Default Shocks questions????

Here is a pic of my bike http://picasaweb.google.com/dan.malt...20294118957906
I have Progressive suspension black shocks. I wonder was that stock on a 82 Sporty. She rides a bit rough, like most sportsters. I was thinking about upgrading my shocks. What shocks will fit on the sportster I wanted to ask all the guys that actually know what they are doing, for Id have to get somethign that does not fit. What size of shock came stock with the bike 13 in??
What is the purpose of lowering the back, and what should I lower it to? 10.5, 11, 12???? I think its to make the bike look cooler with the back being all low, but how much can you go before you start to bottom out on your fender. Also what is the deal with the gas shocks, I see alot of guys putting them on hi-performance sportys. Do gas shocks do somethign special. Another option was to put on like a Road Kinig Air shock system, I saw some posts on the forums of guys doing that. I like the Progressive 440, but they are big bucks.
Basically my question is what do you think is the best shock for the sportster as bang for the buck goes.

mandaltby, Be aware that Ironheads, at least my 1975, does not use the same shock as the new Sportys. You must buy shocks for an Ironhead. A new Evo shock will not support the rear of an Iron, because of the different mounting points an Iron shock needs to be much stiffer.

Stock for '82 was 12.5" eye to eye. You can probably put 11.5" shocks on without much worry, but the shorter you go, the worse it will ride. Short shocks have stiff springs to keep them from bottoming due to the short travel. If you want a lower rear, I think 12" shocks on the early 80's bikes look best and still ride OK. What length do you have now?

If it ain't broke, don't fix it (especially if you don't know what you're doing). Most Sportster problems are owner-induced.

Thanks for all the responses. I will try and adjust them. I dotn know maby my shocks are fine. I know that the rubber washers by the 4 mounting points is cracked and rotten, I could start with that. But Im thinking that my shocks are 30 years old Id think that replacing them would give me a nicer ride. What does everyone think about putting Road King Air Shocks on the sporty. I saw some posts here of guys doing it. It seems that it would work since you just adjust the air pressure yourself. Or are my shocks still good if I replace the rubber grommets that go around mounting holes.

If you decide to go with other shocks, let me know. I might have a project those black shocks would be perfect for.
