2. Setup and Installation

Installation of the CURT 13472 trailer hitch is designed to be straightforward, offering a custom, factory fit. However, certain vehicle models, particularly those with hands-free liftgates, may require a factory sensor relocation kit. It is recommended to consult the detailed installation instructions provided with the product or available on the manufacturer's website for specific vehicle requirements.

General Installation Steps:

1. Prepare Vehicle: Ensure the vehicle is on a level surface and properly supported. Lower the spare tire if it obstructs access to the installation area.
2. Clear Obstructions: Identify and temporarily move any components that may interfere with hitch placement, such as exhaust hangers or hands-free liftgate sensors.
3. Position Hitch: Carefully lift the hitch into position, aligning the mounting holes with the vehicle's frame. Assistance from another person is highly recommended due to the weight of the hitch.
4. Secure Bolts: Hand-thread all bolts first to prevent cross-threading. Once all bolts are in place, tighten them to the specified torque settings using a torque wrench.
5. Reinstall Components: Reinstall any components that were removed or relocated during the installation process.
6. Final Check: Verify that all bolts are securely tightened and the hitch is properly seated.

Important Note:

Models with hands-free liftgates will require a factory sensor relocation kit. Refer to the specific instructions for your vehicle model.

3. Operating Instructions

Once installed, the CURT 13472 Class 3 Trailer Hitch allows for the attachment of various towing accessories, such as ball mounts, bike racks (non-vertical hanging), and cargo carriers. Always ensure that the towing component's weight rating does not exceed the lowest-rated component in your towing setup.

Towing Capacity:

• Gross Trailer Weight (GTW): 6,000 lbs.
• Tongue Weight (TW): 900 lbs.
• Weight Distribution Capacity (WDC): 8,000 lbs. (with compatible weight distribution hitch)
• Weight Distribution Tongue Weight (WDTW): 900 lbs. (with compatible weight distribution hitch)

Safety Precautions:

• Never exceed the lowest-rated towing component (vehicle, hitch, ball mount, or trailer).
• Ensure all connections are secure before towing.
• Distribute trailer load evenly to maintain proper tongue weight.
• Regularly inspect the hitch and all towing components for wear or damage.

4. Maintenance

Proper maintenance will extend the life and ensure the safe operation of your CURT trailer hitch. The dual-coat finish provides excellent protection, but regular inspection is still important.

• Regular Inspection: Periodically inspect the hitch for any signs of rust, chipping, cracks, or deformation. Pay close attention to weld points and mounting areas.
• Cleanliness: Keep the receiver tube free of dirt, debris, and moisture. This prevents corrosion and ensures proper fit of accessories.
• Lubrication: Apply a light coat of grease to the inside of the receiver tube and any moving parts of your towing accessories to prevent rust and ensure smooth operation.
• Bolt Torque Check: After initial installation and periodically thereafter, re-check the torque of all mounting bolts to ensure they remain tightened to specifications.
