  • Good mid-range power - Good performance increase - Largest with stock converter
  • Xtreme 4X4â„¢ -Due to the allowances of lower engine speed, these designs are slightly more aggressive than the original Xtreme Energyâ„¢ Hydraulic Rollers. Great low and mid-range torque. They are one of our most aggressive hydraulic Roller lobes and run well in street, off-road and four-wheeling.
  • WARNING: Camshaft Optimized for use with a Melanized or Nitrided distributor Gear. Not compatible with cast or Steel Gears without similar surface treatments. Failure to utilize the proper distributor Gear will void all warranties and/or return policies.
    • 1: Cams for '55-'57 engines can be custom ordered. 2: The '87+ Chevy Small Block received provisions for Roller lifters. Most '87 - '93 GM cars came with Roller lifters, but most '87 - '95 trucks came with flat tappet lifters in Roller lifter style blocks. If your block has '87+ OEM-style Roller Cam provisions but does not have Roller components fitted, COMP Hydraulic Roller Lifter Install Kit for '91-'02 Blocks can be purchased. As well as a '87+ OE-Style COMP Hydraulic Roller Cam.
