Upgrade your small-block Ford's valvetrain with the Speedmaster DNA® Aluminum Roller Rocker Arms Set (PN 1-261-006). Engineered specifically for Ford 289, 302, and 351 Windsor engines, these rocker arms feature a 1.6 ratio and 3/8" stud fitment, delivering improved valve lift and more efficient power transfer compared to factory stamped-steel rockers. The lightweight aluminum construction helps reduce valvetrain mass for better high-RPM response.
The roller tip design minimizes friction at the valve stem contact point, promoting longer valve and rocker wear life while supporting consistent performance under sustained use. Sold as a complete set, these DNA® series rocker arms are a straightforward bolt-on upgrade for enthusiasts looking to extract more performance from their small-block Ford build. Always verify compatibility with your specific engine configuration before installation.
