The real deal
I don't have the receipt handy. They didn't have the "kit" in stock, so I had to buy the seals separately. 2 wipers, 2 seals, and 3 sixteen oz. jugs of the heavy fluid was around $55 at the dealership. Had I thought ahead, I would have ordered the parts online, and used Shock Therapy from Amzoil. Could have probably shaved $20 off the cost.
I think the fork rebuild is recommended around 40 or 50k miles. And I didn't think I needed to replace the (bronze?) bushings. So the kit would have left me with spare parts.
I was able to fab my own seal driver from seamless 2" schedule 40 pipe, and tapered the outside of the end to minimal wall thickness. It was only about 3" long, and heavy enough to just "slide hammer" the seal into place. I also covered the tubes with masking tape, to make sure I didn't scratch the surface of the tube. I've read that you can use PVC pipe to do the same. That would guarantee you don't scratch the tubes. And- of course- you can buy the Genuine HD tool. I have no idea what that costs.
I rebuild many forks and I actually know what I am doing as well as know what the parts are used for and how they are suppose to work. My purpose is to give our members some insight on what they should be looking at, how to inspect the forks for wear, and understand what wears. If anyone wishes to not listen than immediately skip my post as I do not sell these parts and I need to get to work. I am hoping I am not wasting my time.
In less than or at 10K miles your FLT fork oil is filthy, contains contaminants, & is black from being heated up. I would never use any HD oil but that is just me observation, there is a difference in fork oil. If you dump your fork oil into a cup in less than 10K using HD oil, this is what you will see. No trick photography here. This bike only had 6K miles on it and belonged to member AdrainVail @ HDF.
And leaves settled debris (dirt, metal deposits, Et. al.) that looks like this
In about a week or two the suspended debris in the dumped oil settles and there is a good coating in the bottom of the cup. I swab out the inside of the fork tubes and you will find this:
I outline how to clean your forks in a two part video hosted on my site. Amy is not a paid actor and actually knows what she is doing and does her own work.

The slider and guide bushings are just carriers so a coating can be applied such as Teflon so the fork tube can either slide through the bushing (top/guide) and the slide bushing slides inside of the fork slider that is captivated onto the fork tube.
These are not brass or steel bushings but carriers. Next, inspect your fork tubes while you have them apart. Hard Chrome can not buff to get shinny. If you see shinny, chrome like spots, congratulations, you just saved $3.50, $4.50, and the cost of your oil by not cleaning your forks at 10K miles. Yes, 10K not 50K miles on a FLT. If your fork tubes have long scratches in the hard chrome, you are well on your way of wearing out your fork tubes. I hear all of the time that 10K is way too much maintenance and money to do. Of course your only option is to now purchase new fork tubes and all of the wear parts.
When you have all of that suspended debris floating around it is like suspended abrasive power thus wearing out your parts and once the Teflon coating is worn off your forks start slowing down and do not operate as intended thus your ride suffers in both ride quality and performance.
Amy volunteered her time to make that video over several days & I am passing along information that I know is true a I do this stuff every day (most days anyhow). You can do what you like as it is your bike, however, this information, you can take to the bank.
