BTR Truck Norris Camshaft Kit for Gen 3/4 LS Trucks – Springs, Seals & Pushrods (4.8–6.2L)

Truck Norris Camshaft Kit for Gen 3/4 LS Trucks

The Truck Norris camshaft kit represents months of hands-on R&D from the Brian Tooley Racing team. After countless designs, Spintron sessions, and Superflow engine dyno tests, the team delivers a profile designed to move your GM Gen 3/4 LS truck or SUV with confidence. The goal was a cam that broadens usable power while preserving street manners, idle quality, and compatibility with common drivetrains. The resulting profile aims to provide a strong, broad torque curve and a satisfying throttle response without sacrificing driveability.

The Truck Norris is built for 1999–2013 GM Gen 3/4 LS Truck engines, including 4.8, 5.3, 6.0, and 6.2 liter variants. The cam's specifications are 212/22X duration, lift of .552 inches on both ramps, and a 107 degree LSA behind a 3-bolt pattern, designed to fit standard kit configurations. The combination targets a broader power band and improved torque delivery across the RPM range, with a deeper, more purposeful idle that remains suitable for a street setup when paired with a stock torque converter in many configurations.

Key considerations and notes

• VVT engines will require a VVT delete kit to operate with this cam profile.
• If your engine originally used a 1-bolt cam, a 3-bolt conversion kit will be needed for proper fitment.

Why this Cam Stands Out

• Hundreds of hours of in-house cam lobe design and dyno testing informed this profile, targeting broader power and stronger torque in real-world driving.
• The idle retains a confident, purposeful feel that blends well with many street setups, while still delivering an assertive throttle response when you roll into it.
• The cam is paired with a robust valve-train kit, including springs, seals, and pushrods, designed to work together in Gen 3/4 LS trucks.
• Dyno-verified development helps translate into practical, usable performance gains across daily driving, spirited passes, and highway merging scenarios.

What You Get and How to Use It

• Camshaft designed for 1999–2013 GM Gen 3/4 LS Truck engines (4.8, 5.3, 6.0, 6.2).
• Includes springs, seals, and pushrods to support installation and durability.
• Clear compatibility notes: VVT delete recommended for VVT engines; 1-bolt to 3-bolt conversion as needed.

In practical terms, Truck Norris aims to deliver a more responsive feel throughout the power band, improved throttle response, and a satisfying engine character. As with any performance upgrade, results depend on the complete setup, including intake, exhaust, and tuning. Consider this a possible pathway to enhanced driving enjoyment rather than a guaranteed outcome. If you’re upgrading your Gen 3/4 LS truck, Truck Norris provides a proven, well-documented option to explore, with a balance of power, sound, and drivability that many enthusiasts appreciate during daily driving and weekend sessions alike.
