RADIX Supercharger Pulleys for Magnuson Radix Superchargers

For the Magnuson Radix -- our custom designed SuperCharger pulley is light, as strong and a tight fit. All are black anodized.

Machined from an alloy bar stock, this is our own design. Thicker hub, dimension between hub and pulley grooves is double the thickness of our competitors. Stock supplied Magnuson pulley is 3.1" for 6.0L and 3.4" for 5.3L Truck. Note shaft size when ordering. We chose our aluminum alloy for weight, deflection (none) and wear properties -- as well as heat dissipation characteristics. This pulley has a lifetime warranty.

3.0", 2.9", and a radical 2.8" for higher boost at lower RPM. Do NOT order a 3.0", 2.9", or 2.8" without proper PCM programming.

Check belt tension after installation. Lower boost with smaller pulley often indicates a slipping belt!!
