BBC 8.1L Xtreme Hyd Roller Cam - XR264HR14

The BBC 8.1L Xtreme Hyd Roller Cam XR264HR14 by COMP CAMS is a high-performance hydraulic roller camshaft engineered for serious builders and operators who demand precision engine control. This camshaft is purpose-built for applications requiring extreme durability and consistent valve timing under demanding operational conditions. Whether you're assembling a tactical or military vehicle platform, a competition engine, or a high-reliability build where performance cannot falter, this roller cam delivers the consistent lift and duration characteristics necessary for mission-critical power delivery.

The XR264HR designation indicates this is a hydraulic roller design, which reduces friction and wear compared to solid or flat-tappet designs while maintaining precise valve actuation timing. The 8.1L specification suggests this camshaft is optimized for larger-displacement engine platforms common in full-size tactical and military vehicles. Hydraulic roller technology allows the cam to maintain consistent performance across varying RPM ranges and load conditions, critical for engines that must perform reliably under sustained operational stress. The roller profile reduces parasitic drag on the valvetrain, translating to improved efficiency and reduced heat generation during extended operation.

This camshaft is ideal for technicians, engine builders, and platform specialists working on full-size truck and heavy-duty applications where valve timing precision directly impacts reliability and performance longevity. Installation requires proper valve clearance setup, pushrod geometry verification, and timing chain alignment per manufacturer specifications. The BBC 8.1L Xtreme Hyd Roller Cam integrates with standard roller rocker systems and hydraulic lifter configurations, making it a drop-in solution for compatible 8.1L platforms when combined with appropriate supporting components and professional installation.
