The Superflex kit was installed when we bought jeep and it was brand new at time with very few miles on it.. dude spent over 3k on lift.. bumper.. tires & wheels and clutch master & slave then blew #6 piston to hell.. so.. I figured I would tell people that.. even tho this is a DD on road and never taken off road as of yet. I love the ride... its very nice.. even after 60k hwy miles..

 

Highway miles don't tend to "break in" cars like stop and go traffic and offroading do. So that will be where the suspension components will tell their tale. At the most, you've maybe acquired suspension settling and minor wear and tear from uneven road surfaces.

I'm happy to hear you like the ride. I personally used a Rough Country lift, but I used some nice Bilstein 5100 shocks and control arm drop brackets and loved that ride quality on everything I rode over.

It seemed like a Cadillac compared to the OEM Rubicon suspension I'm using now.
