Detailed Product Description
This Continental serpentine belt drive component kit (part number K49275B) is engineered to meet the demands of heavy-duty GM vehicles including the Cadillac Escalade, Chevrolet Avalanche 1500, and GMC Yukon XL 2500. The kit’s drive belt features six grooves and a length of 93 inches, designed to fit accessory drive systems requiring precise belt dimensions. The included steel idler pulley, with a smooth surface and dimensions of 3.54 inches in diameter and 1.19 inches in width, ensures consistent belt tracking and reduces friction. The tensioner maintains proper belt tension, preventing slippage and premature wear, which is critical for vehicles such as the Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD that operate under demanding conditions.
