      These pullies are pretty good

      I was surprised at the sr underdrive pullies and how much of a power difference they made. BUT at idle at night time your headlights will be very dim, and blower fan will slow down, due to not having as much alternator output. Soon as you get going again it goes back to normal. I would say if you dont mind that I would go for it. There's a price to be paid for performance gains. They did not take me more than an hour or so to install, but I have an electric ratchet as well.

      SR Performance Underdrive Pulleys

      I bought these to replace the BBK pulleys that were previously on the engine due to the water pump pulley having heavy wear and glazing the belt. So far, the black power coating is doing it's job and not flaking off. So far very satisfied.

      Decently easy to install would 100 recommend using a impact for the bolts you can reach or it will turn a 1hr job into a 4hr one haha. Overall very satisfied with the product.

      Response is quicker for sure.

      Had these for a while and finally installed them today. Pros are, better throttle response, Rpms climb quicker, the power is delivered right away which makes you feel more connected to the car and the OEM belt does fit perfectly. Cons are the voltage gauge will drop a lot when you come to a stop due the alternator not spinning as fast, but it doesn't cause any problems though and the directions say you can do this job with hand tools which is not true about the alternator pulley. You will need a impact gun for the alternator pulley. I removed the whole alternator and took it to Pepboys to remove and install the new pulley for free in less then five minutes. All being said, definitely was worth the money.

      Great value and a good price..

      The product was a direct bolt on, that gave under my hood a fresh look and a slight power gain but most importantly had know effects on the operating temperature of my car.

    Can I just use the crank pulley?

    • Technically, you can use just the crank pulley from this kit but is ideal to install all pulleys in this kit to ensure the proper mounting alignment of the belt is met.
