Montube cartridge kit

By   on  Verified Purchaser

Pretty straight forward installation as long as you know what your doing. I put these on my iron 883 (2016) and they look great!


100% Improvement.

By   on  Verified Purchaser

Easy instillation, improved the ride and handling 100%.


Progressive mono tube front shocks

By   on  Verified Purchaser

I finally got my 1990 flhtc dresser on the road after neck race and bearing and fork rebuild. I installed progressive fork cartridge mono tube stock height with three pe load spacers each side for stiffer handling and pulling my bushtec trailer. Bought my bike new and has 144000 miles on it now. I've been use to the anti dive stock set up, but must admit I love this progressive inners! I'm still running stock rear air shocks.


Great ride

By   on  Verified Purchaser

Easy installation.


Will be upgrading the rear

By   on  Verified Purchaser

These progressives are amazing for an upgrade from factory. Will be upgrading the rear soon.


Feel the difference

By   on 

Feel the difference on straight roads, however, real different in the twisties! Feels more secure. Holds the lean without the "pogo" feel!


Just installed

By   on  Verified Purchaser

Just installed, all good. Rides better, longer ride, can tell more because of adjustment factor. This smoke in my area is holding me back from riding. Check back.


Bike is now rideable!

By   on  Verified Purchaser

Made a world of different on the ride quality on my 1200 Nightster; it does not rattle your teeth loose now. Fairly easy to install but messy getting the oil out of the stock forks. A must for any Harley with the original dinosaur front suspension; also added rear Progressive 13.5" shocks and no longer drag the pegs on slow turns.


Great handling

By   on  Verified Purchaser

Great handling and performance! Went from a slammer kit to these and it was night and day! Love the ride quality.

Different bike now, just right

By   on 

Much better ride quality. These put my Softail Custom in a different league. I used two spacers because we ride double most of the time. Wasn't sure if it would ride too hard, but I got lucky and it was just perfect.

Questions & Answers


Does this kit replace my air ride front fork stock setup?

2000 road king.

Yes, that's correct. These cartridge kits completely replace all of the internal fork components on the 2000 FLHR Road King. The air ride components will be removed to facilitate this kit's installation.

By Tom

Hi I have a 1997 flht Electra looking to purchase. How much fluid is used or recommended for each fork and does it come with all seals caps clips every thing

In the case of the 1997 FLHT's fork cartridge kit, you'll need 5 oz. of 10W fork oil for each fork. As for seals, none of those are included in the kit. You can re-use the OEM components if they're in good condition. That said, considering the age of the bike, and since you're already halfway there, you might as well put some new seals and/or bushings on while you're at it. That way, there will be no question as to the competency of your new fork internals. And yes, you WILL notice a difference in front end feel upon installation of this cartridge kit. It's really worth every bit of effort!

By Tom

2012 street glide. Is this stock ridding height?

Yes, Progressive's cartridge kit for the 2012 FLHX Street Glide will retain the original ride height of your bike's forks. The included instructions will explain exactly how to go about fitting these internals to your machine so you can maintain that stock ride height.

By Tom

i Have a 93 flhtc would I be putting a cartridge in both legs

Yes. The 1993 Harley Davidson FLHTC Electra Glide Classic fork cartridge kit from Progressive includes cartridges for both fork legs.

By Tom

Does progressive have the needed oil to add to my order

Yes, Progressive does offer fork oil. If you search our website for Progressive Fork Oil, it should pop right up for you.

By Andy

Can this lower front 2 inches

This kit would not provide a lowered stance. If you would want to have the front end lowered, you would want to go with the Progressive Lowered Monotube Cartridge Kit. Simply search for Progressive Lowered Monotube Cartridge Kit on our website and you will find it.

By Andy

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

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.
