Hello to you all, hoping you had a great new year celebration, i come with this doubt: I´ve noticed the inminent signs of shock absorbers wear, and right now money is a little tight, and the other day while in autozone, i asked for the price of their product, and they had duralast (hidraulic), and duralast gold (neumatic) shocks, has anyone had any previous experience with these?? are they average, good or completely useless?? im at least expecting them to last for like 4-5 years. It is for a 2001 xls, four door, v6 explorer. Which one should i choose?? Any input will be highly appreciated, thanks!!!
