Hydraulic Roller Cam - SBC XR269HR-12

The COMP CAMS Hydraulic Roller Cam SBC XR269HR-12 is a high-lift, long-duration camshaft engineered for GM LT-Series engines from 1992 to 1997. This hydraulic roller cam delivers 0.495-inch intake and 0.503-inch exhaust lift across a 269/276-degree duration window with a 112-degree lobe separation angle, optimized for sustained power delivery between 1500 and 5500 RPM. The Xtreme Energy series from COMP CAMS represents a proven platform for street and strip performance in classic GM small-block and LS-based applications.

Hydraulic roller cam technology eliminates the maintenance burden of mechanical adjusters while maintaining precise valve timing control. The 269/276 duration specification—split between intake and exhaust events—creates an aggressive intake bias that maximizes cylinder filling at mid-range RPMs without sacrificing low-end response. The 112-degree LSA (lobe separation angle) sits in the moderate overlap zone, balancing street driveability with measurable power gains. This camshaft pairs with compatible valvetrain components and requires proper spring pressures and lifter clearances to function reliably over extended use.

This cam is purpose-built for enthusiasts seeking noticeable performance increases in carbureted or fuel-injected LT-Series engines without full-heads-and-intake package costs. The 1500–5500 RPM power band suits both street cars and weekend track duty. Proper installation—including verification of deck height, piston-to-valve clearance, and valve spring installed height—is essential. The Xtreme Energy XR269HR-12 remains a recognized choice in the GM small-block performance segment for builders prioritizing mid-range torque and consistent reliability.
