Post #9 should answer your question, but read the entire thread for further clarification...

Thank you all for your help!
I just ordered a set of 912's from www.davesport.com
They didnt give me the option of choosing Medium Duty or Heavy Duty so whatever they send will be fine. Is the same place Rickshaw ordered his from so i think it will be fine

Thanks again!

Also got the Daystar Spring Spacers - KC09103BK from Amazon.com
Unfortunatly I am out of the country untill the end of august so i wont get to install anything i bought till then. But i cant wait!

I got the 919s, they fit perfect, of course, I talked to the folks over at indy4x, the 919s are a tiny bit taller, but they have a much higher weight capacity, so if you plan on hauling stuff or towing, that would be the difference. Not sure if they ride different or not...

Nice post, that is the same info I used in my decision, if it requires more lbf/in to compress the 919 spring, that means it will sit higher under normal load or loaded than the 912 or 913, which equals more lift Add a spacer, and voila, you are that much higher. But that requires that much more torsion bar crank as well. Its just a matter of what you want, and the ultimate reason, the 912s and 913s were a 6-8 week, 919s were in stock shipped the next day
