Upgrade your Ford small-block's valvetrain with Speedmaster's DNA® Aluminum Roller Rocker Arms (Part# 1-261-041). Designed specifically for the 289, 302, and 351 Windsor engines, these rocker arms feature a 1.6 ratio for increased valve lift over stock, helping unlock more power and throttle response from your small-block Ford. The aluminum construction keeps reciprocating mass low, while the roller tip design reduces friction and wear on the valve stems for improved durability and more consistent valvetrain geometry.
These rocker arms are built for 5/16" stud-mount applications, making them a direct-fit upgrade for compatible Ford SB Windsor configurations. Whether you're building a street performer or a dedicated track engine, Speedmaster's 1-261-041 DNA® Roller Rocker Arms deliver a reliable, performance-focused valvetrain solution backed by Speedmaster's commitment to quality engine components.
