SBC Hydraulic Cam CS-252BH-11

The SBC Hydraulic Cam CS-252BH-11 from COMP CAMS is a purpose-built hydraulic roller camshaft engineered for small-block Chevrolet engines seeking reliable, maintenance-free valve actuation. This cam is designed for builders and enthusiasts who prioritize streetable performance without the complexity of mechanical lifter systems. The hydraulic design automatically compensates for thermal expansion and wear, eliminating the need for valve lash adjustments and making it ideal for both naturally aspirated and boosted small-block platforms that demand durability.

The CS-252BH-11 specification delivers solid mid-range torque and power characteristics through its carefully profiled lobe design and hydraulic roller follower technology. The hydraulic roller cam operates with reduced friction compared to flat-tappet designs, improving thermal efficiency and fuel economy while enabling tighter, more aggressive lobe profiles without sacrificing reliability. COMP CAMS' proprietary manufacturing ensures consistent lobe geometry and surface finish across the entire camshaft, preventing premature wear on both the cam and lifter faces. The compact 3.1-inch profile and 9.31-pound weight integration into standard small-block Chevrolet engine packages means drop-in compatibility with most SBC cylinder heads and block configurations.

Mechanics and engine builders trust the SBC Hydraulic Cam CS-252BH-11 for street machines, daily drivers, and moderate performance builds where valve train stability matters. Installation requires standard hydraulic lifters and a timing chain system compatible with small-block Chevrolet specifications; the camshaft indexes with OEM reluctor rings and sensor configurations on modern EFI applications. This cam pairs effectively with stock or mildly ported heads, standard intake manifolds, and 3,500–6,000 RPM operating windows typical of street and strip combinations. For SBC engine builders targeting balanced power delivery without exotic components, the CS-252BH-11 delivers proven performance at a competitive price point.
