SBF Xtreme Hyd. Roller Cam XE266HR

The SBF Xtreme Hyd. Roller Cam XE266HR from COMP CAMS is designed for serious small-block Ford engine builders who require high-RPM reliability and aggressive valve lift. This hydraulic roller camshaft is suitable for both forced-induction and naturally aspirated street and strip applications, where valve train stability and consistent performance are essential. Whether you are constructing a street-strip cruiser or a dedicated drag platform, this cam provides the aggressive profile necessary to optimize intake and exhaust flow without compromising drivability or component longevity.

The XE266HR features a true roller design that reduces friction, minimizes lifter wear, and allows for sustained high-RPM operation beyond the limits of flat-tappet designs. The hydraulic roller technology eliminates the need for pre-load adjustment while ensuring automatic lash compensation across the powerband, which guarantees repeatable valve timing through thermal cycling and varying load conditions. The Xtreme series designation signifies that this cam incorporates COMP CAMS' advanced grinding technology and proprietary lobe profiles, optimized for maximum lift and duration, enhancing port velocity and cylinder-filling efficiency at peak RPM.

This camshaft is particularly beneficial for small-block Ford 289, 302, 347, and 408 stroker platforms that utilize modern hydraulic roller lifters and compatible valvetrain geometry. Proper pushrod length verification and rocker arm installation are required for optimal performance. With its design focused on high-RPM applications, the XE266HR is an excellent choice for those looking to maximize their engine's performance on the street or at the track.
