Default Progressive fork springs

Will the installation of Progressive fork spring in my 05 Road Glide eliminate the need for the cartridge in the left fork leg?

I don't know the answer, however most people that I have known have not been happy swapping out their stock springs on a Harley.

The only reason I ask is so I do away with that damn cartridge. The thing looks like a pain in the *** to service per the maintenance manual. So I was thinking that while I was removing and replacing the fork lowers with chrome sliders I would get rid of it. I know all of the baggers after 05 have just the springs and no cartridge. Maybe I could just put in a set from an 06 or 07 bagger, the forks are the same except for the cartridge of course.

I'm gonna do the same thing. I have an 05 E-glide with the left cartridge also. Must not have been that good of a set up cause the moco went back to the old faithful style in 06. Pretty sure any Twin-cam Touring legs will go right on an 05. I'm also gonna make sure I re-fill with SE-Fork oil. The xtra weight of the oil is supposed to improve the front end feel a little.....Joe Mac

What parts are needed to get rid of the cartridge?

I'm going to be installing chrome fork lowers soon, and I too am getting rid of the cartridge.

I don't know anything about a cartridge, but I have put Progressive fork springs in many bikes...........it's worth it. Better front end performance, less bottoming out, won't sag from age or trailering. Best bang for the buck for the front. My '98 RG loves them.

The road king does not have the cartridge, you can see the difference in the HD manual, hope this helps.
