Overview

When you hitch a trailer, you want a connection that feels dependable. The Buyers Products KP20050 forged trailer king pin is designed for a solid 2-inch coupling and compatible with weldable bolster plate configurations. Forged from durable steel and heat-treated for a hard, consistent surface, this king pin aims to support reliable fifth-wheel operation through varied loads and conditions.

Key specifications

  • 2 inch SAE king pin for common fifth-wheel setups
  • Hardness maintained through heat treatment at 302-363 BHN, helping resist wear
  • Ultimate tensile strength around 150,000 PSI for robust performance
  • Available with weldable bolster plate thickness options to fit different mounts
  • 8-hole bolt-on version offered for flexible installation
  • Manufactured from AISI 8630 steel for longevity and reliability

These specifications translate into practical benefits on the ground: a durable mating surface, strong resistance to deformation, and compatibility with common mounting styles. The bolster plate options allow alignment with your existing frame design, supporting a cleaner, more secure installation.

Engineering and reliability

Designed with a user-focused approach, Buyers Products emphasizes engineering precision and sturdy materials. The KP20050 line reflects a tradition of building components that perform in real-world trailer applications, backed by a team of knowledgeable engineers and industry experience since 1946.

Real-world use cases

  • Frequent hitching in fleet operations or long-haul trips where consistent connection matters
  • Applications that involve heavy loads, vibration, and exposure to temperature changes
  • Replacing or upgrading an existing king pin while maintaining compatibility with standard fifth-wheel hardware

Note that exact performance depends on your specific trailer setup and installation. The KP20050 offers options that may align with your requirements, without asserting guaranteed outcomes. Always follow proper installation practices and verify fitment with your vehicle configuration.
