- Forged locking jaw creates a solid and secure grip around the trailer kingpin
- Wide-throat design provides a larger target area for easier trailer hookups in tight yards
- Oversized pivot pins ensure the plate stays horizontal during aggressive turning maneuvers

JOST Yard Fifth Wheel Top Plate
The JOST Yard Fifth Wheel Top Plate is a heavy-duty ductile iron casting built with a wide-throat entry for terminal spotter applications. This specific model is outfitted with replaceable steel wear pads on the top surface to take the brunt of the friction during trailer swaps, protecting the main plate from thinning over time. The JOST JSK37YSA assembly includes an integrated air-release cylinder that pulls the locking handle via a pneumatic switch, allowing for faster uncoupling without the driver leaving the cab. To maintain a smooth surface between the plate and the trailer, the face is machined with standard grease grooves that hold lubricant across the entire contact area. These structural features are supported by thick pivot pockets and oversized pins that keep the plate stable and level even when backing under heavy or uneven trailers.
