The Truck Norris NSR Camshaft is a game-changer for any 1999-2013 GM Gen3/4 LS Truck engine owner looking to unleash their vehicle's full potential.

With its No Springs Required design, you can save money and hassle by reusing your factory valve springs and pushrods.

Despite sacrificing only a slight amount of power compared to the original Truck Norris camshaft, this new version delivers even more power and torque across the curve thanks to extensive in-house design and dyno testing.

The idle sound is similar to more aggressive truck cams, yet it behaves well with stock torque converters.

Plus, it's compatible with VVT engines (requiring a VVT delete kit) and DOD/AFM engines (requiring a DOD delete).

Don't settle for mediocrity – upgrade to the Truck Norris NSR Camshaft today and experience the roundhouse kick in the pants your engine deserves!
