    Comments about Monroe Max-Air Air Shock Absorber:

    These are easy to install. The hardest part of putting the new shocks on was getting the old ones off. Be extreemly carful not to break the bolts that go through the eyelets as the top ones are attached to the vehicle and this product does not come with the bottom bolt. the air lines are really simple to run. just drill some holes for the line clips and the air valve. Make sure that you put the line through the cap and then through the O ring and push it in the shock as far as possible before screwing on the cap this will prevent air leaks.

    Comments about Monroe Max-Air Air Shock Absorber:

    I installed these of a 1990 Ford Ranger 4.0. These are amazing and by far the best thing I have ever bought for my truck. I hauled 2,000 lbs of scrap in the bed with the shocks only at 120 psi. Differance is night and day if your shocks are old. My old shocks I could push and pull their full extent with ease. Installtion took less than 30mins. When I pull my trailer which is a 5x8 and my mower which weighs in at 760 lbs my truck does not even sag. Highlt recommend these.
