Upgrade your Ford 429 Boss engine with the Speedmaster PCE261.1244.03 Shaft Roller Rocker Arms Set. Featuring a performance 1.73 rocker ratio, these aluminum shaft-mount roller rockers are engineered to improve valve train geometry, reduce friction, and unlock more efficient power transfer compared to factory stamped-steel rockers.
The shaft-mounted design provides superior stability and consistent rocker alignment under high-rpm conditions, making this set an ideal choice for street performance and racing builds centered around the Ford 429 Boss. The lightweight aluminum construction helps reduce reciprocating mass while the roller tip minimizes wear on the valve stem for long-lasting, reliable performance.
