BC adjustable cam gears deliver the easiest way to dial in more horsepower and/or torque without getting underneath the valve cover, disassembling the engine or dealing with onboard electronics. 

• BC gears are CNC machined from aerospace grade, 6061-T6 billet aluminum for ultimate tensile strength. 
  
• Easy to read, laser etched face features micrometer style markings for precise adjustment (up to 10 degrees in each direction) and quick tunability. 
  
• Each hub is held down by four ARP hex bolts for maximum clamping ability. 
  
• Hard anodized finish prevents premature surface wear.
  
• Sold as a set of 2 cam gears
  

Note: To insure proper fit of the gear hub and the camshaft snout, place gear under hot water to expand the center hole diameter, then place on the camshaft.
