Tick Performance proudly offers our Elite Series of Camshafts designed specifically for LS1 & LS6 Engines! Using the latest and greatest technology available, we've put together a complete line of Camshafts that are designed to meet every goal, from mild to wild. Our Elite Series of Camshafts are all manufactured by COMP Cams or Cam Motion and are updated with a new version every time an advancement in valvetrain technology becomes available, so they're ALWAYS cutting-edge! Although we suggest measuring for piston-to-valve clearance during ANY camshaft install, every Elite Series Camshaft is designed to fit in a stock engine & stock heads with adequate clearance unless otherwise noted. These cams are designed to maximize power, reliability and valvetrain longevity.
