Upgrade your Big Block Chevy 454 valvetrain with the Speedmaster DNA® Aluminum Roller Rocker Arms Set (PN 1-261-019). Featuring a 1.7 rocker ratio and a shaft-mount design, these roller rockers are engineered to reduce friction, improve valve actuation consistency, and handle the demands of high-performance street and race applications on BBC 454 engines.
The aluminum construction keeps reciprocating mass low while the roller tip and shaft-mount configuration provide precise, repeatable rocker geometry compared to traditional stud-mount setups. Sold as a complete set, these rockers are a direct performance upgrade for your Big Block Chevy 454 build.
