SBM Shaft Mount Roller Rockers 1.6 Ratio

The SBM Shaft Mount Roller Rockers 1.6 Ratio are designed specifically for serious engine builders and automotive enthusiasts looking to enhance the performance of small-block Chevrolet engines. These roller rockers provide a reliable upgrade to stock rocker arm assemblies, focusing on durability and efficiency.

Constructed to handle increased lift and duration demands, these shaft mount roller rockers replace traditional stamped steel rockers, significantly reducing friction and improving valvetrain efficiency. The 1.6 ratio geometry allows for greater valve opening without sacrificing low-end torque or engine longevity, while the roller bearing design minimizes wear on pushrods and rocker arms.

Ideal for small-block rebuilds, these rockers excel in applications where valvetrain precision is crucial. Proper installation requires careful calculation of pushrod length and valve lash adjustment to ensure reliability and performance. With their robust design, these rockers are a top choice for those aiming for consistent valve actuation in high-RPM scenarios.
