Is is possible for you to offer a kit like your UR style kit (But obviously without the PS pulley) with this Main pulley?

Sorry, we can't offer that as an option. We would have to charge more for a 3 pulley kit than the 4 pulley kit since we would have to break up the UR Style pulley kits and have a bunch of random PS and main pulleys left over.

Individuals could buy both products and sell off the unused pulleys to recover costs. We have priced it so inexpensive in comparison to other main pulleys on the market that this is certainly an option.

What belt needs to be used with it ?? Depends on the pulley configuration.

Should I still use the Air Pump removal dummmy pulley ?? If your air pump is removed and idler should be installed.

What´s the benefit of an smaller diameter pulley ?? Underdrive

We worked out an agreement with our UR style pulley supplier to sell us the stock diameter billet Alternator and Water pump pulleys, so we now have a three piece billet single belt kit available.

Introductory price is $125.00, for the people that bought the main pulley by itself that would like the other two, just send Elaine an email.

It is highly recommended that an idler be installed with the kit.

Here is a pic the Banzai Single Belt Pulley Kit with the PR "BT" (big turbo) idler pulley. My records show 34.5" belt was chosen and is the perfect length for this combo..
