Maximum Street Performance: Premium LS Stage 3 Camshaft, Lifters & Head Gasket Overhaul Kit
Are you ready to unlock massive horsepower gains, crisp throttle response, and that unmistakable, aggressive "choppy" idle in your LS-powered project car or truck? Performing a high-performance camshaft swap requires meticulous attention to your valvetrain and engine sealing components. Eliminate the guesswork and bulletproof your top-end rebuild with this Premium Stage 3 Camshaft and Valvetrain Kit. Specifically engineered for Gen 3 and Gen 4 LS-based 4.8L, 5.3L, 5.7L, and 6.0L engines, this overhaul package provides the essential premium components required to safely handle heavy lift stress and execute a reliable cam and lifter swap 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 designed to maximize high-RPM breathing and power delivery. To support this aggressive profile, we have included 16 heavy-duty 7.400" pushrods and 16 premium HL2148S hydraulic roller lifters (complete with fresh lifter trays). Because replacing lifters on an LS engine requires removing the cylinder heads, this kit conveniently includes a complete top-end sealing solution: premium Multi-Layer Steel (MLS) cylinder head gaskets, a complete cylinder head bolts set, a timing cover gasket with overhaul seals, valve stem seals, and a camshaft/crankshaft mounting bolt.
Camshaft Profile Specifications:
RPM Range: 2200 to 5400 RPM
Intake / Exhaust Valve Lift: .595" / .595"
Duration at .050": 238° Intake / 242° Exhaust
Lobe Separation / Intake Centerline: 112° / 108°
Cam Gear Attachment: Strong 3-Bolt Design
(⚠️ CRITICAL KIT CONFIGURATION NOTE: This listing includes the mechanical camshaft, lifters, pushrods, and complete head gasket sealing kit ONLY. It DOES NOT include upgraded valve springs (such as PAC-1218). You must source proper high-lift beehive or dual valve springs separately to prevent coil bind with this .595" lift profile. Custom ECU recalibration / computer tuning is strictly required after installation. Professional installation is highly recommended.)
Engineered to transform your daily driver, classic truck, or street/strip car into a high-powered machine. This comprehensive upgrade kit flawlessly fits a massive lineup of LS platforms, including 1999-2007 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), and Gen IV LS2 6.0L engines found in the TrailBlazer and Pontiac GTO. Modify your valvetrain the right way with BTSCAR's premium replacement components and build with total confidence.
