Has anyone crossed this belt to a more affordable belt? Why is this belt $90

Yes it crosses to 18-15115 which is $80. I can buy 2 serpentine belts for boths cars for less! Not complaining about the price just looking to see if anyone used a different belt.

A metric serpentine has a part number by number of ribs, a PK then length in MM. I think yours is a 6 rib serpentine and 2471 mm (97.2 inches).
