Anybody running the air shocks on an Interstate? I just put some 412HD on my bike and was bottoming out on #4 setting. I talked to justin at progressive and he made me a deal on some 416s to help with the problem. I had returned the 412s to them to have them checked out. They could find nothing wrong with them or the HD springs.I just don't understand the 412 as I only weigh about 265lbs. I can't spring for the 440 right now but the 416s I can swing. Anyone running the air now.
