BBC Gen VI Xtreme Hyd. Roller Cam XR300HR-10

The COMP CAMS BBC Gen VI Xtreme Hydraulic Roller Cam XR300HR-10 is a high-performance camshaft designed specifically for big-block Chevrolet engines. It is ideal for those looking to enhance their engine's performance while maintaining street drivability. This camshaft is perfect for both track-focused builds and weekend warriors, providing a balance between aggression and reliability.

The hydraulic roller design of the XR300HR-10 utilizes oil pressure to maintain zero lash automatically, which eliminates the need for constant valve adjustments. This feature reduces wear on lifters and pushrods compared to solid lifter designs. The "Xtreme" designation signifies aggressive cam profiles that optimize airflow and cylinder filling at higher RPMs, enhancing overall engine performance.

Engine builders will appreciate the precision manufacturing of COMP CAMS, which ensures tight tolerances on lobe profiles and base circle concentricity. This camshaft is suitable for applications running RPM ranges from 2500 to 6000+, whether naturally aspirated or boosted. Proper installation requires compatible hydraulic roller lifters, a quality timing chain set, and attention to valve train geometry for optimal performance.
