Accessory Belt Drive Kit for Silverado HD

Restore the front-end accessory drive on a 2001 Chevrolet Silverado 2500 HD or Silverado 3500 with the Gates Accessory Belt Drive Kit 90K-38136A. This serpentine belt drive component kit is built around the belt, tensioner, and idler pulley needed to service the complete drive system in one repair.

For 2001 Chevrolet Silverado 2500 HD and Silverado 3500 applications with dual 105A alternators, this kit helps address wear across the belt drive system instead of replacing only the belt.
