Detailed Description

Gates Accessory Belt Drive Kit 90K-38103B is a serpentine belt drive component kit for restoring the accessory belt system on select Chevrolet and GMC applications. The kit centers on the K060960 belt and matching tensioner and idler pulley components to help maintain proper belt tension and pulley alignment across the drive system. This approach supports a more complete repair on vehicles such as the Chevrolet Silverado 1500 and GMC Sierra 1500, especially when the original belt drive components show wear together.

This part cross-references Litens LV999010C for the same application.

What It Helps Address

  • Squealing or chirping from a worn serpentine belt
  • Loss of belt tension from a fatigued tensioner
  • Pulley noise caused by worn idler components
  • Uneven belt wear from aging accessory drive parts
  • Repeat repairs when only the belt is replaced

This kit is listed for W/A.C. applications and specific alternator configurations on select Chevrolet Express 1500, GMC Savana 1500, Chevrolet Silverado 1500, and GMC Sierra 1500 models. Use the vehicle notes to confirm the correct application before service, and compare the existing belt length and pulley layout to the listed specifications.
