Bought for street bob knowing it would raise the back slightly. Great change to how it rides

As advertised, bolted up in about 10 min. Only get the heavy duty if your a big person or a lot of doubling. I’m 270 and love them

Put these on my 09 fxdb... Big improvement!!! Highly recommend. Bike rides great in the twisties and is a noticeably more comfortable ride on the crappy California roads and freeways.

Judging shocks can be a can of worms. They fit my Triumph after I had to remove the steel bushing inside of the shock. My guess it that they weren't truly made for my bike in spite of what the ad said. That said they work better than the manufacturer's shock.

The bike handles better than ever. These shocks are a huge improvement over stock. I highly recommend. The only thing I would do differently is go with a shorter shock to get the rear end lower.

I put these shocks on my 2009 Super Glide Custom. My wife and I do most of our riding 2up and with a loaded sis bar bag. We are possibly also going to add hard saddle bags. Due to the weight we opted for the heavy duty 12.6 " shocks. We decided to go with the original shock height as the person before us had a significantly shorter shock put on. Due to the increased weight added the rear fender was rubbing on the wiring harness for the tail lights when riding over bumps. The 12.6 " shocks give a lot smoother ride without the worry of rubbing. I suggest these shocks to anyone that is looking for replacements. In the future I will also be swapping the original fork springs with Progressive heavy duty fork springs.
