Xtreme Energy Hyd. Cam - SBM XR280HR-10

The Xtreme Energy Hyd. Cam - SBM XR280HR-10 by COMP CAMS is a high-performance hydraulic flat-tappet camshaft engineered for small-block Mopar engines demanding reliable mid-range torque and street-strip versatility. This cam is built for enthusiasts and mechanics who want proven power gains without the complexity of solid-roller conversions, making it ideal for daily drivers and weekend warriors alike. The hydraulic design eliminates the need for expensive valvetrain modifications while delivering the aggressive lift and duration profile that modern performance drivers expect.

This camshaft leverages COMP CAMS' precision manufacturing to provide consistent valve timing and lift across the entire RPM range, with hydraulic roller lifters that automatically maintain zero-lash clearance for durability and reduced noise. The XR280HR-10 profile is optimized for engines running stock or mildly modified cylinder heads and intake manifolds, delivering strong low-end response while extending usable power well into the mid-range. Its durable cast-iron construction resists wear and maintains geometric accuracy, ensuring reliable performance over thousands of heat cycles and high-RPM passes.

This cam is purpose-built for small-block Mopar applications—including 318, 340, and 360 variants—and pairs seamlessly with factory or performance intake and exhaust systems. Installation requires standard camshaft bearing surfaces and compatible lifters; no special machine work or exotic hardware is necessary, making it accessible for both professional shops and home garage builds. Whether you're rebuilding a classic muscle car or upgrading a street performer, the Xtreme Energy Hyd. Cam delivers proven horsepower gains with the reliability that serious builders trust.
