Ultimate Street Performance: Comprehensive Gen 3 LS Stage 2 Camshaft & Valvetrain Overhaul Kit
Are you ready to unlock massive horsepower gains, crisp throttle response, and that iconic, aggressive muscle-car idle in your Gen 3 LS engine? Sourcing individual valvetrain components for a high-performance camshaft swap can lead to compatibility headaches and costly missing-part delays. Eliminate the guesswork and bulletproof your internal assembly with this Comprehensive Master Stage 2 Camshaft and Valvetrain Kit. Specifically engineered for Gen 3 LS-series 4.8L, 5.3L, 5.7L, and 6.0L blocks, this all-in-one overhaul package delivers every premium component required to handle high-lift stress and perform a total top-end restoration in a single service.
The center of this high-performance package is the legendary E1840P Stage 2 Camshaft, delivering an aggressive .585" intake/exhaust lift with a 112° lobe separation angle that optimizes power across a broad 2200 to 5400 RPM range. To safely manage this aggressive lift, we have bundled industry-standard valvetrain upgrades: 16 high-strength PAC-1218 Beehive valve springs, 16 heavy-duty 7.400" chromoly pushrods, 16 premium LS7-style lifters with fresh guides, and a high-volume oil pump to ensure consistent oil pressure. Additionally, this kit provides a complete top-to-bottom sealing and mounting solution, including premium Multi-Layer Steel (MLS) cylinder head gaskets, a complete 30-piece head bolt set, a timing cover and water pump gasket set, a heavy-duty timing chain, and necessary hardware.

Always verify your engine block generation and specs before purchasing.)
