SBC Roller Rocker Arms 1.3 Ratio 3/8 Stud

The SBC Roller Rocker Arms 1.3 Ratio 3/8 Stud from Scorpion Performance are designed for small-block Chevrolet engine builders who prioritize reliable valve actuation and consistent lift geometry. These roller rocker arms cater to serious automotive enthusiasts and professional mechanics involved in rebuilding classic muscle cars, street rods, and performance engines where durability and precision are essential.

Featuring a 1.3:1 ratio, these rocker arms provide a balanced approach to valve motion while maintaining practical valve train geometry suitable for various applications, including street and bracket racing.

These SBC Roller Rocker Arms are particularly beneficial for builders looking to enhance their engine's performance without the need for extensive modifications. The 3/8 stud mounting configuration is compatible with factory and most popular aftermarket SBC cylinder heads, ensuring a straightforward installation process. Scorpion Performance's robust construction is engineered to withstand the demands of solid-roller camshaft loads and high-rpm valve spring pressure, making them a reliable choice for high-performance builds.
