It utilizes a hydraulic roller design and a three-bolt cam bolt pattern, making it suitable for Gen III and Gen IV LS engine combinations. The product is also identified by EMS Code 3 and BTR SKU TRUCKNORRIS.\n\nWhile the base camshaft is available, it is often recommended to consider compatible components for optimal performance and reliability. Related products such as BTR LS Truck Cam Kits, valve spring kits, valve seals, and stock replacement pushrods are frequently purchased alongside the Truck Norris camshaft to ensure a complete and effective upgrade.
