SBC Roller Tip R/A's - 1.5 Ratio 3/8in Stud

The SBC Roller Tip R/A's - 1.5 Ratio 3/8-inch stud from ELGIN are designed for small-block Chevrolet engine builders and performance enthusiasts seeking reliable valve actuation at higher RPM ranges. These roller-tip rocker arms provide a precision upgrade that enhances engine performance and efficiency.

Engineered to reduce friction at the pushrod interface, these rocker arms ensure consistent valve lift and duration across the powerband. The 1.5 ratio geometry translates lifter motion into precise valve events, while the hardened roller tip minimizes wear compared to flat-face designs, extending component life under aggressive cam profiles.

These rocker arms are compatible with any small-block Chevrolet application, from 283 ci to 400 ci displacement, particularly when using an aftermarket camshaft. Engine builders upgrading from factory stamped steel rocker arms can expect improved valve sealing and better overall engine response.
