stop to the front suspension when fully extended. Therefore, when
servicing the shock absorber, service replacement shock absorbers
must be equivalent to original shock absorbers in both extended

equipment or strength could result in suspension over-travel or
shock breakage. Suspension over-travel may result in suspension
component breakage.
