This v-belt is an exact fit for the drive belt on my Husqvarna YTH22V46 riding mower/tractor. Being made with Kevlar, the exterior surface has a superior friction surface and engages fully with the driven pulley on the TuffTorq K46 hydostatic transmission. The OEM belt was beginning to wear and I was experiencing some reduced speed when mowing on upward slopes which I attributed correctly to belt wear. This belt does not slip and with the Kevalr cords the stretch will be minimal. This is a SUPERIOR product and when the blade belt needs replacing I will purchase from V-Belt guys. Furthermore, the price plus shipping was several dollars less than any other "standard" belts!
