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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BLTCSKSV | | Best Sellers Rank | #170,946 in Automotive ( See Top 100 in Automotive ) #44 in Car Camshafts | | Brand | Dynosty | | Date First Available | 11 November 2022 | | Exterior | Machined | | Item Weight | 5.15 Kilograms | | Item model number | BTR Truck Norris NSR | | Manufacturer | BTR Brian Tooley Racing | | Manufacturer Part Number | Truck Norris NSR | | Model | BTR Truck Norris NSR | | Package Dimensions | 56.39 x 9.65 x 7.37 cm; 5.15 kg | ## Images ![Brian Tooley Racing Truck Norris NSR Camshaft No Springs Required for Gen 3/4 LS 4.8 5.3 5.7 6.0 6.2 LS1 1999-2013 Vortec (Cam Only) - Image 1](https://m.media-amazon.com/images/I/61P2YkH+MQL.jpg) ## Frequently Bought Together - BTR Brian Tooley Racing Truck Norris NSR Camshaft No Springs Required for Gen 3/4 LS 4.8 5.3 5.7 6.0 6.2 LS1 1999-2013 Vortec (Cam Only) - Camshaft Retainer Plate Gasket Compatible with LS Series Engines, &Bolt Kit ARP 134-1003 Gen III IV V for GM LS1 LS2 LS3 4.8 5.3L 6.0L 6.2L Vortec Corvette Cam - FEL-PRO TCS 45993 Engine Timing Cover Gasket Set for Chevrolet Silverado 1500 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/515728355-brian-tooley-racing-truck-norris-nsr-camshaft-no-springs-required](https://www.desertcart.us/products/515728355-brian-tooley-racing-truck-norris-nsr-camshaft-no-springs-required) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-16*
