Thumbs up. The Best of Motorcycles and Power Sports

Used these on my 2012 HD Switchback. I threw it off just right, I didn't even have to lower the front end. A slightly stiffer ride, but worth being able to touch the ground safely.

Pros
  • One year trial period
Cons
  • There are even more interesting options.

but the bike rides great. it is HD 10 inch on my .

I have a WAY 260 and my shock absorbers are set to minimum, they are hard but the bike steers perfectly. this is HD 10" on my 1995 plan

Pros
  • Lots of positive emotions
Cons
  • Easy maintainability

2008 Dyna fxd on chassis

These shocks lowered the rear of the bike about 1 1/2 inches which was exactly what I was looking for. I installed them in about 30-45 minutes. I adjusted the damper spring tension. or sag when me and my girlfriend are both on the bike and the ride is ok considering you gave up some travel to lower the bike. being on a bike I've ridden them about 100 miles and so far I'm happy with them and they work well.

Pros
  • Easy install
Cons
  • weak

2012 Street Bob with Chassis

I came standard with sturdy crackers, my big 250 lb butt beat them. Destroyed 1 inch wiring harness under the fender. Got the high performance 11" and set it to preset 5. Didn't bottom out, ran 2 hundred or so miles yesterday with no rubbing or bottoming. we will see in time. If I edit this, will they break or suck. Some say the ride is tough, I say it's not. A bit like a Cadillac compared to a Slammer, but not stock either. They handle curves well. TO UPDATE! I put 10k on them, after breaking…

Pros
  • Good product for the price
Cons
  • Safety
