What makes the Severe Service shock different?
It's an extra-durable, gas-charged design with strengthened components, a larger bore for greater working capacity, and arc-welded mounts for higher tensile strength, built for the toughest fleet and construction uses.
What does the nitrogen gas charge do?
The nitrogen gas charge reduces aeration of the fluid, helping maintain tire-to-road contact for improved ride and handling.
