No Springs AttachedConventional belt tensioners use springs to hold their position and tension. 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.

Improved BearingsPulley bearing absorbs a huge amount of vibration and can often fail too soon. To extend bearing life, PolyForce tensioners feature heavy-duty bearing that have a 40% higher load rating than the OEM and feature Anti-Vibration Grease, which won’t separate.

Misaligned

Alignment - Wider is BetterMisaligned belt tensioners lead to damaged tensioners, belts & accessories. A worn pivot bushing is typically the culprit of misalignment. PolyForce pivot bushings have a much wider stance, giving them drastically increased stability.
