2003LSR (All Truck AND SUV)1

The Magnuson TVS1900 Radix Supercharger System is designed to unleash the potential of 2003 GM Trucks and SUVs with 4.8L, 5.3L, and 6.0L V8 engines. This bolt-on supercharger delivers approximately 120 horsepower and 120 foot-pounds of torque at the rear wheels, with around 6 psi of boost.

It features an integrated liquid-to-air intercooler with a front-mounted heat exchanger and electric water pump to keep intake air temperatures low, typically only 20-40 degrees Fahrenheit above ambient. An integrated bypass valve allows rotors to free-spin under light loads, minimizing parasitic loss and maintaining stock-like drivability and fuel economy.
