Maximum Street Performance: Ultimate Master LS Stage 3 Camshaft & Valvetrain 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? Sourcing individual valvetrain, timing, and sealing components for a high-performance camshaft swap is not only time-consuming but can lead to devastating compatibility issues. Eliminate the guesswork and bulletproof your entire top-end and front-end engine assembly with this Ultimate Master 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 all-in-one overhaul package provides every premium component required to handle heavy lift stress and execute a complete, reliable camshaft swap in a single service.
The centerpiece of this ultimate performance package is the legendary E1841P Stage 3 Camshaft, delivering an aggressive .595" intake/exhaust lift with a 112° lobe separation angle designed for maximum high-RPM power delivery. To safely manage the demands of this aggressive lift profile, we have bundled industry-standard valvetrain upgrades: 16 high-strength PAC-1218 Beehive valve springs, 16 heavy-duty 7.400" pushrods, and 16 premium HL2148S hydraulic roller lifters (with fresh trays).
Going far beyond a basic valvetrain kit, this master set ensures your engine's internal health by including a brand-new high-volume oil pump and a complete engine timing chain kit. To guarantee a professional-grade, leak-free reassembly, you also receive a full top-to-bottom sealing and hardware set: premium Multi-Layer Steel (MLS) cylinder head gaskets, a complete cylinder head bolts set, a timing cover gasket with overhaul seals, premium valve stem seals, and your essential crankshaft/camshaft mounting hardware.
Camshaft Profile Specifications:
RPM Range: 2200 to 5400 RPM
Intake / Exhaust Valve Lift: .595" / .595"
Duration at .050": 238° Intake / 242° Exhaust (Advertised: 296° / 299°)

Cam Gear Attachment: Strong 3-Bolt Design
(⚠️ CRITICAL INSTALLATION NOTE: This master kit features a 3-bolt camshaft gear attachment. Custom ECU recalibration / computer tuning is strictly required after installation to handle the aggressive duration and ensure proper drivability. Due to the high-performance specifications and the requirement of cylinder head removal for lifter replacement, professional valvetrain geometry checking and installation are highly recommended.)
Engineered to transform your daily driver, classic truck, or race car into a high-powered machine. This comprehensive ultimate 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.
