Technical Details and Construction

The StrongArm 4857 gas strut features a steel outer cylinder finished in black for corrosion resistance and durability. It has a compressed length of 13.11 inches and extends to 18.66 inches, providing a stroke length of 5.55 inches. The inner shaft diameter measures 10 mm, ensuring strength and stability during operation. The ends are designed for specific fitment: a 10mm nylon ball socket on one end and a captive ball blade with bracket on the other, allowing secure attachment to the Jeep Grand Cherokee components. The inclusion of rubber and Teflon materials helps reduce friction and wear, contributing to longer service life. This gas strut does not include an internal rebound spring, focusing on smooth and controlled motion under load.
