Check Vehicle Fit

CARQUEST by Dayco® Automatic Belt Tensioners are specifically built to outperform and outlast competitive OE parts. The heavy duty cast aluminum spring case resists cracking and fatigue. Each component is built to resist rust, endure the toughest of conditions while promoting quieter performance and longer life.

Product Features:
  • Manufactured with a specially coated patented flat wire spring to allow the internal tension to be concentric, thus providing a more even degree of constant tension
  • The patented Deflected Arm Plate dampens arm movement, prolonging the life of the tensioner by limiting the amount of rotational movement
  • Contains a metallic locator pin built to withstand extreme drive demands and properly locate the tensioner for installation
  • Dayco's patented Nylon Pivot Bushing keeps internal components in constant contact to maintain proper tensioner alignment
