Designed specifically for Gen 3 and early Gen 4 LS-based engines, this comprehensive package aggressively alters your valve timing to provide razor-sharp throttle response and unmatched high-speed performance.

To safely handle this intense .595" lift and prevent 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 absolute reliability and a perfect seal under extreme cylinder pressures, we've also included premium Multiple Layers Steel (MLS) head gaskets, a complete cylinder head bolt set, a high-volume M295 oil pump, and a durable engine timing chain kit. (⚠️ Install Note: Due to the extremely aggressive nature of this Stage 3 profile, an upgraded high-stall torque converter (3000+ stall) and professional custom ECU tuning are REQUIRED for optimal performance and drivability.)
Engineered as the definitive high-performance solution for a massive range of GM V8 applications. This master kit is perfectly compatible with 5.7L LS1/LS6, 6.0L LS2, and 4.8L/5.3L/6.0L LQ4/LM7 truck engines.
