BBM Shaft Mount Roller Rockers 1.6 Ratio

The BBM Shaft Mount Roller Rockers 1.6 Ratio from PROFORM are designed for serious engine builders and performance enthusiasts looking to enhance valvetrain efficiency and reliability. These shaft-mounted roller rocker assemblies are ideal for high-performance and racing applications, providing superior geometry control and reduced friction compared to traditional rockers.

The 1.6:1 ratio design increases valve lift compared to stock 1.5:1 geometry, which can lead to improved performance characteristics. Roller tips minimize friction during valve operation, allowing for tighter lobe separation and more precise cam timing. The shaft-mount architecture ensures superior load distribution across multiple pivot points, reducing side loading that can occur with traditional bolt-down rockers.

These rockers are particularly beneficial for those building street performance engines, preparing for bracket racing, or restoring classic muscle cars with modern capabilities. Their durability supports aggressive cam profiles and higher RPM operation, making them a reliable choice for maximizing engine longevity and tuning flexibility.
