This kit replaces the (2) wimpy stock rubber rollers that roll on a 6mm bolt top and bottom that disintegrate after very little riding time. Also replaces the heavy steel "U" shaped bar that holds them together. Kit contains (2) high quality 98A durometer hardness polyurethane rollers complete with precision contact sealed roller bearings, (2) (bearings per roller). These are the same rollers that came stock on the 85-97 Honda CR's. Also comes with a pre drilled 6067 aluminum backing plate, 8mm stainless steel bolts, washers and nyloc nuts. Actual Husqvarna brake stay arm is not included and is only for display purposes. Installs in minutes and is lighter and much more durable than the stock set up with no drag at all. Fits all Husqvarna models from 1967-1974 including 1975 WR models. Feel free to ask questions. It will be necessary to drill out the (2) 6mm holes in the stay arm to 8mm.
