anyone know which length size that willmake it fit at thestocklengthfor my 06 street bob? DNA offers -2, stock(whats the measure?), 2, 4, 6 and go on. i'm not sure the correct length of the DNA stock length is. Anyone know before i can order it.

 

Call DNA. Give them your setup, wheels, rake, etc. and they'll tell you exactly what you need. Great guys. Here's the contact website:

I haven't had any trouble with mine, but, to each his own I guess.

 

Stock length is generaly 27" from bottom of top triple to rocker center. So you are probably a +2 or +4 but I would call DNA or what ever company springer you decide on to be sure.
I haven't used or seen a DNA springer but have heard they are a fine quality. I just worry about not using a shock and having a pogo suspension. Looking on DNA's site it doesn't appear they offer a shock either.
