Installation Guidelines

The CURT 13099 trailer hitch is designed for a custom, vehicle-specific fit on select model years of older Ford, GMC, and Chevrolet pickup trucks. It is crucial to consult the detailed installation instructions provided with your specific hitch package for accurate and safe installation. General steps typically include:

1. Preparation: Ensure the vehicle is on a level surface and properly supported. Gather all necessary tools and hardware.
2. Clearance: Temporarily lower or remove the spare tire if it obstructs the installation area.
3. Positioning: Carefully position the hitch assembly against the vehicle's frame rails, aligning the mounting holes.
4. Securing: Insert the provided bolts and hardware through the frame and hitch mounting points. Hand-tighten all fasteners.
5. Final Tightening: Refer to the specific torque specifications in your instruction manual to tighten all bolts securely.
6. Reinstallation: Reinstall any components removed during the process, such as the spare tire.

Note: Some installations may require drilling additional holes in the vehicle frame. Always follow the manufacturer's instructions for drilling and bolt tightening. Professional installation is recommended if you are unfamiliar with vehicle modifications.

Operating Instructions

Once installed, the CURT 13099 Class 3 Trailer Hitch provides a secure connection point for towing. Adhere to the following guidelines for safe operation:

• Hitch Ball and Mount: Use a hitch ball and ball mount compatible with a 2-inch receiver and rated for your towing requirements. Ensure the hitch ball is properly torqued to the ball mount.
• Trailer Connection: Securely attach the trailer coupler to the hitch ball. Engage the coupler latch and insert a safety pin or lock.
• Safety Chains: Always cross safety chains under the trailer coupler and attach them to the designated chain loops on the hitch. This prevents the trailer from separating completely if the coupler fails.
• Wiring: Connect the trailer's electrical wiring to the vehicle's towing harness to ensure proper function of trailer lights and brakes.
• Weight Distribution: For heavier loads or to achieve level towing, this hitch is compatible with a weight distribution system. Follow the weight distribution system's instructions for proper setup.
• Load Limits: Never exceed the maximum towing capacities of the hitch, your vehicle, or any other towing component.
• Inspection: Before each tow, inspect the hitch, ball mount, hitch ball, safety chains, and wiring for any signs of wear, damage, or loose connections.

Maintenance

Proper maintenance will extend the life and ensure the safe operation of your CURT trailer hitch.

• Regular Inspection: Periodically inspect the hitch for any signs of rust, cracks, bends, or other damage. Pay close attention to weld points and mounting hardware.
• Cleanliness: Keep the receiver tube free of dirt, debris, and rust. This ensures easy insertion and removal of ball mounts and accessories.
• Finish Protection: The hitch is protected with a co-cured liquid A-coat and black powder coat finish, designed for superior resistance to rust, chipping, and UV damage. Avoid using harsh chemicals or abrasive materials that could compromise this finish.
• Hardware Check: Regularly check all mounting bolts and nuts to ensure they remain tightened to the manufacturer's specified torque settings.

Troubleshooting

This section addresses common issues that may arise with trailer hitch usage. For complex problems, consult a qualified professional.

• Difficulty Installing: If the hitch does not align with the vehicle's frame, double-check the vehicle compatibility information. Ensure no obstructions are present. Some installations may require minor adjustments or drilling, as specified in the detailed instructions.
• Loose Connections: If the hitch feels loose after installation, re-check all bolts and ensure they are torqued to the correct specifications. Over time, bolts can loosen due to vibration; regular checks are essential.
• Excessive Sway During Towing: This is often related to improper load distribution on the trailer or insufficient tongue weight. Ensure the trailer is loaded correctly, and consider using a weight distribution hitch if your setup allows and requires it.
• Rust or Corrosion: While the hitch has a protective coating, prolonged exposure to harsh conditions or damage to the finish can lead to rust. Clean affected areas and apply a rust-inhibiting paint if necessary.

Important Safety Information

• Always adhere to the towing capacity limits of your vehicle, the trailer hitch, and the trailer itself. Use the lowest rating as your maximum.
• Ensure all towing components (hitch, ball mount, hitch ball, pins, clips, safety chains, wiring) are in good working order and properly secured before each trip.
• Distribute the trailer load evenly, with approximately 10-15% of the total trailer weight on the tongue for conventional trailers.
• Drive cautiously when towing. Allow for increased stopping distances and wider turns.
• Regularly check tire pressure on both the tow vehicle and the trailer.
