Speedmaster Chevy SBC 350 1.6 Ratio Aluminum Shaft Mount Roller Rocker Arm PCE261.1099

The Speedmaster PCE261.1099 is a roller rocker arm assembly engineered for Chevy SBC 350 engines, delivering a 1.6 rocker ratio with aluminum construction and shaft mounting design. This component features a .100 intake offset and combines durable aluminum with roller technology to reduce valvetrain friction and improve engine performance.

Shaft-mount roller rocker arms like this are essential for high-performance and modified SBC builds, offering consistent valve actuation and reduced wear compared to traditional rocker designs. The 1.6 ratio amplifies valve lift, making it suitable for applications requiring enhanced breathing and responsive engine characteristics. The aluminum construction keeps weight low while maintaining the structural integrity needed for demanding engine conditions.

Key Features & Benefits

• 1.6 Rocker Ratio: Increases valve lift for improved engine breathing and performance in SBC 350 applications.
