The BTR Stage 2 LS Truck Camshaft V3 Cathedral-Port Kit is engineered to deliver stronger torque output, improved midrange power, and enhanced throttle response in cathedral-port LS truck engines. Designed by Brian Tooley Racing, this Stage 2 camshaft uses V3 lobe technology to balance performance and drivability, making it ideal for daily drivers, towing vehicles, and mild performance builds alike. With refined valve timing events and optimized lift profiles, this kit helps unlock additional torque without compromising low-end manners, idle quality, or vacuum. Builders can choose the Stage 2 cam as a direct performance upgrade or in conjunction with optional matched valvetrain components engineered by BTR to ensure proper valve control and long-term durability.
