I have been using Monroe shocks since the early 80's. Ran them on Camaro's, Dusters, Malibu, etc.
I just replaced a 24yr old pair of Monro-Matics on the front of my 73 Duster. Amazingly one of the shocks still had a slight charge of nitrogen left in it. I installed a brand new pair of monro matic plus (standard gas charged replacements like I had) and the car drives fantastic.
If you are running stock spring rates and want a smooth/controlled ride on a budget these are durable enough. Not saying they will last 25 yrs but mine were still dampening ok, they passed the bounce test which ain't saying much. $30.00/PR you get what you pay for and they work great.
