Product Description
TRUCK NORRIS NSR Camshaft - No Springs Required
For 1999-2013 GM Gen 3/4 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 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.
This listing is for the Truck Norris NSR camshaft by itself. No Springs or Pushrods included.
Optional Installation Gasket Kit: Includes Timing cover gasket, water pump gaskets, front crankshaft seal and new damper bolt.
Please Note:
-
VVT engines will require a VVT delete kit.
-
If installing in an engine originally equipped with a 1-bolt camshaft, a 3-bolt conversion kit will be required.
-
DOD/AFM engines will require a DOD delete to install any aftermarket camshafts.
