FU Boards for the 2012 and up Pro Climb and Pro Cross chassis sleds. Made from  1/2" marine grade HDPE with a textured finish, these running board inserts put a end to snow build up on your boards. Designed to compliment the stock running boards, leaving as much of the stock board behind as possible. Fastens to your sled using included stainless hardware. Stainless nylock nuts double as traction, making for a truely slip free running board. (note.....an air body saw is recomended for installation.)
