Questions & Answers

  • Do I need new fork seals when installing this cartridge kit?

    By: Guest

    Provided your fork seals are in good shape, there's no need to replace them when installing the cartridge kit.

    By: Staff

  • Do i need to remove the tire and take the forks off to install this?

    By: Guest

    Yes, at the very least, you will have to remove the front wheel from your machine in order to install this Progressive fork cartridge kit. The reason being is that you'll have to loosen the bolt on the bottom of each fork that secures each OEM Harley fork cartridge in place. Plus, with all of the fork oil that will come out once each bolt is pulled, you're looking at a small mess, too. Unless you have something that can reach all the way to the bottom of the forks to suck out that oil, it's best to pull the forks off of the bike and drain them by dumping out all of that fork oil into a pan.

  • even with a cartridge do i need to replace the fork oil

    By: Rosey

    To do the work correctly, you will need to replace the fork oil in your machine and make sure it's at the appropriate level. Progressive is rather specific in the fork oil weight for a given application and, if the bike has ever had its forks serviced, it's impossible to say what viscosity is currently in there. If you need help in finding the correct fork oil to go with this kit, just let us know exactly what machine it is that you're riding and we'll be happy to find the correct weight and amount to fit your needs.
