Wanted to chime in here a few years later and update everyone about my solution to tired/ worn out lift gate struts on my 2016 J200.
I bought these:
https://www.amazon.com/dp/B09K5C7YNW?tag=ihco-20
Brand is: A-Premium and is Chinese
But only after much confusion about what to get because the non-electric/ automatic lift gate but post 16+ nature of the 2016 made
Amazon, chatgpt, and the internet in general confused and totally unable to recommend products.
These were plug and play and even with my Gobi ladder have PLENTY of lift power. My old struts could keep the door up, but not with a 1/2 inch of snow on it for reference on gone-ness.
Tip for removal of stock arms is to start with the top. Prop and remove the door/ lift gate, then unscrew the top two bolts. This gives your crescent wrench access to the previously too-small space btw the lower ball joint/ bolt combo that is one piece, and does not snap on like some other lift gate struts.
Thats all I got. Will post again here if they fail or are not good - otherwise consider these a plug and play option.
Forgot to mention: the new strut ball joints do not come greased. Grease them before mounting to vehicle and work it in.
