The tensioner assembly was a great addition to my engine .It kept the belts tight and reduced wear and tear. The quality of the assembly is top-notch and it was easy to install. The only con i found was that the price was a little steep, but it was worth the investment for the added durability and performance. As an avid automotive enthusiast, I highly recommend this tensioner assembly for anyone looking to improve the performance and longevity of their engine..
