I do not have anything against the product. When I made the purchase I was especting to get a three piece kit and I only got one (the engine shaft pulley), I contacted your customer service but I pressume it is in India so they could no help much except they gave me the manufacturer phone number. I already installed the pulley and this will be the last time I purchase something from your site. Alfredo Correa

Good product but needs clearer description.

Kudos to JET, my power steering is 40-50% more responsive and when taking sharp turns it doesn’t not bog down the motor, it feels like a new car. I did bypas the ac with a shorter belt, although I would think the ac would not kill the power as badly with this pulley. It is a one piece item. Do not expect a three piece set as the photo indicates pricey but worth it. Easy install.
