Progressive mono tube front shocks
By Charles P. on

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.

These progressives are amazing for an upgrade from factory. Will be upgrading the rear soon.
Feel the difference
By None 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

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!

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

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 terry 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.
How many stars would you give this product? Write a review.
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.
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.
Do i need to remove the tire and take the forks off to install this?
By Anon.
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.
