Product Details

The COMP Cams Xtreme Energy Solid Roller Camshaft line is built for small block Chevy engines. It is for builders who want strong mid-range and top-end power from a solid roller cam, also called a mechanical roller cam. The Xtreme Energy series is designed for street/strip, bracket racing, and other performance builds.

Key Features:

  • Solid roller lifter design for aggressive lobe profiles and high-RPM valvetrain stability
  • Xtreme Energy lobe designs aimed at improved throttle response and a broad power band
  • Precision-ground lobes made to COMP Cams quality standards
  • Multiple grind options in the series to suit different engine combinations and power goals
  • Intended for use with matched roller lifters, valve springs, and related valvetrain components

Solid roller camshafts need a properly matched valvetrain. Pair the cam with compatible roller lifters, pushrods, springs, and rocker arms. COMP Cams is a well-known name in performance camshafts and valvetrain parts, and the Xtreme Energy line is a popular choice for small block Chevy builds. Each part number in the line has its own specifications and grind.
