High-RPM Power Unleashed: Premium Gen 3 & Gen 4 LS Stage 3 Camshaft & Valvetrain Upgrade Kit
Are you looking to unlock massive horsepower gains, crisp throttle response, and that iconic, aggressive "choppy" idle sound in your LS-powered street machine or truck? Sourcing individual valvetrain components for a high-performance camshaft swap can lead to compatibility issues and costly technical delays. Take the guesswork out of your build and upgrade your top-end with this Premium Stage 3 Camshaft Overhaul Kit. Specifically engineered for Gen 3 and Gen 4 LS-based 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L engines, this pre-matched package provides the essential heavy-duty internal components required to handle high-lift valvetrain stress in a single service.
The centerpiece of this performance package is the legendary E1841P Stage 3 Camshaft, delivering an aggressive .595" intake/exhaust lift with a 112° lobe separation angle (238/242 duration at .050") engineered for maximum high-RPM breathing and power delivery. To safely handle the demands of this high-lift profile without coil bind, the kit includes 16 high-strength PAC-1218 Beehive valve springs. It is paired with 16 heavy-duty 7.400" chromoly pushrods designed to resist flexing under intense valve lift conditions. For a reliable and leak-free reassembly, the kit is rounded out with premium valve stem seals, a front timing cover gasket, and necessary camshaft/crankshaft mounting hardware.
(⚠️ CRITICAL KIT CONFIGURATION NOTE: This listing includes the mechanical camshaft, valve springs, pushrods, seals, and timing cover gasket ONLY. It does NOT include hydraulic roller lifters or cylinder head gaskets, making it the perfect kit if you are doing a cam swap without removing the cylinder heads. Custom ECU recalibration / computer tuning is strictly required after installation to handle the aggressive duration. Professional installation and valvetrain geometry checking are highly recommended.)
Engineered to transform your daily driver, truck, or project car into a high-powered performer. This comprehensive upgrade kit flawlessly fits a massive selection of LS engines, including 1999-2013 Chevrolet Silverado and GMC Sierra trucks/SUVs (4.8L/5.3L/6.0L LQ4/LM7), 1998-2002 Camaro SS and Firebird Trans Am, 1997-2004 Corvette C5 (LS1/LS6), Gen IV 6.0L platforms like the TrailBlazer SS/GTO (LS2), and high-displacement 2008-2013 Corvette/Camaro platforms (6.2L LS3). Save time and modify your valvetrain the right way with BTSCAR's premium replacement components.
