2011 Roadking Installation

Took me about 2hrs. start to finish You can do it by yourself, if good with tools. Remove the fog light bar, headlight ,nacelle, and take out bolt from brake crossover. Then you can access the fork nuts. Loosen the pinch bolts, then jack the bike up high enough to access fork caps, I used a piece of foam, to catch the cap when I loosened it, and popped off to keep it from banging the triple tree. If your not using a spacer easy to put cap back. I put a 1'' spacer, so a second set of hands would have been nice. I used a piece of pvc pipe, slid through triple tree to put pressure and re-insert cap. Then re-assemble. No special tools needed. Works great happy with the ride.

Poor at best

Two friends and I bought 2013 Road Glides. All three bought these based on sizes recommended by Progressive's website. All were professionally installed by three different installers. The fitment and shock absorption was so poor that my front fender was damaged. We all went back to the original springs. Even worse, Progressive will not respond to email or return phone calls. Would love to share pic but cannot upload. Avoid this like the plague.

Drop in Kit

Just finished installing this kit on my Harley FLHTCUI . If your good with tools , plan on about 3 to 4 hours, Aux lights ,fairing, Ignition Switch, front tire,fender and brakes all have to com off to get to the Right side of the front forks. then 2 bolts more and that comes off, dont tilt the slider over or the oil pours out the top . now the easy part , remove the top nut , remove the spring, install the kit re fill that oil I mentioned, Oh reassemble your bike. looks like about 1 1/4 to 1 1/2 drop, no trouble with fender and fairings rubbing, long ride tomorrow to test the ride

good purchase

The fork tubes do have to be removed from the motorcycle. It is not a 30 minute job as advertised. I takes about two hours to remove the tubes(on a FLHTK) and then 10 minutes to install the new springs in the tubes after you have them on the bench. Then another two hours to reinstall the tubes. It lowered my front end two and a quarter inches. It made the bike fit me real nice(I am 5'8"). The ride is a little stiff and the larger bumps do rattle your teeth a little. I expected that due to the decrease in fork travel. I feel much more comfortable at a stop light and when making slow turns with a rider on back.

Better ride

Disassembly was required on my 03 fxsti. This product took about two hours to install and the tire, fender and turn signals etc. had to be removed. However this was purchased at a great price and delivered very quickly from Dennis Kirk. My bike is now lowered and the ride is much better and slightly firmer. Wish I had done this several years ago.

Not for the typical home mechanic.

What they don't tell you is that you have to get to the top of the shocks. Special tools are required for that part. Installation may take only 30 minutes then, but you're looking at a days work just getting to that point and then putting the motorcycle back together. They're still sitting on the bench in my garage until I can get the bike in to have them installed.
