Hydraulic Roller Camshaft 212/22X .553/.553 107 LSA

The Brian Tooley Racing Truck Norris camshaft is engineered to deliver significant performance gains for 1999-2013 GM LS truck engines, including 4.8L, 5.3L, 6.0L, and 6.2L displacements. This camshaft is the result of extensive in-house cam lobe design and dyno testing, offering improved power and torque across the entire RPM range compared to previous V2 truck cam models. Key specifications for the Truck Norris camshaft include a 212 intake duration, 22X exhaust duration, .553 intake valve lift, .553 exhaust valve lift, and a 107-degree lobe separation angle. 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. While 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. Customers have noted a "choppy cold start" as a characteristic of this camshaft.
