SBC Roller Rocker Arms - 1.6 Ratio- 3/8in Stud

The PROFORM SBC Roller Rocker Arms with 1.6 Ratio and 3/8-inch Stud Mount represent a full roller design engineered for small block Chevy engines seeking improved valve actuation efficiency. This set of 16 aluminum rocker arms features blue anodized construction and self-aligning geometry, delivering consistent lift across the entire valve train while reducing friction and parasitic losses compared to stock arm assemblies. The 1.60 ratio provides a direct mechanical advantage that increases valve lift relative to camshaft lift, resulting in improved flow characteristics and broader powerband response across the engine's operating range.

The full roller design minimizes wear on valve stems and camshaft lobes by employing a rolling contact surface rather than sliding contact. The 3/8-inch stud mounting pattern maintains compatibility with standard small block Chevy cylinder head configurations, while the self-aligning feature accommodates minor variations in pushrod angle without binding or premature wear. Aluminum construction keeps reciprocating mass low, allowing higher engine speeds and reducing valvetrain stress. The blue anodized finish provides both corrosion resistance and visual identification, distinguishing these precision components within the engine bay.

These rocker arms suit builders and restorers upgrading small block Chevy valvetrains for increased performance, whether for street applications, bracket racing, or vintage restoration projects prioritizing period-correct roller technology. The complete set of 16 arms covers a full small block Chevy cylinder count, eliminating the need for multiple purchases. PROFORM's focus on street and performance applications makes this set a reliable choice for anyone seeking to improve breathing and responsiveness in an established small block Chevy platform.
