Unleash the Beast: Complete Stage 3 Performance Camshaft Upgrade Kit for LS V8 Engines

Ready to wake up your LS engine and get that aggressive, head-turning "choppy" idle? Whether you are building a street/strip Camaro, upgrading a Corvette, or adding serious top-end power to your Silverado, this Stage 3 Performance Camshaft Upgrade Kit is engineered to deliver massive horsepower gains. Designed specifically for Gen 3 and early Gen 4 LS-based engines, this premium package aggressively alters your valve timing to provide razor-sharp throttle response and maximum high-RPM performance that will completely transform your vehicle's driving dynamics.

Upgrading to a high-lift cam requires beefing up the entire valvetrain to prevent failure, and this master package provides the essential reinforced components you need. At its core is our specialized Stage 3 Performance Camshaft (Specs: 238/242 @.050", .595"/.595" Lift, 112 LSA). To safely handle this intense .595" lift without valve float, the bundle comes fully loaded with 16x PAC-1218 beehive valve springs, 16x heavy-duty 7.400" chromoly pushrods, and 16x HL2148S hydraulic roller lifters with trays. To ensure your high-horsepower build stays reliably lubricated and precisely timed, we also include a high-volume M295 oil pump, a durable engine timing chain kit, and premium valve stem seals. (⚠️ Install Note: Custom ECU tuning is strongly recommended for optimal drivability and idle quality with this aggressive profile. Please note that cylinder head gaskets and head bolts are NOT included in this package.)

Engineered as the ultimate high-performance valvetrain solution for a massive range of GM V8 applications. This kit is perfectly compatible with 5.7L LS1/LS6, 6.0L LS2, and 4.8L/5.3L/6.0L LQ4/LM7 truck engines. It fits iconic muscle cars like the 1998-2002 Camaro SS/Firebird, 1997-2007 Corvette, and 2005-2006 GTO, as well as hard-working 1999-2007 Silverado/Sierra 1500-3500 trucks, Tahoe, Suburban, Yukon, and Escalade. Upgrade your LS valvetrain the right way with BTSCAR's premium performance components and dominate the street or track.
