BTR LS Truck Norris NO SPRINGS REQUIRED Camshaft

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.
