What is the name of the trunk torsion bar?

[VanBrooke]

The main function of the torsion bar is to assist in popping up the trunk. Not all vehicle models are equipped with these two torsion bars; some base models may omit them to reduce costs. Next, remove the rubber strip near the hydraulic strut to reveal the opening tension spring; new vehicles typically adjust the tension spring to the first position.

The crossbar in the trunk is commonly referred to as a trunk pneumatic support rod, also known as a hydraulic support rod or gas strut. It helps the trunk lid open and close smoothly, preventing it from suddenly slamming down. The rod in my car broke two years ago—not only was it hard to open the lid, but it almost hit my head, which was quite dangerous. After replacing it with a new pair at the repair shop, it felt much easier to use. The technician reminded me that these rods have internal gas pressure and may leak or rust over time, leading to failure. During regular maintenance, it's good to check the sealing and simply wipe off dust to extend its lifespan. Don’t underestimate it—if it breaks, address it promptly to avoid accidents, especially when there are elderly or children in the family car. Safety should always come first.

That rear trunk crossbar is called a pneumatic support rod, or more professionally, a gas strut. It's the key component supporting the trunk lid, filled internally with nitrogen or hydraulic fluid for cushioning. I often see it fail when repairing customers' cars: after aging, the rod loses elasticity, causing the lid to wobble or fail to open. The inspection method is simple - press the lid to check for resistance loss. When replacing, just choose one matching the original factory dimensions. It's inexpensive, costing just tens of yuan to fix, but delaying repairs can easily damage the trunk hinges. I recommend car owners perform regular maintenance and keep moving points lubricated.

The cross bar in the trunk is generally called a support rod or gas strut. This thing plays an auxiliary role when opening the trunk. As a beginner driver, I quickly understood that it helps with the lifting and lowering of the trunk lid. After some use, it may weaken, like mine which was replaced last year, costing only a few dozen bucks, and the mechanic fixed it in just a few minutes. Normally, when opening the lid, be careful not to pull too hard to extend its lifespan. It's a simple small component but very practical, directly related to daily convenience.

The crossbar in the trunk is technically called a gas strut, also known as a hydraulic strut. I think this component is very important. Once, when I opened the trunk lid, it suddenly slipped and fell, but luckily I dodged quickly. After replacing the new strut, it operates much more smoothly, and the sense of security has improved significantly. It is recommended to check it quarterly or during maintenance to see if there are any signs of oil leakage. If it feels loose, replace it as soon as possible. It's not expensive but ensures convenient operation—don't overlook the details while driving.

The standard name for the trunk crossbar is the pneumatic support rod. Some older models used spring-type supports in the past, but most have now been upgraded to the more reliable pneumatic design. With decades of car usage, I've seen numerous cases of these rods failing: decreased support force due to aging can lead to unstable trunk lids or unusual noises. If any issues are detected, timely replacement with new parts is a cost-effective and hassle-free solution. Applying lubricant to prevent rust and ensuring proper alignment during installation to avoid misalignment are recommended. Minor maintenance can extend its lifespan, ensuring smooth and safe operation.
