SBC Rocker Arms (8pk) 1.5 Ratio 7/16 Stud

The SBC Rocker Arms (8pk) 1.5 Ratio 7/16 Stud are precision-engineered valve train components designed specifically for small-block Chevrolet engines seeking improved performance and reliability. This eight-piece set is ideal for engine builders, hot rodders, and enthusiasts who demand OEM-compatible construction with enhanced durability for street, strip, or racing applications.

Manufactured by ELGIN under the Black Ice product line, these rocker arms feature a 1.5:1 mechanical advantage ratio, which increases valve lift relative to camshaft lift—resulting in improved valve opening and closing response. The 7/16-inch stud mount design ensures secure fastening to small-block Chevy cylinder heads using OEM-pattern long-slot configuration for alignment flexibility. Constructed from hardened steel, these rocker arms deliver superior wear resistance and maintain consistent geometry under sustained high-RPM operation.

This rocker arm set is perfect for small-block Chevrolet builders modernizing classic muscle cars, street rods, or race engines requiring bolt-on performance upgrades without major cylinder head modification. The long-slot design accommodates minor pushrod length variations during installation, making it a versatile choice for various engine builds.
