By design, this particular flap will need to be replaced every so often as the flaps take a major beating while riding.  We do sell replacement flaps as a set for $50 if you just need the mud flaps and $60 if you need the hardware kit. You can also purchase replacement lower flaps for the front fender extensions. Those prices include shipping to the Continental United States. Shipping to Alaska, Hawaii, Puerto Rico and International orders is more.  You can find the page on our website here: Replacement Flaps
