This super lubricant has been formulated specifically for use on trailer couplers, 5th wheel hook-ups, goose neck trailers, and load leveling hitches. It is designed for extreme pressures and shock loads over 100,000 lbs, such as trailer hook-ups, where low rpm is encountered. It is fortified with rust inhibitors, friction modifiers, and a special tack additive that keeps it from pounding or washing out under extreme conditions.
