Installed on Saabaru Aero 2.0 2005. Easy installation was stronger than Subaru stock plastic pulley and smoother. I changed the straps to Gator V as we will do. There was some noise before installation, not with the new mechanism. If anything changes, we will let you know. Hence 5 stars for something that seems better than the standard. I have driven 5000km since installation and everything is fine.
