easy install and the ride quality is way better than what it was, the previous owner had the torsion cranked all the way up with the control arms basically resting on the stops. I can now keep the ride height and comfortably go over speed bumps. and I mean you can't beat a warranty like kryptonite's. bonus, they look good too!

Exceeds expectations mostly
Over all very happy with the quality and made my truck ride a lot better. My only complaint is I got the powder coated and it would be much nicer if the kryptonite logo was engraved or riveted on in stead of a sticker
