Technical Details and Construction

The StrongArm 4620 gas strut features a steel outer cylinder finished in black for corrosion resistance and durability. The 22 mm diameter cylinder houses a piston with a 10 mm inner shaft diameter, ensuring a robust and stable stroke of 6.37 inches. Both ends are equipped with 10 mm nylon ball socket fittings, allowing for secure attachment points that reduce wear and noise. The internal components include rubber seals and Teflon materials to minimize friction and extend service life. This gas spring does not include an internal rebound spring, focusing on consistent damping force rated at 117 Newtons.

Compatible Vehicles and Applications

This gas strut is designed specifically for use with the Geo Impulse and Isuzu Storm models. It is ideal for applications requiring controlled lifting and support, such as hatchbacks, tailgates, or engine covers on these vehicles.

  • Supports smooth opening and closing of rear hatch or tailgate
  • Replaces worn or weak gas springs to restore proper lift assistance
  • Reduces rattling and noise from loose or failing struts
  • Helps maintain proper alignment and balance of supported panels

Installation Notes and Tips

When installing the StrongArm 4620 gas strut, ensure the ball socket ends are securely clipped onto the mounting studs. It is recommended to replace gas struts in pairs to maintain balanced support. Avoid compressing the strut manually beyond its specified stroke length to prevent damage. Lubricate mounting points if necessary to reduce noise and wear.

Quality Assurance and Warranty

StrongArm gas struts are manufactured to meet strict quality standards using durable materials such as steel, rubber, and Teflon. The 4620 model is tested for consistent force output and fitment accuracy for Geo Impulse and Isuzu Storm vehicles. Warranty coverage details should be confirmed with the product documentation or manufacturer.
