The accessory belt drive tensioner automatically adjusts tension in the Micro-V® belt to ensure proper function and output of accessory components, dampens peak loads during engine acceleration and deceleration, and ensures your belts and engine perform when your vehicle needs them most. From casting quality to the design of internal components, we understand that every aspect of a tensioner is critical to long service life, which is why we've engineered our DriveAlign® tensioners to exceed some of the most rigorous quality and performance standards in the industry.

Features and Benefits

  • Manufactured using the same technology and quality materials as the Original Equipment Manufacturer (OEM) part, assuring a factory match.
  • Patented vibration damping system absorbs extreme vibration to improve tensioner as well as belt and accessory life.
  • Torsional round spring design provides consistent tension and does not allow contamination.


With a full line, Gates is proud to engineer automotive solutions with some of the most comprehensive coverage in the industry. We manufacture our tensioners to meet or exceed OE specifications to ensure precise fit, exceptional performance, and maximum durability for virtually every vehicle on the road today.
