The tail gate struts are rods which form part of the framework of the tail gate on the vehicle and are used to hold the tailgate/rear boot up and in place when it 's open.

The tail gate struts are positioned on either side of the boot so that the boot lid is held in place evenly and, with the action of hinges, opens outwards.

The tail gate struts use a gas spring mechanism to work, which uses gas inside a cylinder, compressed by a piston, to apply force, which keeps the strut rigid and extended and able to support the weight of the boot while it's open. This mechanism also helps to make opening the boot a smooth and easy operation. The internal mechanisms are housed in a rod which is sealed in an outer casing.

Loss of gas is the usual cause of failure in the tail gate struts. Damage can occur to the seal, enabling gas to leak out every time the boot is open, i.e. every time the tail gate struts open and shut. Faulty or broken tail gate struts may mean that the boot is hard to open, won't stay open fully or just slams shut again. When replacing the tail gate struts on your vehicle, buying new tail gate struts will ensure perfect compatibility with the make and model of your car. It's advisable to replace both sides of the tail gate struts at the same time to make sure the pressure is balanced and equal in both struts.
