Hatchlift RV Door Lift Kit – Light-Duty Hydraulic Strut for Secure, Easy Access to Storage, Cargo & Compartment Doors – Durable and Reliable Support – Fits RV Doors 21 to 27 Inch in Height – Standard

These go on very easily. Instructions are simple. About the only thing I will say is you need to predrill the plates for the piece the strut attaches to. Predrill them before installing them on the door. The door in this situation is just a foam core door and you don't want to drill all the way thru the door. So mark up the plate before installing and drill a small hole so the self taping screw will go in easily. Then install the plate to the door.

I recommend this product.You will need to be fairly manual to install this.All the pieces that you need are in the package.Works really well.No issues.

I installed only one shock on hatch size that was recommended ton install 2, just 3 inches larger than recommended. I’m satisfied by the results that I might keep only one per hatch. I ordered just 2 to test so I will be able to complete 2 hatches. Hatches are 33wX20h

Great product! Easy to install. My only issue is, I wish you could order cylinders with a little less strength in them for doors like mine. My doors are VERY cheap and lightweight. SO much so that the inner panel on 1 door is now moving around inside the frame. Not the Hatchlift's fault. It works great and I'm sure it will work better with heavier doors. The reason I use them is because when the doors are open and the wind blows the doors smash into the side of the camper.

You only receive one ram and for my instalation 2 were required and I had to order a second one Double you cost but it was worth it to get the installation hardware.
