Setup and Installation
This CURT Class 1 hitch is designed for easy installation with a vehicle-specific fit, often requiring no drilling for select models. Refer to the included hardware and vehicle-specific instructions for detailed steps.
- Prepare the Vehicle: Park the vehicle on a flat, stable surface. Engage the parking brake. If necessary, raise the vehicle using a lift or jack stands for adequate clearance.

- Position the Hitch: Carefully lift the hitch into position, aligning the mounting holes on the hitch with those on the vehicle's frame.
- Secure with Hardware: Insert the provided fasteners through the aligned holes. Hand-tighten all bolts initially.

- Install Ball Mount: Insert the included ball mount into the 1-1/4 inch receiver tube. Secure it with a hitch pin and clip (not included). The ball mount can be oriented in either the rise or drop position to achieve level towing.

Operating Instructions
Once installed, your CURT trailer hitch is ready for use with compatible towing accessories.
- Attaching a Trailer: Insert the trailer ball (not included) into the ball mount and secure it. Connect the trailer coupler to the trailer ball, ensuring it is fully seated and latched. Attach safety chains from the trailer to the designated chain loops on the hitch.
- Connecting Accessories: For hitch-mounted cargo carriers, bike racks, or other accessories, insert the accessory shank into the 1-1/4 inch receiver tube and secure it with a hitch pin and clip.
- Weight Capacity: Always adhere to the maximum weight capacities: 2,000 lbs. Gross Trailer Weight (GTW) and 200 lbs. Tongue Weight (TW). Never exceed the lowest-rated component in your towing system.
- Driving with a Trailer: Drive cautiously, allowing for increased stopping distances and wider turns. Be aware of the added length and weight of your trailer.

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 welds and mounting points.
- Cleanliness: Keep the receiver tube free of dirt, debris, and moisture. The open-back receiver design facilitates easy cleaning.
- Corrosion Protection: The hitch features a dual-coat finish (liquid A-coat and black powder coat) for superior rust resistance. If the finish is scratched or damaged, touch up with appropriate paint to prevent corrosion.
- Fastener Check: Re-check the tightness of all mounting bolts periodically, especially after the first few uses and after long trips.

Troubleshooting
If you encounter issues with your CURT trailer hitch, consider the following common solutions:
- Hitch does not fit: Verify that the hitch model (116123) is compatible with your specific vehicle year, make, and model (Buick Encore GX or Chevrolet Trailblazer). Ensure no obstructions are present on the vehicle frame.
- Excessive play in receiver: Ensure the ball mount or accessory shank is fully inserted and secured with a properly sized hitch pin and clip. Some minor play is normal, but excessive movement may indicate an incorrect pin or worn components.
- Rust or corrosion: While the hitch has a durable finish, prolonged exposure to harsh conditions or physical damage can lead to rust. Clean affected areas and apply rust-inhibiting paint.
- Noise during towing: Check all connections, including the hitch bolts, ball mount, and trailer coupler, for proper tightness. Lubricate the trailer ball if squeaking occurs.
