SBC Xtreme Hyd. Roller Cam XR282HR

The SBC Xtreme Hyd. Roller Cam XR282HR from COMP CAMS is a hydraulic roller camshaft engineered for small block Chevrolet engines seeking enhanced mid-range and top-end power delivery. This camshaft is designed for enthusiasts and engine builders who want to maximize performance without sacrificing streetability or reliability. The hydraulic roller design eliminates the need for manual valve lash adjustment, making it ideal for both carbureted and fuel-injected applications where ease of installation and consistent operation matter.

This camshaft features a 282-degree intake and 288-degree exhaust duration at 0.050-inch lift, with maximum valve lifts of 0.510 inches on the intake side and 0.520 inches on the exhaust side. The 110-degree lobe separation angle (LSA) provides an optimal balance between overlap and cylinder charging efficiency, while the 2,200 to 5,800 RPM power band targets responsive acceleration and sustained high-RPM performance. The hydraulic roller design reduces friction and wear compared to flat-tappet alternatives, delivering improved durability and repeatability across extended engine life. Precision-ground lobes and premium materials ensure consistent lift profiles and reliable operation under demanding conditions.

The SBC Xtreme Hyd. Roller Cam XR282HR is ideal for small block Chevy engines in performance street cars, mild-to-moderate racing applications, and engine rebuilds where balanced power and reliability are priorities. Installation requires a compatible hydraulic roller lifter set and standard cam installation procedures; ensure your engine features a roller-ready block and matching rocker arm geometry. This camshaft pairs well with quality valve springs, pushrods, and intake manifolds tuned for the 2,200–5,800 RPM power range, delivering noticeable gains in throttle response and overall engine character.
