Michigan Motorsports' Truck Camshaft lineup is built for performance, reliability, and value. Each camshaft features lobe profiles designed to work with LS6-style beehive valve springs (.550" lift), allowing the use of factory retainers and locks for a simple and cost-effective upgrade. With moderate spring pressures and carefully engineered lobe profiles, these cams are easy on valvetrain components, making them a great choice for high-mileage street-driven trucks.
