Maximum Street Performance: Sloppy Stage 3 Camshaft & Valvetrain Overhaul Kit for GM LS V8
Are you ready to unlock massive power gains, crisp throttle response, and that unmistakable, aggressive "choppy" idle in your LS-powered project car or truck? Sourcing individual valvetrain upgrades for a high-performance camshaft swap can quickly lead to compatibility issues and frustrating technical delays. Take the guesswork out of your build and bulletproof your top-end with this Comprehensive Master Sloppy 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 reliable camshaft swap in a single service.
The centerpiece of this high-performance package is the legendary E1841P Sloppy Stage 3 Camshaft, delivering an aggressive .595" intake/exhaust lift with a 112° lobe separation angle designed to optimize top-end power across a wide 2200 to 5400 RPM range. To safely manage the demands of this aggressive lift profile, we have pre-matched and bundled industry-standard valvetrain upgrades: 16 high-strength PAC-1218 Beehive valve springs, 16 heavy-duty 7.400" pushrods, and 16 high-performance hydraulic roller lifters with fresh trays. To ensure a professional-grade, leak-free reassembly, this master kit also features a complete top-to-bottom sealing set, including premium Multi-Layer Steel (MLS) cylinder head gaskets, a timing cover gasket, a complete head bolt set, valve seals, and necessary cam 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.)
