Ok well pretty much what the title says. I had my waterpump pulley (aluminum) kinda explode and wanted to replace it again obviously but would like to use a steel underdrive on the waterpump since its the biggest weakest pulley. I dont want to have to buy a whole set of sn pulleys just for that one. So was wondering if I could just order a fox underdrive pulley set and use just the waterpump pulley. Since fox sets are cheaper, lol.
