(888) 312-8812 Login SignupTop and bottom dimensions tell the service story for the Hendrickson Air Suspension Spring, with a 9.00-inch top and 11.06-inch bottom in a top-single layout. Those measurements help confirm that the spring matches the mounting points before the vehicle is back under load. The spring uses air pressure inside the rubber body to cushion movement as weight and road conditions change. Top-single construction also gives the mounting side a clear configuration detail for service checks. The Hendrickson S-20217 keeps air spring selection tied to the right end dimensions and mounting layout.
