VACP is improving on a classic. Our alt/gen Pulley Wrench has a 30mm hex wrench built in making it double as a crank pulley nut wrench as well as a handy bottle opener for when the job is done! Our accessory alt/Gen Nut Wrench is the perfect companion sporting 17, 19, 21 and 36 mm hex cuts which fit most stock and aftermarket alt/gen pulley nuts. These are perfect for your travel kit to help with that roadside belt replacement or valve adjustment. Buy both and save!
