BBM R/A & Shaft Kit - 1.5 Ratio w/EDE RPM Hds

The BBM R/A & Shaft Kit - 1.5 Ratio w/EDE RPM Heads is engineered for serious engine builders and performance enthusiasts focused on optimizing rocker arm geometry and valve train response. This complete shaft kit is essential for enhancing engine performance, particularly in small-block and mid-displacement engines.

The 1.5 rocker ratio in this assembly effectively multiplies cam lift by 1.5 times, which is crucial for maximizing valve opening duration and improving flow without necessitating an aggressive cam profile. When paired with EDE RPM heads, this kit ensures consistent valve seating geometry and minimizes deflection under load, enhancing combustion chamber efficiency.

This complete shaft kit is ideal for those looking to eliminate compatibility guesswork, as all components are matched for geometry and clearances. By preventing premature wear and performance loss associated with mismatched rocker assemblies, this kit provides a reliable solution for consistent power delivery across the RPM band.
