Scorpion Performance 1038 SBC Roller Rocker Arms, 1.60 Ratio, 3/8-Inch Stud Mount

Upgrade your Small Block Chevy valvetrain with the Scorpion Performance 1038 roller rocker arm set. Designed for reliable high-performance operation, these narrow-body rocker arms use a 3/8-inch stud-mount configuration and a 1.60:1 ratio to help optimize valve lift and valvetrain geometry. The full-roller design reduces friction at the valve tip and pivot points, supporting smooth, consistent operation under demanding engine conditions.
The Scorpion Performance 1038 rocker arms are manufactured from lightweight aluminum and finished with a blue anodized surface for added durability and a distinctive appearance. Their narrow-body design provides added clearance in applications where space around the rocker assembly is limited, making them well suited for compatible Small Block Chevy cylinder heads and performance builds. Verify stud size, valve train geometry, pushrod clearance, and cylinder head compatibility before installation.
This set includes 16 rocker arms for complete coverage of a typical V8 application. The 1.60 ratio can increase valve lift compared with lower-ratio rocker arms, but final results depend on camshaft specifications, cylinder head design, pushrod length, and other engine components. Professional installation and proper adjustment are recommended to help ensure dependable performance and long service life. The Scorpion Performance 1038 is a practical choice for enthusiasts seeking lightweight, full-roller rocker arms for a Small Block Chevy engine.
