Key Features
- Gates DriveAlign Premium OE Automatic Belt Tensioner
- Part number 39408
- OE Exact grade for original-equipment-style replacement
- Thermoplastic housing for accessory drive belt system service
- Single pulley design with smooth/backside belt contact
- V-ribbed belt type application

Product Details
Gates draws on original equipment system design experience to produce premium DriveAlign automatic belt tensioners that follow rigid manufacturing tolerances. This helps maintain OE fit and consistent belt tracking in accessory drive belt systems. The 39408 tensioner assembly is specified with one pulley, no flange on pulley 1, and a smooth/backside contact surface, making it a direct-match style component for vehicles that use a V-ribbed belt layout.
This part cross-references Chrysler 5281573AB for the same application. If you are replacing a worn Gates 39408 unit on a Chrysler vehicle, matching the OE Exact specification helps keep the accessory drive system aligned to factory requirements.
What This Part Helps Address
- Belt squeal caused by weak or inconsistent tension
- Accessory belt flutter or vibration
- Uneven belt wear from a worn pulley or bearing
- Loss of proper belt tracking in the drive system
- Noise from a failing automatic tensioner assembly
Installation Notes and Tips
Verify belt routing, pulley alignment, and mounting-hole location before installation. Inspect the accessory drive belt, idler pulleys, and related components for wear at the same time, since a new tensioner works best with a belt in good condition. Confirm vehicle application by part number and OE reference before ordering, especially for Chrysler models that use the 39408 tensioner assembly.
Compatible With Chrysler vehicle applications that specify Gates 39408 or OE reference 5281573AB. For Chrysler repair work, use the OE-style dimensions and pulley profile to confirm the correct replacement before installation.
Quality Assurance
Gates is an OE system design supplier, and the DriveAlign Premium OE Automatic Belt Tensioner line is manufactured to rigid tolerances and specifications to support OE fit, form, and function. That focus on original-equipment-style construction is central to the 39408 tensioner assembly.
