The Sharp Rockers BBM R/A & Shaft Kit with 1.6 Ratio and EDE Heads is a heavy-duty rocker arm assembly engineered for Mopar B and RB-series engine platforms. This shaft-mounted system delivers the mechanical advantage and reliability required for high-performance engine builds, street applications, and competition-level machining where precise valve train control is essential. The 1.6 ratio geometry provides the leverage needed to optimize valve opening characteristics while maintaining consistent actuation across the entire valve lift curve.

Built with roller-tip construction, this rocker arm kit minimizes friction at the pushrod interface and reduces wear on both the rocker and valve stem. The aluminum body with orange anodized finish resists corrosion and heat stress while maintaining lightweight design—critical for reducing parasitic losses in high-RPM applications. The EDE cylinder head compatibility ensures seamless integration with Edelbrock Victor heads, eliminating fitment guesswork. Shaft-mount design provides superior stability compared to stud-mount systems, particularly under aggressive cam profiles and extended valve train stress. The 14.25 lb kit weight reflects the substantial construction necessary for durability in demanding engine environments.

This assembly is purpose-built for Mopar B/RB-series engine platforms—the standard choice for classic muscle car restorations, street machine builds, and vintage drag racing. Buyers rebuilding factory engines or upgrading to performance-level cylinder head packages rely on verified component matching to avoid valve train instability. The combination of the 1.6 ratio and Edelbrock Victor compatibility positions this kit as an integral part of comprehensive top-end combinations where rocker arm geometry directly influences valve timing and flow characteristics.

Shaft-mounted rocker systems represent a higher-durability standard in the Mopar aftermarket, preferred over stud-mounts for engines seeing frequent use or higher valve spring pressures. The roller tip design is standard practice in modern performance engine building, reducing maintenance intervals and improving longevity. This kit's specification matches the demands of builders who reject compromise components in critical valve train positions.
