BBC Gen VI Xtreme Hyd. Roller Cam XR288HR-10

The BBC Gen VI Xtreme Hyd. Roller Cam XR288HR-10 from COMP CAMS is designed specifically for big-block Chevrolet engines that demand aggressive street and strip performance while maintaining streetability. This hydraulic roller camshaft is ideal for modified BBC platforms where both power delivery and reliability are crucial. Whether you're building a restomod, upgrading an existing big-block, or optimizing a performance engine for bracket racing, this camshaft provides the necessary lift and duration for significant horsepower gains.

As a Gen VI hydraulic roller design, the XR288HR-10 utilizes roller lifter technology to minimize friction and prevent the wear patterns typically associated with flat-tappet cams. This results in enhanced engine longevity and consistent performance over extended mileage. The Xtreme profile is engineered to maximize valve overlap and aggressive intake timing, which improves cylinder filling and scavenging, leading to increased volumetric efficiency.

This camshaft is particularly beneficial for BBC owners utilizing modern hydraulic roller valvetrain packages on 454, 427, or 496 cubic-inch platforms. Installation requires compatible roller lifters, pushrods, and a valvetrain geometry check to ensure proper clearances. The hydraulic actuation feature automatically compensates for thermal expansion and valve train wear, providing predictable, maintenance-free operation across various load conditions and ambient temperatures.
