SBC Rocker Arm - 1.6 Ratio 3/8 Stud

The SBC Rocker Arm - 1.6 Ratio 3/8 Stud from Sharp Rockers is a precision-engineered rocker arm assembly designed for small-block Chevrolet engines requiring reliable valve actuation and improved performance characteristics. This full roller rocker arm serves as a direct replacement or upgrade for OEM setups, offering enhanced durability and consistent mechanical advantage for both street and performance applications. Small-block Chevy enthusiasts and engine builders choose this component to optimize valve timing geometry and reduce friction losses in their powerplants.

Constructed from aluminum with an orange anodized finish for corrosion resistance and visual distinction, the SBC Rocker Arm features a 1.6:1 ratio that multiplies pushrod motion by 60%, delivering precise valve lift with mechanical efficiency. The full roller design minimizes friction between rocker arm and valve stem, reducing parasitic power loss and heat generation during sustained engine operation. A 3/8-inch stud mount provides secure, repeatable installation to standard small-block Chevy cylinder heads, ensuring proper alignment and eliminating valvetrain noise associated with wear or deflection.

This rocker arm is ideal for builders upgrading stock valvetrain components, restoring classic muscle cars with modern reliability, or fine-tuning performance builds where valve motion geometry directly impacts horsepower and throttle response. Installation is straightforward on any small-block Chevy engine with 3/8-inch stud bosses; rocker arms are sold individually, allowing for complete set replacement or targeted upgrades to match cam profiles and spring rates. The compact dimensions and modest 0.38 lb weight make handling and installation efficient for both professional engine shops and dedicated home mechanics.
