Improve your rig with the 18?inch 10G 304 Stainless Steel Anti?Sail Mud Flap Plates which are heavy?duty accessories made in the USA to help keep mud flaps stable at highway speeds by resisting "sailing" or twisting in strong air flow. Constructed from thick 10?gauge 304 stainless steel with polished hardware included and sold as a pair, these anti?sail plates add weight to the bottom edge of universal mud flaps so they hang more consistently and reduce excessive movement behind truck or trailer tires. Because they're designed as universal, non?OEM parts, checking your existing mud?flap width and mounting setup before ordering helps ensure proper fit and a smoother installation experience. These plates are backed by a warranty against defects in workmanship and materials from the purchase date and are typically special?order, non?returnable items.
