You are right, but not on our cars. One some cars, you can buy underdrive pulleys for the water pump, alternator, power steering pump..etc and still use the original stock crank/dampner pulley. On our cars they make one underdrive pulley that slows down all the accessories. This is the pulley pictured above. There is a company that makes a UDP with a vibration dampner built in it, but I don't remember the name. I do remember it was pretty expensive though.4u2nv said:I thought the Crank Pulley was the Harmonic Balancer and the Underdrive Pulleys were a totally different part.
For Example: I could buy the Crank Pulley and the Underdrive Pulleys and use them together, since they are a totally different part.
Damn am I confused....![]()
