ACDelco V-Ribbed Serpentine Belts

ACDelco V-ribbed serpentine belts resist the penetration of water, acids, and ozone--plus, they provide broad temperature tolerances. Their patented advanced technology design incorporates EPDM rubber, which stays soft and pliable longer than traditional belt materials. Neoprene and certain grades of rubber can harden, causing unwanted squealing and a shorter belt life. The flexible construction of these serpentines allows each belt to withstand many topside and backside bends. ACDelco offers their V-ribbed replacement belts in various lengths, widths, and rib quantities for a wide range of fitments.
