THESE ARE ALL J10 BELTS Balmar Altmount kits already come with one spare belt, if you want to order more this is the place. They can be a bit hard to source so it is recommended to carry a few if you are planning a long trip. This is an extra wide 10 rib serpentine belt. See the list below to check your belt size, note that AT-200 alternators will most likely need longer than the standard.
Tech TipIf you are ordering a new pulley kit it would be best to wait and see if the belt that comes with it fits before ordering additional belts. Each kit already comes with a spare.
