Compatibility and Fitment

Match the king pin size, skid plate design, fifth wheel coupling type and bolt pattern before ordering. Also inspect the skid plate, mounting holes and fifth wheel jaws, because worn mating parts can damage a new pin or create unsafe coupling movement.

Compliance and Safety

Inspect the king pin for wear, looseness, cracking and damaged mounting hardware during service. Replace the bolt kit when the mounting hardware has stretched, corroded or lost clamp load, then torque the assembly using the trailer or coupling service procedure.

Trailer Applications

Workshops fit a 50mm king pin with bolt kit during semi-trailer coupling repairs, skid plate service and fifth wheel connection inspections. It suits fleets that need a complete pin and bolt kit rather than a pin-only replacement.
