The LS1/LS6 Xtreme RPM High Hyd. Roller Cam XR275HR from COMP CAMS is designed for LS-platform enthusiasts who demand high RPM capability and aggressive valve timing. This hydraulic roller cam is specifically engineered for high-revving applications, providing the reliability and performance required by street machines, track cars, and forced-induction builds.
The XR275HR cam utilizes hydraulic roller technology, which reduces friction compared to traditional flat-tappet designs while ensuring precise valve control across the RPM range. Its optimized lobe geometry and durable metallurgy guarantee consistent lift and duration, making it suitable for extreme engine speeds. The roller design also self-adjusts for thermal expansion, minimizing maintenance needs.
This cam is compatible with both stock and aftermarket LS1/LS6 cylinder heads and works well with carbureted and fuel-injected setups, making it versatile for various LS swap projects. Builders targeting high-revving powerplants exceeding 6,500 RPM will find the XR275HR particularly beneficial. Installation follows standard LS cam installation procedures.
