🔧 Enhancing Performance: Progressive Suspension 412-4020B Black 13" Shocks Unleashed Review

I noticed a difference on the first two rides after installing these shocks. No bottom and noticeably smoother overall. Costs money. I will install progressive springs next week. 2003 street slide.

Great shocks for the money. I installed them on a 1999 Road King. The ride is much better than standard pneumatically adjustable setups. Installation took about 20 minutes including installing the tool kit (head and open end wrenches).

I was skeptical about how much cheaper they are than the next best thing but I was pleasantly surprised. Both in terms of ease of installation and ride quality. Adjustments are effortless and I barely felt the crappy roads we were on.

Installed on my 2001 Roadking Classic was great. Installation took about 30 minutes. You need an elevator. I bought Progressive 444 shocks for my Ultra Classic and loved it so I decided to try the more economical 412s for my Roadking. As a 240-pound rider, I opted for the heavy-duty shocks when riding with two people or when I have a touring pack.

Along with the mono tube kit these shocks made my 03 Road King handle better than new. A big improvement over stock. ***** UPDATED *****. After 3+ years I have to say that these shocks and the mono tube front suspension upgrade were possibly the best upgrade to my Road King that I have ever invested in. They still handle great and are a huge improvement over the stocks. Rest assured you won't be disappointed.
