Product Description


Please note: These are no longer being manufactured in aluminum finish, but are black powdercoated instead. The photos above are no longer accurate.

If you like to swap your supercharger pulleys occasionally or often, we have the solution for you. Featuring the finest engineering, materials and workmanship available, the Qwikchange Pulley System allows the quick and easy swap of your supercharger pulley with a wide range of pulley sizes available.

There is not a better solution available. Featuring the lightest hub assembly available, the Qwikchange Pulley System hub weighs in at a slender 5.6 ounces! Made from 15-5 PH (15Cr-5Ni), a martensitic precipitation hardening chromium-nickel stainless steel offering high strength and hardness along with excellent corrosion resistance. 15-5 is used for applications requiring high transverse strength and toughness, such as valve parts, fittings, fasteners, shafts, gears, engine parts, aircraft and nuclear reactor components. The hub comes with 18-8 Stainless Steel screws and ball end hex wrench.

The 6061 T6 aluminum pulley is precision machined to ANSI/RMA dimensional specifications for the best belt grip. The pulleys feature countersunk screw holes for even lighter weight (a 3.4" pulley weighs in at 3.5 ounces). Having the screw holes countersunk also keeps the rotational mass of the screws inside the belt area for better balance. Finally the pulleys are clear anodized for protection and to keep them looking great.

You will need a proper puller tool to remove your current supercharger pulley and install the hub of the Qwikchange Pulley System. The Supercharger Pulley Removal/Installation Tool is available by clicking the Related Products link to the right.

The hub is engineered to accommodate pulleys as small as 2.4".

The Qwikchange Pulley System includes one hub with screws and hex wrench and one pulley of your choice. Additional pulleys are available as well. Make your selection above.

Also fits 2004-2008 Grand Prix, 2004 Monte Carlo SS and 2004 Impala SS.

The hardest part about this system's installation is getting the original pulley off! We thoroughly destroyed two pulley removal tools supposedly designed just for this purpose before resorting to the torch. After cleaning and polishing the S/C shaft we froze it with liquid nitrogen. We quickly set and aligned the QuickChange adapter on the shaft and hit the whole setup with a heat gun. Presto! It wont be spinning off anytime soon. It works great and at a decent price you'd be saving yourself a lot of time and trouble by getting one if you are one who is constantly changing the S/C pulley.

The Qwikchange system is great, it has a high cost if you have to buy all the stuff to put it on like the puller and a new belt. But the horse power gains are incredible.

I recently purchased the Qwikchange System from PFYC. The order went out as promised, with no delays, and once it was installed on my car with the 3.2" pulley, the horsepower is incredible. Be sure to have a cold air intake if not an intercooler to get the best performance gains from this system.
