GEN-Y Hitch GH-8060 Executive Torsion-Flex King Pin Fifth Wheel Box Instruction Manual

Introduction

The GEN-Y Hitch GH-8060 Executive Torsion-Flex King Pin Fifth Wheel Box is designed to enhance your towing experience by significantly reducing trailer inertia transfer. This system allows the tow vehicle and trailer to track independently, improving control and safety by minimizing sway and trailer bounce. It also contributes to increased braking control through even weight distribution. The torsion-flex technology provides a smoother ride, reducing fatigue on both the driver and the trailer's contents, thereby extending the life and value of your equipment.

This manual provides essential information for the proper installation, operation, and maintenance of your GH-8060 Executive Torsion-Flex King Pin Fifth Wheel Box.

Product Features

• Fabricated with Heavy Duty Steel for maximum durability.
• Designed for a 30,000 LB Towing capacity.
• Engineered using Solid-works, ensuring precision and reliability.
• Features a virtually maintenance-free design with no airbags to maintain or bearings to crush or wear out.
• Supports a 3.5K - 5.5K Pin Weight range.

Setup and Installation

Proper setup is crucial for the safe and effective operation of your GEN-Y Hitch Executive Torsion-Flex King Pin. Please follow these steps carefully.

Determining the Correct Executive Model

To ensure compatibility and optimal performance, it is essential to select the correct Executive model based on your specific towing requirements and trailer configuration. Do not rely solely on the hitch/pin weight listed on your trailer.

1. Determine your connection type:
   • Standard Fifth Wheel Connection
   • Gooseneck Connection: This eliminates the need for a bulky fifth wheel hitch in the truck bed. If choosing gooseneck, you can select between a Manual or Auto Latch Coupler.
2. Confirm your trailer's frame model:
   • The frame model number can often be found on your original pin box.
   • If the model number is not available, refer to the specification sheets on the GEN-Y Hitch website to match the bolt pattern.
   • Contact the frame or trailer manufacturer if unsure.
3. Determine the required Executive size:

   To calculate your loaded pin weight, take 22% of your trailer's Gross Vehicle Weight Rating (GVWR). For example, if GVWR is 16,800 lbs, the calculated pin weight is 16,800 x 0.22 = 3,696 lbs. This example would correspond to the 5.5K model.

   Use the following guide based on your calculated pin weight:

   • If calculated 1,600 - 2,599 LBS, use the 3.5K model.
   • If calculated 2,600 - 3,599 LBS, use the 4.5K model.
   • If calculated 3,600 - 4,599 LBS, use the 5.5K model.
   • If calculated 4,600 - 5,599 LBS, use the 6.5K model.
   • If calculated 5,600 - 6,599 LBS, use the 7.5K model.
   • If calculated 6,600 - 7,599 LBS, use the 8.5K model.

Fitment Chart and Additional Components

Refer to the Executive Fifth Wheel Fitment Chart to verify compatibility with your trailer's OEM or GEN-Y replacement pin box. Note that some applications may require additional components.

• For Lippert 1116 or 1716 frame models, a Shim Kit (GH-8000) is required.
• When ordering a Fifth Wheel to Gooseneck model, Safety Chains (GH-70684) must be purchased.
• New hardware for installation may require a Bolt Installation Kit (GH-80943).
• If using a sliding fifth wheel hitch, purchase the Capture Plate (GH-70924).

Product Dimensions

The GH-8060 is designed to fit Lippert 1621 & 1621 HD pin boxes directly. It can also be used with Lippert 1116 & 1716 models, but requires shim plates (GH-8000).

Operating Instructions

The GEN-Y Hitch Executive Torsion-Flex King Pin is designed for a smoother and safer towing experience. Follow these guidelines for optimal operation:

1. Connection: Ensure the king pin is securely connected to your fifth wheel hitch or gooseneck coupler according to the manufacturer's instructions for both the hitch and the trailer. Verify all safety mechanisms are engaged.
2. Weight Distribution: The torsion-flex system inherently distributes weight more evenly, reducing stress on both the tow vehicle and trailer. However, always ensure your trailer is loaded correctly to maintain proper tongue weight and balance.
3. Driving: Experience reduced sway and bounce due to the independent tracking of the tow vehicle and trailer. This allows for greater control, especially over uneven terrain, bumps, and expansion joints.
4. Braking: The improved weight distribution enhances braking control, providing more positive contact with the road during deceleration.
5. Monitoring: Periodically check the connection points and the overall condition of the hitch during long trips.

Maintenance

The GEN-Y Hitch Executive Torsion-Flex King Pin is designed to be virtually maintenance-free. However, regular inspections are recommended to ensure continued safe operation.

• Visual Inspection: Before each tow, visually inspect the hitch for any signs of wear, damage, cracks, or loose fasteners.
• Cleaning: Keep the hitch clean from dirt, road grime, and corrosive materials. A mild soap and water solution can be used, followed by thorough drying.
• Lubrication: While the torsion system itself requires no lubrication, ensure that any moving parts of your fifth wheel hitch or gooseneck coupler are lubricated according to their respective manuals.
• Fasteners: Periodically check all bolts and nuts for proper torque. Refer to the installation instructions for specific torque values.
• Storage: When not in use for extended periods, store the hitch in a dry environment to prevent corrosion.
