Description for Progressive Suspension Drop-In Front Fork Lowering System

• This fork Lowering Kit has transformed a once messy, and time consuming install into an easy install

• Pull up to two inches out of the front end of your bike without the hassle of disassembling the forks, pulling the wheel or even changing out the oil and the whole process can be done with basic tools

• Shorter springs and Progressive's secondary compensator spring make short work of the formerly complicated act of lowering your front end

Note: Requires fork tubes to be removed from top triple tree.

Awesome simple install

West Texas Infidel

If I was only allowed to change one thing on my bike this would be it, even if I planned on retaining the stock height. Not sure I can explain how a couple springs can make such a difference but my front suspension is somehow smoother, firmer and lighter all at the same time. It's like a different bike altogether. I've been handing my bike over to friends (something I hardly ever do) for them to check out because I know they will want to change theirs also.


Great product, good price but my favorite thing about J&P Cycle is always the fast shipping!!


Bought this for my HD Dyna Wide Glide FXDWG the instructions do not apply to this model and there is a bit more work involved to install. Have yet to complete installation; will to update once installed.


Great kit. Easy to install once bat wing was removed .


great product, I read some reviews that guys r mad because on a full bagger it wasn't a "drop in" kit...u have to be pretty dumb to not realize u have to take off the fairing and or drop the fork legs out to access the top of ur fork tubes to install these springs. I have them on both my 89 sportster and 09 street glide.




Great product and as always a great deal from JP Cycles. Thank you. Cant wait to see you guys in Sturgis this year.


Gave me the stance I was looking for on my bike great ride height.


Was not a drop in application as advertised. Forks had to be removed. It was not a simple drop in as the video advertised.


The product itself is great however when installing this in a Road Glide it is anything but "drop-in." This was very misleading and caused severe frustration. The forks WILL have to come off for a touring bike. All videos show a Dyna which are clearly very simple to change.


Dropped Road Glide an inch. Big difference for short guy backing it out of garage now. Stiffened up front end nicely, I did not like the bouncy feeling anyway. Handles great.


Good product. No instructions. Definately not drop in on a Street Glide.


Purchased this for my '08 Night Train, and even though I had to slide the fork tubes out of the top clamp, it was still only a 30 minute job. I did the 2" drop, and it looks perfect now! Another great product from J&P!


Fast shipping was nice.


This was the simplistic install ever . I used it with the progressive drop in front


Great quality part from progressive suspension. Clear instructions (factory service manual required though) made the install easy, and the ride is great!


Always fast delivery and the product arrived in superb condition. Thanks again for top notch service.


Excellent Product, very easy to install


Very easy to install. worked great! Made the bike much lighter.


To Cool and one of the easiest mods I have done To my bike . I had already Put 10 inch Rear Shocks last season. putting Those drop ins dropped The Bike To a perfect low Profile. it Rides Perfect and hugs The Road. and with My 18'S Its almost There , a Few More Parts and she will be dressed. J and P will be my go To Place. I know People That own and Run Bike Shops and Can not beat your Prices .


Simple to follow instructions. 10 min. job with usual progressive quality at a great price


Good to go!


Was told it would fit my bike...Harley fxstd but it will not. Tried to get help from your techs but all they do is just look at info in the comp same as I could do. called progressive and got the same from them. recieved no help from jpcycle or progressive. Since the product was not as described I returned it for a refund. love jpcycle have ordered in the past with no problems.


This kit was EASY MONEY, I had to adjust the directions a little bit from the OEM Video, but she still went on Easy.


Very happy easy to install instructions were very clear. Bike looks super bad 2 inch lower!!


Not difficult to install. Doesn't compromise ride quality.


Awesome lowering kit. Easy to install!


Performed as expected, got 2" of drop. Ride is a little rougher than stock, but have not given it time to break in yet. It may soften up in time.
