Tick Performance proudly offers our Elite Series of Camshafts designed specifically for 4.8L & 5.3L 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 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.
