Dose the progressive shocks help handling at higher speeds 70-90 mph? Over stock air shocks?
Hi DB, shocks can improve handling at speed, but are not the solution if you have handling difficulties. If you haven't done so, read my thread on bagger wobble for a complete explanation for what I suspect you are experiencing.
Per Progressive Suspension web site regarding standard vs heavy duty rated springs: "Heavy Duty Applications are recommended for bikes that are operated at or near the manufacturer’s maximum load rating over 50% of the time."
That's the theory I went with. Me 185 LBS, wife 135 LBS. The HD springs were way to stiff and harsh for my liking. Had them switched to standard. Seems to ride much better. The shocks are 944's.
Air shocks SUCK! Period, now IMO Progressive Suspension is NOT the best route to go. Suspension Techology is far way better than the overrated "Progressives crap" that everyone seems to rave about but don't have any clue what a true suspension component is. ANYTHING is better than stock even if its junk! Bikers tend to have a perceived idea about Progressive because after all Harleys don't come w the best suspension system but some cheap low end quality chinese made crap... Yup, this is an "AMERICAN" bike! Sad that Harley has to skimp the consumer w lower quality parts... But we ALL love Harleys...
Talked to the guy at Suspension Technology and he said that their shocks are comparable to the 444's maybe a little better but that the progressives are not a bad shock, I have had progressive shocks on 2 of my other bikes and liked the ride so just decided to stay with something I had experience with. Thanks for your input maybe my next shocks I will try the Suspension Technologies shocks.
I agree the stock air shocks suck. I ran 100,000 miles on mine and just ordered the Arnotts air system. A Bilstein damper with a true air spring. Comes with compressor, switch, hoses, and wireing for just over 500 bucks. I'm adding a Legends air pressure gauge where the stock air temp gauge is, and like the idea of easily adjusting the pressure for load or conditions at the touch of a switch. Let you know how they work out.
Thanks for the write up that had a lot of good info, but I'm not sure if it that sever. So what do you think of the true track?
AFAIK they are the people who started the rear stabilizer thing, in other words were first to introduce one. Many of the other brands copy their design, to some degree. I have used TT kits on my Dyna and Glide and they are a very worthwhile improvement, tightening control and handling at all speeds.
