      Comments about Monroe Max-Air Air Shock Absorber:

      These shocks were great, well almost. It took a bit of fiddle to get them to work for my Olds Ciera. The wheel wells are so tight that I had to install airlines facing out. Then zip tie the lines to the shocks themselves. I routed the lines thru a hole I drilled thru the wheel well into the trunk as under the car all the sharp metal edges would have shredded the small lines. I slid the lines thru rubber hose and drilled 1/4 inch holes and painted the hole greased the hose with vasaline and hooked it up. I wish monroe would sell a cheap pump unit to put in the car to adjust from the front instead of having to open trunk and set height.

      • Q:

        When I order a quantity of one how many do I get? The picture in the add shows two. Does that mean a quantity of 1 is one pair?
