High-Quality King Pin for Semi-Trailer 50mm (2″) and 90mm (3.5″)
The King Pin is a critical component for connecting a semi-trailer to a tractor (such as a truck). It is a cylindrical metal pin typically mounted in the saddle located beneath the front end of the trailer. When connected, the King Pin fits into the fifth wheel device on the tractor, enabling the trailer to safely attach to the tractor while allowing for a degree of rotation and swinging relative to the tractor. Striving for excellence and safety, Kales’ King Pin stands out among trailer connection solutions due to its unique design and unparalleled quality. Our King Pin not only meets the strictest safety standards but also excels in rust resistance and wear resistance, providing solid assurance for every transport.

Frequently Asked Questions
Can you customize the trailer design according to my requirements?
Yes, absolutely. As a manufacturer, we have a professional engineering team. We can customize the dimensions, loading capacity (e.g., 60 tons, 80 tons), axle brand (FUWA/BPW), suspension type, and paint color to suit your specific road conditions and transport needs.
What material do you use for the main beam?
We use high-strength Q355 or T700 steel for the main beam. This ensures the trailer is lightweight yet strong enough to withstand heavy loads and rough road conditions in Africa and Central Asia.
What is your production time?
Standard models usually take 15-20 working days after receiving the deposit. For urgent orders, we can even shorten it to 10 days. We will keep you updated with photos and videos during production.
What are your payment terms?
Our standard term is T/T (30% deposit, 70% balance before shipping). For large orders, L/C (Letter of Credit) is also negotiable.
Do you provide a warranty?
Yes, we provide a 24-month warranty for the main beam. For spare parts (like brake pads, lights), we supply original parts at factory cost for the lifetime of the trailer.
