I just got finished putting progressive 430 rear shocks on my street bob. They are 11" normal spring (not heavy duty). I looked under the rear fender and was wondering if I have to worry about tearing up the wiring. I ride 1up 99% of the time and weigh 175. I just dont want to mess anything up.

 

It's definitely something to be aware of, check under the fender after a short ride to see if there was any contact with the wires. If so, you have to reroute them, and if not keep an eye on it. For a while I was running 11.5" Progressives and the tire was rubbing a little. Corrected that situation but then went to longer shocks anyway.

 

You will be okay. Should be checking things anyway.
2 up, I betcha you bottom out.
Had HD 11inch shock and had em on the max. Solo it was good, 2 up it bottomed a lot.

 

I have 430s on mine, no problems so far.

 

The 412 12" shocks only have 1.9" of travel. Another member checked an 11" Prog shock to find only about an inch of travel. The wires on my Dyna go down each side, under stays. So, they are not top dead center. Your experience may differ.

Happy Trails

 

Thats what I was looking for, thanks alot. I took it out today for a very short ride as its only 20 degrees out. Im glad to say everything seems like it will clear all the wires. I will keep checking after it gets warmer out and I can go for a real ride.

 

I had 12" HDs on my SB, which bottomed out if I sneezed. Changed to Prog 12" 412s and never bottomed out again - stiffer springs overall, but the the progressive-wound design of the springs makes them stiffer the further they are compressed, making bottoming out difficult/unpossible, in theory at least.

That said, that inch difference between my 12" and 11" could be critical... Agree with the advice from others above. Find a lumpy road, ride, then check. Try it two-up and check again. Maybe wipe some chalk on your cable covers (it's messy and dark up there, so would help with early detection of minor rubbing.)
