6 Rib Magnuson Magnacharger TVS2300 / TVS1900 Supercharger Pulley

These are a 6-rib design. If you need idlers I make these as well. If you'd like to upgrade to an 8 or 10 rib system and have a crankshaft pulley I can make you idler pulleys. These pulleys will allow you much more adjustability in your boost level.
