I have Rancho 5000's on my truck since i got it(on the second pair now) They are ok but i will go with Bilstein next time i replace shocks. Depends on what you drive and the road conditions. Here the roads are worse than "off road". They replace roads that are really not that bad and do nothing to the ones that desperately need it. They paint new lines on roads with tons of patches and cracks. Also replace the curb's and walkways instead of the road surface. Typical waste of the tax payers dollar.
