A worn or damaged trailer king pin can compromise safety and lead to costly downtime. At PJ Spring, we provide complete trailer king pin and bushing services—including inspection, replacement, and repair—to keep your trailer coupling safe and secure. Our technicians accurately assess wear and cracks and, if needed, remove and install new king pins using proper heat and press techniques. We also replace worn bushings with durable OEM-grade parts to ensure correct articulation and alignment. For fleets or single trailers, we help maintain DOT compliance and reduce the risk of disconnects or excessive fifth-wheel wear.
