Product Overview

The gas spring, measuring 21 inches extended with a 48 kg force rating, is a universal support strut with ball-stud end fittings on both ends. Gas springs like this are used across a wide range of vehicle applications, including hatchback and trunk lids, hoods/bonnets, tailgates, and rear windows, making this a useful general-stock size for distributors and workshops working across mixed-vehicle repairs.

A worn or failing gas spring typically shows up as a hatch, hood, or tailgate that won't stay open on its own, drops slowly under its own weight, or requires manual support to hold position. GSK Auto manufactures this gas spring at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to help confirm compatibility before shipping.

What Is a Gas Spring?

Function: A gas spring (or gas strut) provides controlled support force to hold a hinged panel, such as a hatch, hood, or tailgate, in an open position, while also cushioning its closing motion.

Working Principle: A pressurized gas cylinder houses a piston connected to an extending rod. The compressed gas pushes the rod outward, generating a controlled, consistent force that supports the weight of the panel it's attached to.

Importance: A properly functioning gas spring is essential for safe, convenient operation of hatches, hoods, and tailgates, preventing sudden drops that could cause injury or damage.

Common Failures & Signs: Panel that won't stay open on its own. Panel that drops slowly or suddenly under its own weight. Reduced resistance felt when opening or closing. Visible oil residue or leaking around the cylinder, indicating a loss of internal gas pressure.
