Tired of wrestling with a heavy manual tailgate every time your hands are full? Decoin's power liftgate kit brings effortless, one-touch operation to the ChangAn Cos 1, letting you open and close the cargo area with your key fob, a dashboard button, or even a foot swipe. It's a simple upgrade that makes daily errands noticeably easier.
The ChangAn Cos 1 wasn't built with an electric tailgate from the factory, but Decoin's power liftgate kit closes that gap without any guesswork. Every part is sized and calibrated for the Cos 1's tailgate hinge and weight, so the fit feels original rather than bolted-on.
A whisper-quiet motor lifts and lowers the Cos 1's tailgate smoothly, without the clunks or jolts of a generic aftermarket unit. You'll notice the difference the first time you load groceries or luggage.
If anything — a bag, a curious pet, a stray hand — gets in the way while the tailgate is closing, the system senses the resistance, stops, and reverses automatically. Paired with double bar support that exceeds factory strength standards, the Cos 1's tailgate stays stable and evenly balanced at every height.
Open and close the tailgate using your existing Cos 1 key fob, a button near the driver's seat, or the tailgate-mounted switch — no extra remote to carry or charge.
Set a maximum opening height once with a long button press, and the Cos 1 will remember it every time — handy if your garage ceiling or a low carport doesn't allow full-height opening.
Installation uses simple hand tools and comes with a full instruction manual (paper and digital), so most Cos 1 owners have the kit fitted and working within a couple of hours.
Will this kit fit my ChangAn Cos 1 without modifying the body? Yes, the kit is designed to bolt onto the Cos 1's existing tailgate hinges and struts with no cutting or drilling.
Can I still open the tailgate manually if needed? Yes, manual operation remains available at any time, even with the power liftgate installed.
Does it work with my factory key fob? Yes, the Cos 1's original key fob operates the power liftgate directly, so there's no second remote to manage.
