These are not hard to install.
Make sure you raise the back of the truck at the hitch or somewhere that is not on the axle or leaf springs.
CAUTION: Put wheel chocks under front tires or stabilize truck from rolling because the rear tires will be about an inch off the ground.I found it easier to bolt on the top part of shock first and then use a second floor jack on the shock itself.
Be careful,you can pinch your hand on these.

Bought these 8 months ago. They worked very well while on pulled trailers, little did I know the spring started to favor one side when it becomes compressed and begins to rub the plastic dust boot, it makes a horrible sound as if your shocks are going bad. The spring has worn almost the entire one side of the boot away. Good idea but bad design by Monroe. Contacted Monroe on the problem they told me to rotate the spring on the seat. (Didn't work). They then told me to take it back for a replacement, which is what i'm doing today.

    These shocks will help support the tongue weight of a trailer I plan to purchase. They are fairly priced and look great. Easy installation with a somewhat stiffer ride as one would expect.

      Comments about Monroe Load Adjusting Shock Absorber:

      Totally eliminated shuffle and stutter felt when crossing bridge joints on the interstate at crusing speed. Antilock brake triggers less now too. Used to feel every bump, not now. 14 year old oem shocks not leaking but were shabby. Night and day difference after putting these on. Should have done it at 75K miles instead of 145K. Rides better than when new. Get them.
      Have a way to compress the coilover springs before you start the install to eliminate headaches. Other than that soak down bolts with rust buster the day before and be ready to install with hand tools the next day.

        Comments about Monroe Load Adjusting Shock Absorber:

        I installed the shocks on an '04 1/2 ton Silverado. I don't haul regularly but on the occasions that I do carry a heavy load handling suffered and I had to be careful crossing railroad tracks, etc. to prevent bottoming out. With the Sensa-Trac shocks, body roll is greatly reduced around corners and the suspension hasn't bottomed out. The shocks also prevent the back end from drooping which improves steering/handling. Ride quality is improved since the Silverado 1/2 ton 2 wheel drive has a rather soft ride for a truck. There is no harshness to the ride whether loaded or not. It's too soon to know how durable they will be, but I am completely satisfied with their performance at this point.

              It only took less than one hour. These shocks are well made and gave my truck the " new truck ride "
              I once had. I use my truck to cary my tools and
              supplies to the job. I am well pleased.

                  I love these shocks. When I put my riding mower in the back it still sits level. When I tow my camper it handles much better. It got rid of the porpoising when driving on rough roads. You will need to lift the truck by the frame to install, you can't compress these by hand to get them in place.

                      Hello Bob, Good question, I would recommend the Reflex Monotube Shock for your truck as it has the best ride control especially if you will be towing a trailer. There are many options available because of the different suspension upgrades for your truck, Give us a call at 1-877-ADVANCE (238-2623) so we can help you select the correct shocks.
