Tick Performance proudly offers our Elite Series of Camshafts designed specifically for 4.8, 5.3, LS2, LQ4 & LQ9 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.

Ever since we first released our Elite Series of Camshafts, one question has consistently been asked: which one is best for TOWING? Now, we're proud to release the all-new towMAX Camshafts, specifically designed for guys who tow and are looking for more power where they need it - UNDER the curve! This camshaft is perfect if you're looking to delete the factory DOD/AFM and VVT systems. We strongly suggest the use of our Tick/PAC Dual Valvesprings (although you can get away with using PAC #1219 drop-in springs) and hardened pushrods with this camshaft (sold separately.) Hundreds of hours were spent developing this camshaft to perform precisely the way we advertise, so as a result, changes to the LSA or any other specification of this camshaft are not available. Option Guide: Do I need the 3-Bolt Conversion Kit?In 2007, GM began installing a camshaft in select LSx engines that used one large bolt to attach the timing chain gear. All Tick Performance Elite Series Camshafts use 3 bolts to attach the timing chain gear, as the earler LSx engines used. If your engine is a 2007 or newer (or if you're not sure which camshaft style you've got), we suggest adding the 3-Bolt Conversion Kit during checkout for an extra $24.99. This Conversion Kit includes everything that you'll need to convert your single-bolt setup over to the 3-Bolt setup (the proper timing chain gear and a set of 3 ARP camshaft bolts.) If you'd prefer to retain the single bolt style camshaft (not recommended), please place your order with us via phone. 1x GM 12586481, 1x ARP 134-10 03
