Detailed Description of the StrongArm 6439 Lift Support

This trunk lid lift support from StrongArm is constructed with a robust steel outer cylinder finished in black to resist corrosion and wear. The 18.0 mm diameter cylinder and 8.0 mm inner shaft provide the necessary strength to handle the trunk lid's weight.
