Progressive fork cartrifge kit
I have an 08 FXD that I raked 3 deg and added 2" longer tubes to the forks. Does anybody know if the Progressive monotube kit for the 08 FXDWG will work with this setup? The new tubes are actually .413" shorter than the WG factory tubes.
I have tried emailing Progressive but as usual, no response after a week. I am unable to use a phone at work during their business hours, so limited to emails.
Thanks guys...

OK. new question, then. Who should I contact regarding setting the bike up with Works cartridges?
Apparently Progressive has all the customers their business model can support at the moment.

well, crap. Don't think I wanna spend the money on Ohlins. I know they are awesome, but I don't need that level.
Thanks for replying, though. Now I know they aren't an option.

Yeah, unfortunately I don't know crap about 06-up FXD forks. You could always go racetech.

I would not be surprised if the Progressive WG damping rods work.

I believe those Progressive Cartridges (like other brands) are made to fit OE sized applications, not deviations caused by using aftermarket tubes. Although someone installing them using a particular combo of parts may not be aware anything is "Wrong"
Using your situation as an example...
Progressive makes one kit for 2006-08 WG which has 27-7/8"Tubes and another for 2010-17 WG with 26-7/8".
Yours are +2 over FXD's 25-1/2" Tubes ... so 27-1/2"
If you used the 2006-08 kit for 27-7/8" Tubes, you would be pushing down on the cartridge from it's normal position to meet up with your shorter 27-1/2" Tubes ... thus using some the Cartridge's Stroke (travel) just for initial positioning.
If there wasn't enough "Extra" Cartridge Stroke, you would "Run Out" of Cartridge travel on extreme compression before you reached your physical Tube/Slider "Bottoming" ... No Bueno
But again, in that particular example, a person may not know that that is even happening or that it will happen

No, that "Lowering" method maintains the same Fork Tube-to-Cartridge relationship ... ie. the tube and cartridge are being moved the same amount
But when the cartridge is installed in the wrong length of tube they are moved independently from each other creating the problem I stated above.
Depending on your "Machining" Resources, there could be a few ways to overcome this through modification (if you're committed to these cartridges)...
Without going into all the details at this point about the different methods... (I have a call into Progressive, which hopefully will provide details for the "best" method)
The "best" method would maintain your existing approx 5" of Suspension Travel and the other method would sacrifice some of your suspension travel (while also effectively "lowering", but different than the Std way), which appears to be acceptable to you because your "Lowering" statement which also sacrifices suspension travel.
Since it seems you want to keep this Cheap as you can (Normal
), have you thought about Emulators and Springs ... Tube length would then be a "Non Factor" (except for preload spacer)
