This is a Speedmaster roller rocker arm set designed for Chevy small-block (SBC) 350 engines with a 1.5 rocker ratio. The set features a shaft mount design and is constructed from stainless steel for durability and corrosion resistance. Roller rocker arms are commonly used in high-performance engine builds and rebuilds to reduce friction, improve valve actuation, and increase horsepower and reliability compared to stock stamped steel arms.
The 1.5 ratio specification means the rocker arms provide a 1.5:1 mechanical advantage on the valve lift, which is suitable for stock and mildly modified SBC 350 engines. The stainless steel shaft mount construction ensures longevity and stable performance in both street and racing applications. These rocker arms are ideal for engine builders, enthusiasts performing engine rebuilds, and anyone seeking to upgrade a Chevy 350 with improved valvetrain components.
