SBC Roller Rocker Arms 1.5 Ratio 7/16 Stud

The SBC Roller Rocker Arms 1.5 Ratio 7/16 Stud set from Scorpion Performance is an essential upgrade for small-block Chevy engine builders and performance mechanics aiming to enhance valve train efficiency and reliability. These roller rocker arms are designed for high-RPM applications, making them suitable for both street performance builds and dedicated racing engines.

Featuring a 1.5:1 ratio, these rocker arms optimize valve lift and rocker arm geometry, allowing for effective cam profile utilization across a broad power band. The roller rocker technology minimizes friction and wear compared to traditional stamped steel arms by utilizing sealed roller bearings at the cam lobe contact point. The 7/16 inch stud configuration ensures compatibility with standard small-block Chevy cylinder head specifications, providing robust clamping force for sustained high-RPM operation.

These roller rocker arms are particularly beneficial for small-block Chevy platforms, enhancing performance in various applications, including classic muscle car restorations and modern performance builds. Scorpion Performance's precision manufacturing guarantees consistent ratio accuracy and durable needle bearings, which help reduce parasitic power loss and extend the life of valve train components.
