## Overview

The BTR Brian Tooley Racing Truck Norris NSR Camshaft is a high-performance camshaft designed for 1999-2013 GM Gen 3/4 LS truck engines (4.8L to 6.2L). Featuring a 212/22X duration and .498" lift, it boosts power and torque across the RPM range while allowing reuse of factory valve springs for easier installation. Developed through extensive testing, it delivers aggressive sound and superior performance without requiring spring upgrades, making it the ideal upgrade for enthusiasts seeking reliable, hassle-free power gains.

## Description

Developed from the success of the original Truck Norris, this NSR (No Springs Required) camshaft will deliver a roundhouse kick in the pants to your 1999-2013 Silverado or Sierra. 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 our legendary V2 truck cams.

Review: GREAT CAM - Great cam. I must have for your LS engine. 5 star rating for the BTR TRUCK NORRIS NSR CAM.
Review: Good chop, reliable valvetrain - Everyone always wants the biggest most gnarly cam you can get and don't know about the drop in valvetrain life. The truck Norris gives a nice chop but doesn't kill your valve train like the bigger cams, I've used several of these and it's my go to for any build not going exclusively to the track. I'd still change to the ls6 springs just to add some safety because the stick springs don't love higher rpm

## Features

- TRUCK NORRIS NSR Camshaft - No Springs Required For 1999-2013 GM Gen3/4 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 Cam 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.
