SBC Rocker Arm Set - 1.52 Ratio 3/8 Stud

The COMP CAMS SBC Rocker Arm Set with 1.52 Ratio and 3/8 Stud is a full roller design engineered for small block Chevy engines requiring premium valve actuation. This 16-piece chromoly rocker arm set delivers the mechanical precision and durability demanded by performance engine builders and serious enthusiasts who rely on consistent valve lift and timing across all 16 cylinder events. The 1.52 ratio provides the mechanical advantage necessary for aggressive valve opening while maintaining structural integrity under high-RPM operation.

The full roller design minimizes friction at the pushrod interface, reducing parasitic losses and heat generation during extended operation. The 3/8-inch stud mount configuration ensures compatibility with standard SBC applications without requiring custom preparation. Chromoly construction provides the strength-to-weight balance required for high-lift, high-duration cam profiles while resisting wear at the roller contact point. The 1.52 ratio multiplier extends valve opening distance relative to pushrod travel, allowing camshaft designers to optimize timing events with smaller lift values—a critical advantage in naturally aspirated engines where every degree of crankshaft rotation affects power delivery.

This rocker arm set is engineered for small block Chevy platform builds—street performance, bracket racing, marine applications, and off-road powerplants that demand repeatable valve control. Buyers choosing a complete 16-piece set eliminate the risk of mixing rocker types or ratios across different cylinders, ensuring balanced performance across the entire engine. The set is installed as a complete matched assembly, simplifying quality control and troubleshooting during engine assembly and break-in.

COMP CAMS is recognized in the performance engine industry for precision valve train components. SBC rocker arms in this specification are OEM-compatible in mounting but deliver aftermarket performance characteristics, making them a practical choice for builders upgrading factory valve actuation or completing custom small block builds. Whether assembling an entry-level street engine or a dedicated competition platform, this rocker arm set provides the foundation for reliable, high-RPM valve control.
