WARNING: The only way to install the a 2.60" Pulley is to have the Snout Housing Machined down for it to fit properly. Some Snout Housing Castings are made differently in sizes and do vary, as to what the smallest pulley you can use without machining. The smallest size we recommend is 2.75", without any machining performed on the snout housing casting area.
NOTICE: Installation and Removal of the Stock pulley over to our New Pulley will require a Power Steering Puller Tool for use on this pulley application. You DO NOT want to use any Aftermarket Puller Tool, as it will not work properly and will Ruin the stock pulley on removal. This Removal Technique is only for the Magnacharger Keyed Style Supercharger Pulleys applications ONLY! 8 Rib Pulley Applications are Custom Order Only!
