    Comments about Monroe Load Adjusting Shock Absorber:

    I bought this for my 1987 K5 Blazer. Advance Auto Parts web site said this product will fit my blazer. For those who have a 1987 K5 Blazer let me save you some time, "This does not fit." After some modification to the product I was able to get it to fit. So the question is will I recommend this product to a friend? I would recommend this product to a friend if it fits there vehicle. After installing them the ride is a lot smoother even when going over bumps/railroad tracks. I gave this product 4 out of 5 stars because it didn't fit my vehicle until I modified it. If it would of fit my vehicle right out the box I would of gave it 5 stars. Great product.

      THE SHOCKS GAVE MY TRUCK A MUCH BETTER RIDE THAN THE AIR SHOCKS THAT THEY REPLACED.........THEY PERFORM GREAT WHEN CORNERING AND DO NOT LET MY TRUCK SWAY. THE RIDE IS EXCELLENT.......THEY GIVE A GREAT CUSHIONED RIDE EVEN CROSSING ROUGH RAILROAD TRACKS......I WOULD RECOMMEND THE SENSA-TRACK SHOCK TO ANYONE REPLACING SHOCKS.........THIS IS MY 3RD SET OF THESE SHOCKS...........

          Restored original ride height. Not too rough of a ride. Only downside was that they didn't come with the lower nut/bolt combo for the lower end of the shock.
