Maximum Street Performance: Premium LS Stage 3 Camshaft & Top-End Overhaul Kit
Are you ready to unlock massive high-RPM horsepower, blistering throttle response, and that extremely aggressive, "choppy" idle sound in your LS-powered street machine or truck? Sourcing individual valvetrain and sealing components for a high-performance camshaft swap can be a frustrating and time-consuming process that often leads to missing parts and costly installation delays. Eliminate the guesswork and bulletproof your engine's top-end with this Premium Stage 3 Camshaft and Valvetrain 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 comprehensive package is the ultimate foundation for enthusiasts seeking maximum power output and reliability in a single service.
At the heart of this high-performance set is the renowned E1841P Stage 3 Camshaft, delivering a massive .595" intake/exhaust lift designed to optimize high-RPM breathing and power delivery. To safely handle the extreme demands of this aggressive lift profile without coil bind or valve float, we have bundled industry-standard valvetrain upgrades: 16 high-strength PAC-1218 Beehive valve springs, 16 heavy-duty 7.400" chromoly pushrods, and 16 premium HL2148S hydraulic roller lifters (complete with fresh lifter trays). Because replacing the lifters on an LS engine requires the removal of the cylinder heads, this kit conveniently provides an essential top-end sealing solution, including premium Multiple Layers Steel (MLS) cylinder head gaskets, a timing cover gasket with a front seal, valve stem seals, and your essential crankshaft/camshaft retainer bolt.
Camshaft Profile Specifications:
Intake / Exhaust Valve Lift: .595" / .595"
Duration at .050": 238° Intake / 242° Exhaust
Lobe Separation (LSA): 112°

(⚠️ CRITICAL KIT CONFIGURATION & INSTALLATION NOTE: This listing includes the mechanical camshaft, valvetrain components, and MLS head gaskets ONLY. It DOES NOT include cylinder head bolts, which are torque-to-yield and MUST be purchased separately to complete your cylinder head installation. Additionally, an upgraded high-stall torque converter (3000+ stall) and professional custom ECU tuning are REQUIRED for optimal performance and drivability with this aggressive Stage 3 profile. Professional installation is highly recommended.)
Engineered to transform your daily driver, track car, or custom truck into a high-powered street performer. This comprehensive upgrade kit flawlessly fits a massive lineup of LS platforms, 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, Corvette C5/C6 (LS1/LS2/LS3), and Gen IV 6.2L Camaro platforms.
