I am adding a second disc to my 2006 883. I found a reasonably priced stainless dual disc kit on Ebay for a 2005 FXDX.

The banjo fittings appear to be the correct angle. Does anyone know if they are compatible?

I don't know if they are compatible, but I think banjo fittings can be replaced. My after market lines didn't come with them, had to buy them separately.

Someone with more knowledge will be along shortly.

Did the kit include a new master cylinder ? Single and dual have different bore size master cylinders and different size outlet fittings.

Harley has used two banjo sizes, 10mm & 12mm. Make sure you get the right size. Like Schmidty mentioned, different size master cylinders used for single & dual disc systems (9/16" & 11/16"). Your master cylinder doesn't move the volume of fluid needed to move extra caliper pistons PROPERLY. I've read debates if it really matters or not. I would want a matching system.

we are only talking about brake lines here. I am aware of the master cylinder issue.

I have opted for a Dennis Kirk build your own brake line kit. It has the correct banjo fittings (2-10mm, 1-12mm).
