If you want the best made axle nut covers for your Harley Davidson then FTD Customs axle covers are what you want. After years of fighting the cheap caps we decided to design and make our own. CNC machined from billet 6061 T6 Aluminum and then powder coated. We use a stainless steel 1/4-28 set screw so they don't strip out and you will not have rust leaking from them. You want the best, now you have found them!!!
