(⚠️ IMPORTANT INSTALLATION WARNING: This is a mid-level kit. Upgraded Valve Springs (e.g., PAC-1218) and Heavy-Duty Pushrods are NOT included but are STRICTLY REQUIRED to safely handle this intense .595" lift and prevent catastrophic engine damage. Additionally, due to the aggressive nature of this Stage 3 profile, an upgraded high-stall torque converter and professional custom ECU tuning are REQUIRED for optimal performance and drivability.)
