RC4WD Lowboy Gooseneck HD Kingpin Fifth Wheel Height Adjust Tamiya RC Truck 1/14

RC4WD Lowboy Trailer Kingpin

The RC4WD lowboy trailer rides a bit too low in the front, especially with a heavy load. This part replaces the aluminum fifth kingpin plate and the front aluminum block with a block that raises the ride height of the trailer 12mm without modifying the towing rig. 

SCREWS & NUTS ARE INCLUDED (10x M3x20b + 10x M3 Lock Nuts)

There are recesses in the part that accept the nylocks and allow a tidy install. 


New ride height at the front of the bottom of the lowboy is now ~23mm. 

  • Direct bolt-on install
  • Provides additional ground clearance, especially needed when under load
  • 3D Printed Product
