Hey there! As a supplier of Tailgate Gas Springs, I often get asked about the dimensions of a typical tailgate gas spring. So, I thought I'd write this blog to share some insights on this topic.
First off, let's understand what a tailgate gas spring is. A Tailgate Gas Spring is a type of gas spring specifically designed to assist in the opening and closing of vehicle tailgates. It uses compressed gas to provide a controlled force, making it easier to lift and hold the tailgate in place.
Now, when it comes to the dimensions of a typical tailgate gas spring, there are several key aspects to consider.
Length
The length of a tailgate gas spring is an important dimension. It usually refers to the overall extended length of the gas spring when it's fully open. This length is crucial because it needs to match the requirements of the tailgate's opening mechanism. If the gas spring is too short, it may not be able to fully lift the tailgate, and if it's too long, it could cause interference or improper operation.
Typically, the extended length of a tailgate gas spring can range from around 300mm to 600mm, but this can vary depending on the make and model of the vehicle. For smaller cars or SUVs, a shorter gas spring might be sufficient, while larger trucks or vans may require a longer one.


Stroke
The stroke of a gas spring is the distance that the piston rod can move within the cylinder. In the context of a tailgate gas spring, it determines how much the tailgate can be opened or closed with the assistance of the gas spring. A longer stroke allows for a greater range of motion of the tailgate.
The stroke length of a typical tailgate gas spring can be anywhere from 100mm to 300mm. Again, this depends on the design of the vehicle's tailgate and the desired opening angle. For example, if a tailgate needs to open wide, a gas spring with a longer stroke will be needed.
Diameter
The diameter of the gas spring's cylinder is another important dimension. A larger diameter generally means that the gas spring can handle more force. Tailgate gas springs usually have cylinder diameters ranging from 16mm to 25mm.
The choice of diameter depends on the weight of the tailgate. Heavier tailgates require gas springs with larger diameters to provide enough support and lifting force. For instance, a heavy-duty truck tailgate will need a gas spring with a larger diameter compared to a light - weight car tailgate.
Mounting Dimensions
Mounting dimensions are also crucial for proper installation of the tailgate gas spring. This includes the size and type of the mounting brackets or eyes at both ends of the gas spring. The mounting points need to align correctly with the corresponding points on the vehicle's body and the tailgate.
The size of the mounting eyes can vary, but common sizes are around 8mm to 12mm in diameter. The shape and orientation of the mounting brackets also need to match the vehicle's design to ensure a secure and stable installation.
Force Rating
While not strictly a dimension, the force rating of a tailgate gas spring is closely related to its performance and the overall design. The force rating indicates the amount of force that the gas spring can exert. It's measured in Newtons (N).
The force rating of a typical tailgate gas spring can range from 200N to 1000N. The appropriate force rating depends on the weight of the tailgate and the desired ease of opening and closing. A heavier tailgate will require a gas spring with a higher force rating.
Now, it's important to note that these are just general guidelines. Different vehicle manufacturers may have specific requirements for their tailgate gas springs, and aftermarket gas springs need to be carefully selected to ensure compatibility.
