Engineered for small block Chevy 350 applications, the Speedmaster DNA® Aluminum Roller Rocker Arms Set (1-261-017) features a 1.5 ratio design to deliver consistent valve actuation and improved valvetrain efficiency over stock stamped-steel rockers. The aluminum construction helps reduce reciprocating mass, while the roller tip and roller fulcrum minimize friction for enhanced durability and more reliable power transfer under demanding conditions.
Designed as a complete shaft-mounted set, these rocker arms provide superior stability and precise geometry compared to stud-mounted alternatives, making them a strong upgrade for street performance and track use on SBC 350 engines. Always verify compatibility with your specific cylinder head and valvetrain components before installation.
