🔄 SAF-Holland FW35 5th Wheel Coupling
The SAF-Holland (formerly Holland Hitch) 5th wheel coupling is the universal standard for connecting tractor units to semi-trailers across North America. Its 2-inch kingpin latch, automatic locking mechanism, and jaw assembly are specified as OEM on Kenworth, Peterbilt, Freightliner, and Mack. The SAF-Holland FW35 handles 37,000 kg gross trailer weight and incorporates a polyethylene wear pad that eliminates greasing intervals at 100,000 km — a major fleet operating cost reduction. All North American Class 8 trucks use the same 2-inch kingpin standard, ensuring cross-fleet trailer interchangeability.
