Xtreme Hyd. Roller Cam - SBC XR264HR

The Xtreme Hyd. Roller Cam - SBC XR264HR by COMP CAMS is purpose-built for small-block Chevy enthusiasts and professional engine builders seeking measurable performance gains without sacrificing reliability or drivability. This hydraulic roller camshaft addresses the core need for increased valve lift and duration while maintaining the smooth, consistent valve train control that modern street and strip engines demand. Whether you're building a restomod, upgrading a weekend warrior, or optimizing a racing engine, this cam delivers the aggressive profile necessary to unlock additional horsepower and torque from your SBC platform.

Engineered with COMP CAMS' proven hydraulic roller technology, the XR264HR features precision-ground lobes and hardened steel construction designed to withstand sustained high-RPM operation and repeated valve train cycles. The roller lifter design significantly reduces friction losses compared to flat-tappet designs, improving efficiency and reducing heat generation—critical factors in engines pushed beyond stock parameters. This cam's specific lift and duration characteristics are optimized to work in conjunction with quality valve springs, pushrods, and rocker arms, ensuring proper valve control throughout the entire RPM band. The hydraulic roller mechanism automatically adjusts for thermal expansion and mechanical wear, eliminating manual lash adjustments and providing consistent performance across varying operating conditions.

This camshaft is ideal for small-block Chevy engines running hydraulic roller valve train configurations, including popular displacements from 262 to 400 cubic inches. Installation requires a compatible hydraulic roller lifter set and appropriate valve spring pressures to prevent float at peak RPM—consult COMP CAMS' specifications or your engine builder before ordering. The XR264HR suits street performance, truck applications, and dedicated racing builds where reliability and consistent power delivery matter as much as peak output. Proper installation by experienced technicians and adherence to recommended supporting modifications will ensure optimal results and engine longevity.
