Maximum Street Performance: Premium LS Sloppy Stage 2 Camshaft & Valvetrain Upgrade 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 components for a high-performance camshaft swap can be a frustrating, time-consuming process that often leads to missing parts and installation delays. Take the guesswork out of your build and upgrade your engine's front-end with this Premium Sloppy Stage 2 Camshaft and Valvetrain Kit. Specifically engineered for Gen 3 and Gen 4 LS-based 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L engines, this pre-matched package provides the essential heavy-duty internal components required to safely handle high-lift valvetrain stress while transforming your engine's overall performance.

At the heart of this performance package 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 coil bind or valve float, we have bundled industry-standard valvetrain upgrades: 16 high-strength PAC-1218 Beehive valve springs and 16 heavy-duty 7.400" chromoly pushrods designed to resist flexing under intense valve events. For a reliable and leak-free reassembly, the kit is rounded out with premium valve stem seals, a front timing cover gasket with a front seal, and a heavy-duty camshaft retainer bolt.

Camshaft Profile Specifications:
RPM Range: 2200 to 5400 RPM
Intake / Exhaust Valve Lift: .585" / .585"
Duration at .050": 228° Intake / 230° Exhaust
Lobe Separation (LSA): 112°
Cam Gear Attachment: Strong 3-Bolt Design

(⚠️ CRITICAL KIT CONFIGURATION & INSTALLATION NOTE: This listing includes the mechanical camshaft, valve springs, pushrods, seals, and timing cover gasket ONLY. It DOES NOT include hydraulic roller lifters or cylinder head gaskets, making it the perfect upgrade kit if you are performing a cam swap without removing the cylinder heads. An upgraded torque converter (2500+ stall) and custom ECU recalibration/tuning are strongly recommended for optimal performance and drivability with this Stage 2 profile. Professional installation is highly recommended.)

Engineered to transform your classic truck, SUV, or muscle car into a high-powered street performer. This comprehensive upgrade kit flawlessly fits a massive lineup of LS platforms, including 1999-2013 Chevrolet Silverado and GMC Sierra trucks/SUVs (4.8L/5.3L/6.0L LQ4/LM7), 1998-2002 Camaro SS and Firebird Trans Am, Corvette C5/C6 (LS1/LS2/LS3), and Gen IV 6.2L Camaro platforms.
