C1608054 20" Gas Prop Spring Strut 20 inch 100 Lb Per Shock C16-08054 for Camper Shell RV Bed Tonneau Cover Storage Box Basement Door Floor Hatch Window Lift Struts (Applicable Lid Weight 85-110LBs)

Perfect fit

They worked perfectly on my hard top tonneau cover.

I had ordered a pair of these to replace the ones I have for my truck's tonneau cover. One showed up not working but the company sent a replacement set pretty quick. Overall, they are a great product, very strong and the company is reliable, very quick to reply and very easy to deal with. I highly recommend these

Given the force these struts produce, I assumed they would come with the 13mm ball end fittings, but no. They are fitted with 10mm ball ends, so I had to order the 13mm ball (8mm thread) fittings separately. The one I have in use seems to work ok but time will tell how they hold up on a snowmobile trailer clamshell cover that gets a ton of salt spray in the winter.

The piston located on the bottom side of my travel trailer door had gone bad and the door would not stay open. Even the lightest breeze would cause the door to close. I removed the old piston and noted that there were various numbers printed on the side of it. I got on Amazon and started searching and found the piston with the same numbers as what I had, and in the same size as my old one. The new item arrived a day later, and it was super easy to install and now it firmly holds the door open. I got the 15 lbs holding power version and it is perfect for the door.
