My 2005 Durango has about 107k miles on it and the shocks probably are about toast... I think they are original equipment.
Most of my driving is at moderate speed (under 50 mph) and most roads here are either rough asphalt with potholes or dirt roads.
I occasionally tow trailers, sometimes rather heavy at about 8,000 pounds loaded, so I prefer something rather stiff.
Any recommendations on what to replace them with?
