Description
The Katech’s billet adjustable belt tensioner is a must. In LS engines, above certain RPM’s the stock tensioner will throw the serpentine accessory belt off the pulley. After observing this in their race engines, Katech’s engineers developed this tensioner and completely eliminated the issue. Pulley included.
Please note: Not recommend for use on supercharged engines unless the supercharger has a dedicated drive.
