What is it? This is a tensioner from GM, factory part number 84937708. It is catalogued under Belts & Pulleys > Pulleys & Tensioners.
Where does it fit? Mounting position is left and front.
Which versions are covered? Build notes: Tahoe and Suburban.
Anything to check first? Pulley alignment matters as much as pulley condition, and a tensioner that sits a millimetre out of plane will wear one edge of the belt. Confirm the number before you order, because a near match will bolt on and still be wrong. Send the VIN if the old marking has gone.
How fast does it ship? In stock and sent from the US in one to two business days, free delivery over $59.
