Description
Overview
The Fuwa K-Hitch 50mm greaseless fifth wheel top belongs to the Highway Master KA12A50 range. Its pressed steel construction features a single-piece adjustable jaw for coupling to a 50mm king pin. This B-double rated assembly includes the foot pivot pins and rubber bushes, allowing the top to be fitted with the appropriate mounting feet.
The greaseless wear pads reduce the need for lubrication across the fifth wheel’s upper contact surface. Meanwhile, the adjustable jaw allows technicians to set the correct king pin clearance during servicing.

- Greaseless wear pads and adjustable single-piece 50mm jaw.
- 174kN D-rating and 20-tonne vertical load capacity.

Compatibility and Fitment
Match the existing 50mm king pin, fifth wheel mounting arrangement and required coupling height before ordering. This assembly carries a B-double application specification, so confirm the intended installation meets the required rating.

Compliance and Safety
Confirm the 174kN D-rating and 20-tonne vertical capacity against the approved vehicle combination. After installation, inspect the pivot pins, bushes and mounting hardware, then complete the manufacturer’s locking and jaw-clearance checks.
Although the top uses greaseless wear pads, the locking mechanism and other service points still require appropriate inspection and maintenance.
Trailer Applications
The Highway Master range supports general freight and B-double highway coupling arrangements. This 50mm greaseless fifth wheel top provides the upper coupling assembly for a compatible heavy vehicle installation, with separate pivot feet determining the final mounting configuration.

- Identify compatible pivot-foot components, replacement bushes, pins and jaw service parts when planning a Highway Master repair.
- Send through photos, existing part markings and mounting dimensions so ICS Trailers can assist with identifying the appropriate coupling arrangement for your vehicle.
