However, springs can only flex so many times before they fail. PolyForce Belt Tensioners replace this spring with a New and unique Polymer Torsion Core A longer lasting compressed polymer replaces the spring, thereby eliminating the primary cause of failure. The Polymer Torsion Core also doubles as a built-in damper, reducing stress on adjacent accessories without additional damage to the belt tensioner. TENSIONERS REINVENTED!
