New 4340 Chromoly Drive Flanges for the hard core 4 wheelers. These are twice as strong as stock flanges or hubs. They come with six 5/16 dowel pin holes. We supply you with all 6 - 5/16 dowel pins which are much bigger than your stock ones and a drill bit to re-drill for the larger pins. Simply pull the 2 smaller pins out and re-drill for the larger pins. We also provide the dust cover cap.
