TC Bros. Fork Tube Kit for Harley-Davidson 49mm Forks

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 49mm front ends originally found on late Harley-Davidson 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 damper tube rings, 2 oil fork cap O-rings, 2 damper tube bolts with washers, and 2 oil seal retainers
- 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
- Gold—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
- Black—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: 25.5” overall length
- +2” Over: 27.5" overall length
- +4” Over: 29.5" overall length
