These highway pegs are designed with a rubber insert to provide better traction and more comfort when riding. They will mount on any 1" or 1-1/4" crash bars. The 44 mag shells are made from actual 44 mag bullets and come in your choice of nickel or brass. The 44 mag shells are slightly recessed into the rubber to offer better protection from normal wear and tear. The highway pegs also come with a matching 44 mag shell bolt cover for the pivot bolt on top and a nut cover for the bottom of the bolt which gives the appearance of a bullet going through the peg. (Matches or bullet license and windshield bolts and nuts) Available in Brass or Nickel
