Wake Up Your LS: Complete Gen 3 & Gen 4 Stage 3 Camshaft & Valvetrain Master 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 restrictive, holding back the true horsepower and torque potential of your highly capable Gen 3 and Gen 4 platform. If you want to dominate the track and the street, a serious valvetrain upgrade is the ultimate way to transform your vehicle's attitude. Unlock massive power gains, significantly improved throttle response, and that unmistakable, aggressive "choppy" idle with our complete Stage 3 Camshaft Upgrade Master Kit.

Unlike a basic bare camshaft swap that risks valve float or oil starvation, this high-performance master package provides all the critical valvetrain and oil delivery components needed to handle increased lift reliably. The centerpiece is the E1841P Stage 3 Camshaft (featuring an aggressive .595" lift profile), perfectly paired with a full set of genuine PAC-1218 beehive valve springs, heavy-duty 7.400" pushrods, and premium HL2148S hydraulic roller lifters. To guarantee bulletproof reliability during high-RPM pulls, this kit goes the extra mile by including a brand-new M295 high-volume oil pump, a complete engine timing chain kit, and high-quality valve seals. (⚠️ Fitment Note: Custom ECU tuning is strongly recommended after installation to ensure optimal drivability, smooth idle transitions, and to fully capitalize on these massive performance gains.)

Engineered specifically as a high-performance upgrade for a massive range of Gen 3 and Gen 4 LS-based V8 engines (4.8L, 5.3L, 5.7L, and 6.0L). This master kit is the ultimate bolt-on solution for the LS1, LS6, and LS2 found in the 1998-2002 Chevrolet Camaro / Pontiac Firebird and 1997-2007 Corvette, as well as the LQ4 and LM7 truck platforms powering the 1999-2007 Chevrolet Silverado / GMC Sierra 1500-3500, Suburban, Tahoe, and Cadillac Escalade. Don't leave horsepower on the table or risk your engine by reusing weak factory components. Upgrade your LS the right way with BTSCAR's premium-grade performance parts for head-turning sound and reliable, street-dominating power.
