BTR Brian Tooley TRUCK NORRIS Camshaft For 1999-2013 GM Gen3/4 LS Truck Engines 4.8, 5.3, 6.0, 6.2

Specs: 212/22X .552"/.552" 107 LSA 3 Bolt Pattern

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.

If installing in an engine originally equipped with a 1-bolt camshaft, a 3 bolt conversion kit will be required. MAKE IT A KIT!

Our kit options take the guesswork out and include the following: Camshaft only: BTR Truck Norris Camshaft by itself. Camshaft, Springs and MM Hat Seals: BTR Truck Norris Cam, high quality beehive springs, MM hat valve seals. Camshaft, Springs, MM Hat Seals and Pushrods: BTR Truck Norris Cam, beehive springs, MM hat seals and 7.400" long, 5/16" Chromoly Pushrods with .080" wall thickness. MM Gasket kit: Includes Timing cover gasket, water pump gaskets, front crankshaft seal and new damper bolt

Driver Side (Part A) Only; GM GMC truck/SUV/Hummer LS ('99-'12), Header/Manifold -to-Exhaust Pipe, Driver Side, 1(each)

There are no rubber binders or composite materials in Remflex Exhaust Gaskets so they will not shrink or harden due to time or temperature eliminating the need to go back and continually retighten your flange bolts

Heating and cooling of the exhaust system causes header and manifold flanges to warp resulting in gaps between the head and header which Remflex exhaust gaskets seal completely due to the thickness and compressibility of the 100 percent flexible graphite

Remflex exhaust gaskets come in a standard 1/8 inch thickness and are designed to crush 50 percent allowing them to fill any pits or gaps in the flange surface up to 1/16 inch
