Say goodbye to fuel mileage lol ### ⭐⭐⭐⭐⭐ GREAT CAM *by N***R on January 5, 2026* Great cam. I must have for your LS engine. 5 star rating for the BTR TRUCK NORRIS NSR CAM. ### ⭐⭐⭐⭐⭐ Good chop, reliable valvetrain *by K***A on February 7, 2025* 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 ## 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.vn/products/515728346-btr-brian-tooley-racing-truck-norris-nsr-camshaft-no-springs](https://www.desertcart.vn/products/515728346-btr-brian-tooley-racing-truck-norris-nsr-camshaft-no-springs) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-15*
