We developed these sacrificial splitter scuff plates (or biscuits as we've been referring to them) to be easily replaceable and to protect your splitter from road and curb rash. They have a secondary benefit of keeping your splitter from completely sealing off against the ground and reduce fluttering or "porpousing". You can get the complete kit, or just the bottom biscuit. They could also be utilized as a slick way to attach some splitter rods should your splitter need them. They are sold individually so be sure to select as many as you need, plus a spare or two. Threads are 1/4-20.
