SBM Shaft Mount Roller Rockers

The SBM Shaft Mount Roller Rockers (MPN 440-869) are a precision valve train upgrade designed for high-performance engine builders and automotive enthusiasts. These roller rockers aim to reduce friction and wear in the valvetrain, enhancing overall engine efficiency and reliability. They are particularly suited for applications that require reduced parasitic losses and improved valve control.

Engineered with precision needle bearings, these roller rockers significantly decrease friction compared to traditional stamped steel rocker arms. This design allows for smoother rotation across the valve stem tip, minimizing binding and wear associated with sliding contact. Such features are essential for both street and competition engines, where valve timing accuracy and consistent lift characteristics are crucial for optimal combustion efficiency and engine longevity.

Engine builders, performance shops, and dedicated enthusiasts preparing engines for serious street or track use will find these roller rockers beneficial. Proper installation requires attention to shaft alignment and the use of quality fastening hardware to ensure optimal performance. With robust construction and tight tolerances, these roller rockers are built to withstand demanding thermal and pressure cycles.
