BTR GEN III & IV LS TRUCK NORRIS NSR CAM
Specs: 212/22X, .498/.498, 107 LSA
Developed from the success of the original Truck Norris, this NSR (No Springs Required) camshaft will deliver a roundhouse kick in the pants to your 1999-2013 Silverado or Sierra. Developed from hundreds of hours of in house cam lobe design and dyno testing, this camshaft has more power and torque everywhere in the curve compared to our legendary V2 truck cams.
