It’s optimized for towing, passing, and everyday drivability while delivering a deep, authoritative exhaust tone.

Turn your truck into a low‑end torque machine with the BTR Truck Norris cam. With .552/.552″ lift, 212/22x duration and a 107° LSA, this grind moves power into a thick, usable midrange across a wide 1800–6600 RPM band and is dyno‑proven at ~+57 HP / +16 lb‑ft on a 5.3L test. It’s built for towing, roll‑on passing and confident highway performance with a deep, authoritative exhaust note.

This kit bundles the Truck Norris cam with Redline .625″ beehive valve springs (steel retainers & locks), 16 premium valve stem seals, and a full set of 16 hardened 7.400″ pushrods (.080″ wall) to control valve motion, resist float, and ensure long‑term valvetrain reliability. Components are chosen to work together for proper geometry and durability on Gen III/IV truck builds.

Ideal for truck owners and installers who want a focused, install‑friendly power upgrade: fewer parts to source, correct valvetrain components included, and a cam tuned for real‑world torque and driveability. Professional installation and tuning recommended to maximize results.

• 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.
