【Premium Material】The tensioner cover plate is made of raw 6061 billet aluminum alloy with anti-rust and anti-corrosion function. It is durable and can prolong the service life of the product.
【Function】The tensioner cover plate is designed with a simple o-ring seal that is set into a machined groove on the back of the cover. This o-ring seal design makes timing chain tensioner checks and changes much faster and easier because it completely eliminates the need for messy sealer which we all know is a pain to clean off.
