JOST Fifth Wheel Trailer Hitch Mount Bolt
Fifth wheel mounting hardware plays a vital role in trailer coupling safety. The JOST Fifth Wheel Trailer Hitch Mount Bolt is specifically machined to fit high-torque structural applications required in semi-truck hitch systems. This bolt contributes to the secure anchoring of the fifth wheel assembly to the frame, maintaining load stability during cornering, acceleration, and braking. When this bolt becomes corroded or weakened, the structural integrity of the hitch is compromised—posing risk to both equipment and load. Using OEM-specified hardware like the JOST SK73121-55 prevents improper fit and reduces compliance issues during inspections.
