Not that the stock shocks were that bad but the 422's are smooth as silk over bumps & potholes & after a nice 100 mile ride today I can say not one shock, no pun inteneded, ran up the spine. But the real test is when my SO rides with me. I set them to stock height although they do feel a tad higher & 2 full turns stiffer preload. For under 4 bills they are worth every penny. That's all folks! Install was a little tricky on a jack but went OK in about 3 hours.
