It includes bushings and related hardware (typically two KP149 bushings, two KP172 components, and one KP153BK base kit) to rebuild the coupling mechanism. The kit addresses the air-release models commonly found on heavy-duty tractors. You would replace these components when you experience excessive slack, clunking, or difficulty coupling/uncoupling the fifth wheel, restoring safe and reliable trailer connection.
