Default Road King shocks custom cut to size

Upon researching Road King (RK) shocks here on the web and on EBay, I think I may have found the perfect solution to this neverending debate. Not only the debate in my head (I want them, I dont want them) but also the debate here as to making them lower for a sporty without using the lowering blocks. Debate again (they are safe, they are not safe).
The standard shock RK & FLH shocks are 12.75" the lowered ones (on a Street Glide)are 11.75" . This company will take apart the shock and can lower them upto 2.5" from stock length. The standard size has a softer spring rate than the smaller ones. This is why the Street Glides have a harsher ride quality, shorter stiffer spring. I talked with the owner who seems to think that the standard shock cut down to 10.5" will be soft enough for myself at 160# with room to add air to take a passenger by adding more air. That would realisticly leave about 1.5 to 1.75" of travel. Granted you could cut down to any length and increase travel or decrease travel, to your prefrence.
I would like to here some opinions from those who have the standard 12.75" and the lowered 11.75" shocks to compare the ride quality and harshness of hitting bumps. Remember I am 160 and over 300 with passenger.
If you have had this done chime in please.
The web site for the company is.
http://bitchinbaggers.com/products/drop-shocks/
I hope this helps others get dialed in with these shocks.
You can send yours in to be cut down for $175 or buy from them direct for about $275 if you dont have the shocks to send in.
Thier ebay site is.

good luck

I saw them too and hope someone chimes in with advice. I already have my shocks and need to make a decision before I install them.

The first question is what is he doing to cut down the shock? Is he reusing the same spring? What other internal modifications does he do? Why do you want to lower the bike and still expect it to carry 2 up? Which bike are you going to put them on?

I weigh 260 lbs and think the 13" RK shocks ride too stiff because the spring rate is too stiff. I bought them from a guy who weighs 150 lbs, way too stiff for him. Shortening the shock will only make it worse because you will also likely bottom out much more quickly. If he is reusing the same spring, the initial part of the shock's travel will not change, it will be just as stiff.

Adding too much air pressure to carry extra weight may reducing dampening because the shock tends to bounce on air pressure rather than moving the oil through the shims and ports which create dampening.

I think I remember him saying that there is an internal stop inside. A rubber stop I think that is repositioned. Yes the same springs are used. I wanted the shorter shocks for the lowered look. And air adjustability for adding a passenger. On my hugger. I am 160 and 5 pounds of pressure on my EG standard is like a cloud. I know they are seperate bikes and wieght and set up, but should it be that great a diff between the 2 bikes as far as the ride quality.
I was told that if cut down to 11" should still have about 2" of travel. I want to lower my EG standard as well but the Street Glide shocks have a heavier shock spring rate. As compared to the 13" shocks on the rest of the touring bikes.

I just rememberd that I now have an Electra Glide Standard and that will be used for two up, so I guess I wont be putting them on the sporty but will get them cut for the Standard. The seat hieght is just a tad to high, I can easily flat foot but my thigh is to close to the exhaust which empties right under my left leg.

Here's a link with pictures of RK air shocks which I cut apart to figure out if it was possible to make internal adjustments and then get them back together. In my pictures, you can see the rubber bumper, it is very small and won't protect your back much in a hard bottoming out situation.

If you INSIST on the lowered look, theses shocks might work on for you on the heavier bikes. However, two up on a lowered bike will always have serious limitations unless you are lucky enough to get the perfect spring. I suppose you are going to pay your money, and take your chances.

I suppose the guy has made some special jigs to get them apart. I suppose he cuts the smallest shaft which screws into the top shock body/mount.

I decided on the lowering blocks for mine (at least for now). I might try to get a set of lowered airs from the guy listed above at a later date.....

OH Mohntonite I would like to say that I had a Road Glide so I would'nt have to worry about this, but I didn't win the powerball last night. Maybe Wedensday!!!LOL
