Tensioner for BMW Z Series E85/6 (2003-2008)

Clear BMW chassis

Please ensure your correct model is selected

The belt tensioner is responsible for keeping proper tension on the belt at all times and during all running conditions. When the tensioner ages, it loses some of the spring tension and can allow the belt to slip if left unchecked. Turner Motorsport carries Genuine BMW and high quality aftermarket options to get you back on the road in no time.
