The Gen-Y Hitch GH-8040 Executive Torsion-Flex Fifth Wheel King Pin Box delivers superior ride quality and reduced trailer oscillation through its innovative torsion-flex suspension system. Engineered for heavy-duty towing applications, this king pin box absorbs road shock and vibration before it transfers to your truck bed, providing a smoother, more controlled towing experience.

Key Features:

• Torsion-flex suspension system reduces chucking and trailer bounce
• 21,000 lb towing capacity for heavy fifth wheel trailers
• Pin weight range of 1,500 to 3,500 lbs accommodates various trailer configurations

This king pin box is designed to replace your standard rigid king pin box, transforming your fifth wheel towing setup into a smooth, shock-absorbing system. The torsion-flex design is particularly beneficial for short bed trucks where trailer clearance and articulation are critical. By reducing the jarring motion transmitted from trailer to truck, you'll experience less fatigue on long hauls and improved handling on rough roads.

Note: Verify fitment compatibility with your specific trailer model before installation. Refer to manufacturer specifications for detailed installation requirements and dimensions.
