TC Bros. Fork Tube Kit For Harley-Davidson 39mm (Late FXR, Early Dyna, and Evo Sportster)

If you’re rebuilding a fork and found the tubes damaged, you may need replacements. And if you’re building a chopper, you may require a longer fork. In either scenario, these TC Bros. kits will help you refresh a factory-length fork or convert your OE front end into a custom-length fork suitable for choppers with additional frame rake.

• This fork tube kit contains the items you need to extend hydraulic 39mm (commonly called “narrowglide”) front ends originally found on many Harley-Davidson FXR,  Sportster (XL) and Dyna (FXD) motorcycles
• Tubes are centerless-ground
• ID and OD match OEM specifications
• Fork oil available separately
• For superior performance, we recommend the use of a heavy duty fork spring
• Kit contains 2 fork tubes, 2 fork oil seals, 2 dust seals, 2 oil seal retaining rings, 2 oil seal O-rings, 2 damper tube bolts with washers, 2 oil seal spacers, 4 damper tube rings
• Full overhaul kits are available separately if your fork requires new bushings
  • Selecting both upper and lower bushings is nearly the same as adding a full overhaul kit except backup rings are not included—these are reusable on almost every fork, so it's usually much more economical to add bushings (and why we offer them!)
• Fork spring spacers are included where required (extended tubes)
• Detailed installation instructions are included
• Available in three finishes
  • Chrome
    • Hard chrome finish promotes responsive suspension action, low stiction, and helps prevent premature seal wear
    • Tubes are buffed and hard chrome plated for a durable finish 
    • Approximately 55-60 Rockwell hardness
  • Titanium nitride (TiN)
    • TiN coating reduces friction and increases wear resistance
    • An extremely hard ceramic material, TiN coating is approximately 85 Rockwell hardness 
    • Gives your fork the same visual appearance found on most high-end motorcycle suspension systems
  • Diamond-like carbon (DLC)
    • Diamond-like carbon (DLC) reduces abrasive wear and has an exceptionally low coefficient of friction
    • Approximately 75-83 Rockwell hardness
    • This finish delivers a stunning black appearance that’s a good alternative to traditional hard chrome
• Available in several lengths
  • Stock Length: 25” overall length
  • +2” Over:  27" overall length
  • +4” Over:  29" overall length
