Black DLC 39mm Fork Tubes – Harley Dyna, FXR & Sportster

Want to clean up the front end of your Harley?

If you're going for a blacked-out front end, or you're planning to run longer fork tubes on your Dyna, FXR, or Sportster, these Elite Black DLC 39mm Fork Tubes are worth a look.

They're finished with a black DLC coating over hard chrome, giving you that clean black appearance without relying on paint or powder coating.

We offer them in both standard length and +2" overstock length, so whether you're replacing your original tubes or changing up the stance of your bike, you've got a couple of options.

And yes, they're sold in pairs.

What's the Deal with DLC Coating?

DLC stands for Diamond-Like Carbon.

It's a hard, low-friction surface coating used on a variety of mechanical components where wear resistance and smooth surface movement are important.

These tubes use a black DLC coating applied over hard chrome, combining a durable surface finish with the black appearance a lot of riders are looking for.

It's a nice alternative to traditional chrome fork tubes, especially if you're building a blacked-out Dyna, FXR, or Sportster.

Standard Length or +2"? Here's the Difference.

We offer these tubes in two lengths:

Standard Length – 24.25"

If you're happy with your bike's current front-end setup and just want to replace the existing tubes with black DLC, this is the option to look at.

Just make sure the 24.25" measurement matches the correct replacement length for your particular application.

+2" Over Stock – 26.25"

Looking to get a little more height out of the front end?

The +2" option gives you tubes that are two inches longer than the standard version listed here.

They're a popular choice for riders changing the stance of a Dyna or FXR, but keep in mind that longer tubes alone don't guarantee two additional inches of suspension travel or exactly two inches of ride-height increase.

Your springs, internal components, suspension setup, and overall front-end geometry all play a part.

If you're going longer, make sure the rest of your setup is compatible.

A Quick Note About Fitment

Not every Harley with a 39mm front end uses the same fork tube length or internal components.

Before ordering, verify your fork diameter, original tube length, and the internal components you're planning to use.

This is especially important if your bike has a swapped front end, aftermarket suspension components, or a custom setup.

Planning to Go +2" Over Stock?

Longer fork tubes can change more than just the appearance of your bike.

Depending on how your front end is set up, changing tube length can affect ride height, rake and trail, handling, and available suspension travel.

You'll also want to check:

• Brake line and cable length

• Fork spring and internal component compatibility

• Front fender and tire clearance

• Full suspension compression and extension

• Proper fork assembly and alignment

If you're building a taller front end, it's worth planning the whole setup rather than just swapping tubes and hoping everything works together.

While You're in There...

If you're already pulling the front end apart to replace fork tubes, it's a good time to take a look at the rest of your suspension.

Depending on the condition of your existing components, you might want to consider replacing worn seals, inspecting bushings, or upgrading your fork springs or cartridges.

It's a lot easier to handle those things while the forks are already apart.
