The Gates tensioner assembly for 2003–2007 GMC C5500 with the 8.1L V-8 is a vehicle-specific replacement for the accessory belt drive. It maintains proper serpentine belt tension and routing to support reliable operation of driven accessories and helps address belt noise or slippage that can occur when the original tensioner is worn.
