I bought these for my '06 FLHR and could not be happier. I'm 6' 275 lbs so I went with the heavy duty option. Took about 30 min. to change shocks and the ride has improved considerably, took the jolt out of hitting heaves in the road.
While removing the rear wheel for some other service they just quite literally fell apart in two pieces leaving me with a garage floor full of suspension oil and one unusable shock. Spoke with their warranty rep who told me in so many words that its not their problem. Dissapointed to say the least.
So far loving these, the ride is much smoother and an awesome look. Going for the 12" was a good choice, raised it but not too much.
Just changed from my stock Harley to the 13-in and what a difference it made. Bike handles better and rides better
