Product Details
✓TRUCK NORRIS NSR Camshaft - No Springs Required For 1999-2013 GM Gen3/4 LS Truck Engines 4.8, 5.3, 6.0, 6.2
✓Specs: 212/22X .498"/.498" 107 LSA 3 Bolt Pattern
✓BTR's new No Springs Required version of the immensely popular Truck Norris camshaft sacrifices only a slight amount of power from the original Truck Norris, in exchange for the convenience of being able to reuse your factory valve springs and pushrods. Please note that if your engine has high mileage we would still recommend replacing the springs for best performance, in which case the original Truck Norris Camshaft package with springs included would be an ideal option.
✓The Truck Norris Cam will deliver a roundhouse kick in the pants to your 1999-2013 GM V8 Truck or SUV! 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 BTR's legendary V2 truck cams. It has an idle sound similar to more aggressive truck camshafts, yet will behave well with stock torque converters.
