About one year old. Maybe 10K miles. These are awesome if you have a lot of weight in the rear, like bumper/fridge etc. These do not sag like the 2" springs by Icon. Great ride and look, especially when you have weight back there.
Camburgs have about 30K mi. on them. Great condition but would recommend picking up new bushings. Cheap kit, I might be able to get them prior to selling. PM if interested in them and I will get pictures later today.
