Upgrade your Ford small block's valvetrain with the Speedmaster PCE261.1104.03 Aluminum Shaft Mount Roller Rocker Arm Set. Engineered specifically for Ford 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 build.
The shaft-mount design provides superior valvetrain stability and consistency compared to stud-mount rockers, reducing deflection under high-RPM conditions. The aluminum construction keeps rotating weight low, while the roller tip minimizes friction at the valve stem for improved durability and performance. An ideal upgrade for street performance, street/strip, and engine rebuilds on compatible Ford SB applications.
