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

The Sharp Rockers BBM R/A & Shaft Kit with 1.6 Ratio and EDE RPM heads is a heavy-duty rocker arm assembly engineered for Mopar B and RB-series engine builds running Edelbrock or Trick Flow cylinder heads. This shaft-mount design delivers the mechanical advantage needed for aggressive cam profiles while maintaining precise valve control across the RPM band. The 1.6 ratio amplifies valve lift, making it ideal for performance engine combinations that demand increased flow and stronger valve actuation.

Aluminum construction with orange anodizing provides corrosion resistance and positive part identification in the engine bay. The roller tip design minimizes friction during valve operation, reducing parasitic losses and extending component life under continuous load. Shaft-mount configuration ensures rigid geometry and consistent valve train geometry, critical for maintaining valve-to-piston clearance and preventing valve float at high RPM. This kit arrives as a complete assembly, ready for installation on compatible Edelbrock or Trick Flow head platforms designed for this ratio and mounting style.

Builders upgrading Mopar B and RB-series engines for street performance, bracket racing, or dyno applications rely on precision rocker systems to translate cam lift into maximum valve flow. The 1.6 ratio strikes a practical balance between mechanical advantage and rocker geometry stability, making it suitable for both stock displacement and stroker builds. Verify head compatibility and valve clearance before installation to ensure proper fit within your specific engine platform and cam combination.

Sharp Rockers specializes in aftermarket valve train components for vintage and modern muscle car applications. Their rocker designs are widely recognized in the Mopar performance community for consistent quality and compatibility across various head platforms. This BBM shaft kit represents a proven solution for builders seeking reliable valve train performance without custom fabrication.
