Hey Kia Sorento owners! If your rear tailgate is getting weak and won't stay up anymore, this A-Premium power lift support is exactly what you need. This thing is a perfect replacement for the 2016-2020 Sorento models with power opener systems - and let me tell you, the fit is spot on. It replaces part numbers 81770-C5100, 81770C5100, and 615103, so you know you're getting the right piece. Installation is pretty straightforward if you're handy, but definitely make sure your vehicle has the power opener before ordering. The build quality feels solid - no cheap materials here. What's really nice is the packaging they use - thick cardboard and air column bags that actually protect the strut during shipping, so it arrives in perfect condition. A-Premium backs this with a one-year unlimited mileage guarantee, which gives you some real peace of mind. I replaced both sides on my 2018 Sorento and the difference is night and day - the tailgate pops right up and stays there securely. No more worrying about it crashing down on your head while loading groceries! If you're tired of propping your tailgate up with a broom handle or having it slam shut unexpectedly, this power lift support will make your life so much easier. It's one of those repairs that feels really satisfying to do yourself and saves you a ton compared to dealership prices.
