JOST BOLT IN STYLE KING PINS
JOST bolt in kingpins are suitable for OEM and aftermarket replacement. Once the retention plate is installed the kingpin can be easily replaced in minutes by just removing the mounting bolts.
When properly installed bolt in kingpins will meet or exceed the performance requirements of the Federal Motor Carrier Safety Regulations (FMCSR), The Society of Automotive Engineers (SAE) and the Truck and Trailer Manufacturers Association (TTMA).

DESIGN FEATURES:

• Bolt in kingpins allow for easy and fast replacement of the kingpin, and at much less cost than weld in kingpins.
• The kingpin flange and bolts are recessed in the retention plate reducing the possibility of center loading of the fifth wheel.
• JOST kingpins are manufactured and inspected using the most stringent safety requirements.
