Heavy-Duty Accessory Belt Drive System

The Longest Lasting Belt Tensioners in the Industry

Engineered to exceed demanding OEM requirements.  In laboratory tests, under extreme peak-to-peak vibration and contamination tests, DriveAlign^® heavy-duty tensioners lasted up to three times longer than competitive aftermarket tensioners.

Labyrinth Seal – prevents contamination of internal parts for maximum durability and service life Machined Steel Pulley – reduces surface wear while shielding internal bearing from outside contaminants Double Row Bearings – twin rows of bearings carry more load and last up to three times longer than two individual bearings Optimised Components – engineered for maximum strength and durability Patented Design – provides superior belt alignment and tension for improved drive efficiency and life Round Spring Wire – includes chrome-silicone torsion spring for less flex-fatigue than flat-wire designs Patented Damping Mechanism – provides maximum stability, reducing vibration and increasing the life of belt, tensioner and other accessory drive components
