Product Line Details

Gates Premium OE Stretch Fit Micro-V Belts are made for unique stretch-fit drive systems where belt length and installation method matter.

Verify whether the vehicle is equipped with or without a tensioner before ordering, especially on the listed Ford Escape, Ford Taurus, Mazda Tribute, and Mercury Sable applications.
