The Hendrickson S-36186-8 16-inch SURELOK Ride Height Lock Assembly Kit helps maintain trailer suspension height during loading and unloading. Its locking mechanism holds the suspension in position to help limit height changes as cargo is added or removed, supporting a more stable trailer platform during these operations. Designed for compatible Hendrickson suspension systems, this replacement kit supports service and maintenance of the existing ride height lock mechanism. Out of the box, the assembly kit measures 44.5 inches long × 25.5 inches wide × 7 inches high and has a net weight of 32.40 lb. These unpackaged measurements provide a reference for handling, storage, and service preparation. Confirm compatibility with your trailer’s suspension configuration before installation.
