Rough Country Rear Vertex Adjustable Shock Absorbers for 2011-2020 Chevy Silverado GMC Sierra HD | 3.5-7.5 Lift | 699011

Ride is good. Day after installing, towed our 6000 pound travel trailer with weight distribution hitch and shocks on setting 5. Stable ride. Unloaded (have a fiberglass cap), the truck was stiff on default setting of 4. Tried 2 and then 1. At 1, they are just a touch more firm than the factory shocks (which were pretty weak) - providing a comfortable ride. I thought about waiting to review until after driving with a load in the truck bed. But knew if I did not do it now when prompted, I would get busy. As a sales rep, I often carry 200 to 500 pounds of sample gear. Hopefully can update this review after some trips on the road. Negatives include the instructions. The picture of the top is completely useless. There should be a simple exploded diagram of what part goes where. It is mostly intuitively obvious as you put it in place but I wanted to go into the project with confidence and not a feeling of winging it. The rope tied around the shocks to keep compressed was a poor idea. They were in the way and would be hard to undo when trying to install and unload at the same time. With the help of my daughter, I wrapped the shock with a ratchet strap to hold it compressed during install and removed the ropes. This allowed me to slide the bottom onto the pin by the axle and then rotate the shock up into the top hole. I had the wheel off and the frame on jack stands and a hydraulic jack under the axle. Slowly raising the axle with the jack allowed for the top of the shock to go into place and put on the nut. Then was able to release the ratchet strap and finish tightening up both ends. Put the wheel back on and done. Hope this helps others.
