I have used lowering blocks on my bikes for years(started using them 20+ years ago) and have never had any issues at all. Currently they are being used on my 2004 Ultra Classic and have been on there for over 5 years. Probably have 20k miles on them. Not only that, we(my wife and I) have rode it down to Tennessee 2 or 3 times and rode the Tail of the Dragon 2 up on it. I have never notice any stability issues with any of the lowering kits I have used and I ride my bikes hard. I have been road racing motorcycles for years and know what its like to have a bike get loose under you or a bike that is having suspension issues. As long as you are using a good brand manufacturer, you should be fine using them. Also.....I have never had any rubbing issues.

Primary piston is shortened and bump rubber is trimmed, then fluid is changed from 5wt to 7 wt. It means disassembly, remachining etc. Adding a spacer under the snap ring really isn't the right way to shorten a shock. It's the primary piston that needs to be modified.

 

Send your OEM shocks to http://bitchinbaggers.com/products/drop-shocks/

they will lower/rebuild your shocks to exactly what you want for a lot less than a new set of shocks. Just saying...

 

I have a set of 11" shocks shortened by Bitchin Baggers I will sell.

 

Air ride! Under $200 and you can raise or lower as much as you want

 

Thanks, Big Money, but I think I'll buy the Progressives.

 

You should look at Pro Action Suspension, they make 11" for Baggers and the ride is outstanding.
