Trailer Kingpins

Weld On

Use these kingpins as the primary connection and pivot point between your semi-trailer and semi-tractor. They help the trailer turn and move with the tractor to remain stable and balanced during towing. Made of 8630 alloy steel, these kingpins are strong and hard. Plus, the addition of chromium in the steel protects them from corrosion in wet conditions. Install them on the underside of your trailer.
