Wake Up Your LS: Complete Gen 3 & Gen 4 Sloppy Stage 2 Camshaft & Valvetrain Kit
Is your LS build suffering from a tame factory exhaust note and choked mid-to-upper RPM performance? The factory LS camshaft is notoriously mild, limiting the true horsepower and torque potential of the otherwise incredibly capable Gen 3 and Gen 4 platforms. Upgrading your cam is the ultimate way to transform your vehicle's attitude. Unlock massive power gains, significantly improved throttle response, and that head-turning, aggressive "choppy" idle with our complete Sloppy Stage 2 Camshaft Upgrade Kit.
Unlike a bare camshaft swap, this high-performance package provides the critical valvetrain components needed to handle increased lift reliably. The centerpiece is the legendary E1840P Sloppy Stage 2 Camshaft, featuring a 3-bolt gear attachment, .585" intake/exhaust lift, 228°/230° duration at .050", and a 112° Lobe Separation Angle (LSA) for a massive powerband between 2200 and 5400 RPM. To prevent valve float and ensure valvetrain stability, this kit includes genuine PAC-1218 beehive springs, heavy-duty 7.400" pushrods, high-quality valve seals, a front timing cover gasket, and a new camshaft bolt. (⚠️ Fitment Note: This camshaft utilizes a 3-bolt gear attachment. Custom ECU tuning is strongly recommended after installation to ensure optimal drivability and to fully capitalize on the performance gains.)
Engineered specifically as a high-performance upgrade for a massive range of 1997-2013 Gen 3 and Gen 4 LS-based V8 engines (4.8L, 5.3L, 5.7L, 6.0L, and 6.2L). This master kit is the ultimate bolt-on solution for the LS1, LS6, LS2, and LS3 found in the 1998-2013 Chevrolet Camaro / Pontiac Firebird, 1997-2013 Corvette C5/C6, as well as the LQ4 and LM7 truck platforms found in the 1999-2013 Chevrolet Silverado / GMC Sierra 1500-3500, Suburban, and Tahoe. Don't leave horsepower on the table or risk your engine by reusing weak factory springs. Upgrade your LS the right way with BTSCAR's premium-grade performance parts for aggressive sound and reliable street-dominating power.
