Maximum Street Performance: Ultimate Master LS Sloppy Stage 2 Camshaft & Engine Overhaul Kit
Are you ready to unlock massive mid-to-high RPM power gains, crisp throttle response, and that legendary, aggressive "choppy" idle sound in your LS-powered street machine or truck? Sourcing individual valvetrain, timing, and sealing components for a high-performance camshaft swap can be a frustrating, time-consuming process that often leads to missing parts and installation delays. Eliminate the guesswork and bulletproof your engine's entire top-end and front-end with this Ultimate Master Sloppy Stage 2 Camshaft and Overhaul Kit. Specifically engineered for Gen 3 and Gen 4 LS-based 4.8L, 5.3L, 5.7L, and 6.0L engines, this comprehensive package is the definitive all-in-one solution for enthusiasts looking to maximize performance and reliability in a single service.
At the heart of this master rebuild set is the highly renowned E1840P Sloppy Stage 2 Camshaft, delivering an aggressive .585" intake/exhaust lift designed to optimize power delivery and mid-range torque. To safely handle the demands of this high-lift profile without 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).
Going far beyond a basic valvetrain upgrade, this ultimate kit ensures your engine's internal health and precise synchronization by including a brand-new M295 high-volume oil pump and a complete engine timing chain kit. Because replacing the lifters requires removing the cylinder heads, you also receive a complete top-end sealing and hardware solution: premium Multi-Layer Steel (MLS) cylinder head gaskets, a complete set of cylinder head bolts, a timing cover gasket with a front seal, valve stem seals, and your essential crankshaft/camshaft retainer bolt.

(⚠️ CRITICAL KIT CONFIGURATION & INSTALLATION NOTE: This master kit features a 3-bolt camshaft gear attachment. An upgraded torque converter (2500+ stall) and custom ECU recalibration/tuning are strongly recommended for optimal performance and drivability with this Stage 2 profile. 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 classic truck, SUV, or muscle car into a high-powered street performer. 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 early Gen IV LS2 6.0L applications like the TrailBlazer SS and Pontiac GTO.
