The INFINITI Hatch Lift Support (Right) is a long, pressurized cylinder that looks like a metal rod. Your INFINITI has one Hatch Lift Support on each side of the hood and hatch. Both Hatch Lift Supports are needed to hold open your hood or hatch. They are also sometimes called liftgate shocks or struts. When even one of your lift supports stops working, it can be dangerous to work on your vehicle or open up the hatch for everyday to-do's like packing for a road trip or loading groceries, since the hood or hatch might close unexpectedly.

Similar to your tires or car battery, a Hatch Lift Support (Right) wears out over time. Driving climate, temperature swings, and everyday usage can also impact a lift support's performance.

How do you know it's time for a replacement? You'll feel the full weight of the metal hood or hatch when you open it, since the lift support won't be carrying some of the weight. Hatch lift supports can be replaced at any time. There isn't a specific time frame you need to follow. It all depends on the wear and tear. There's a good chance a Hatch Lift Support (Right) lasts at least 50,000 miles.

Replacing the INFINITI Hatch Lift Support (Right) typically doesn't require special tools or automotive knowledge. If you're going to replace both Hatch Lift Supports, it's recommended you work on them one at a time. Don't remove both at the same time. With any questions, you can call on your nearby INFINITI retailer for installation help.
