6. Setup & Installation
The CURT 16424 brackets are designed for a custom fit, often utilizing existing frame holes to minimize drilling. This section outlines the general installation process. Refer to the detailed instructions provided with your CURT 5th wheel rail kit for specific torque values and complete steps.
6.1. Pre-Installation Steps
- Park the vehicle on a level surface and engage the parking brake.
- Disconnect the negative battery terminal.
- If necessary, remove the spare tire to provide adequate working space.
- Clear any debris or obstructions from the truck frame where the brackets will be mounted.
6.2. Bracket Installation
These brackets mount underneath the truck bed and are designed to accept industry-standard 5th wheel rails above the truck bed. They are intended for use with CURT rail kits #16104 or #16204 (sold separately).
- Position the brackets on the truck frame according to the specific vehicle application. The custom design ensures they align with existing frame holes where possible.
- Use the provided fish wire tool to guide bolts through the frame and into the bracket mounting points.
- Secure the brackets to the truck frame using the supplied hardware (bolts, nuts, washers). Do not fully tighten at this stage.
- Once the brackets are loosely secured, position the 5th wheel rails (sold separately) onto the brackets. Ensure proper alignment.
- Drill any necessary holes through the truck bed and frame as indicated by the rail kit instructions. For custom-fit brackets, drilling into the frame is often minimized or eliminated.
- Insert the remaining hardware to secure the rails to the brackets and the truck bed.
- Important: Before final tightening, place your 5th wheel hitch or Anderson hitch into the rails to confirm proper fitment and alignment.
- Tighten all bolts to the manufacturer's specified torque values. Refer to your rail kit instructions for these specifications.

Note on Sensor Control Module (if applicable): Some vehicles may have a sensor control module near the installation area. Factory wiring may limit movement. If relocation is necessary, consider leaving the clip closest to the tailgate in place and securing the clip closest to the cab with a zip-tie, or use an installer-supplied bolt and nut to place the relocation bracket closer to the sensor.

7. Operation
The CURT 16424 5th Wheel Installation Brackets serve as a foundational component for your 5th wheel towing system. Once properly installed with compatible 5th wheel rails and a 5th wheel hitch, their operation is integrated with the hitch itself.
- Ensure the 5th wheel hitch is securely mounted to the rails, and the rails are firmly attached to the brackets.
- Always follow the operating instructions provided with your specific 5th wheel hitch for coupling, uncoupling, and towing procedures.
- Regularly inspect the connection points between the hitch, rails, and brackets for any signs of wear or loosening before each towing trip.
8. Maintenance
Proper maintenance ensures the longevity and safe performance of your CURT 5th wheel installation brackets.
- Regular Inspection: Periodically inspect the brackets, bolts, and all connection points for signs of corrosion, damage, or loosening. This is especially important after towing or exposure to harsh weather conditions.
- Cleaning: Clean the brackets with mild soap and water. Avoid harsh chemicals that could damage the A-coat finish.
- Corrosion Protection: The brackets feature a durable A-coat finish for corrosion resistance. If the finish is damaged, touch up with a rust-inhibiting paint to prevent rust.
- Fastener Torque: Re-check the torque of all mounting bolts periodically, especially after the first few towing trips, to ensure they remain tightened to specifications.
9. Troubleshooting
This section addresses common issues that may arise during or after installation.
| Problem | Possible Cause | Solution |
|---|---|---|
| Brackets do not align with frame holes. | Incorrect bracket orientation or vehicle application. | Verify the brackets are oriented correctly (left/right) and that the product is compatible with your specific vehicle year/model. |
| Difficulty inserting bolts into frame. | Obstruction in frame or improper use of fish wire. | Ensure the frame is clear. Re-attempt with the fish wire, ensuring it's properly attached to the bolt. Some minor adjustments or "coaxing" may be needed. |
| Rails do not sit flush on brackets. | Debris, incorrect rail placement, or untightened bracket bolts. | Clear any debris. Ensure rails are correctly positioned. Loosen bracket bolts, adjust rails, then re-tighten. |
| Loose connection after towing. | Bolts not torqued to specification or settling of components. | Re-check and re-torque all mounting bolts to the specified values. Perform regular inspections. |
