Installing a CURT trailer hitch is a surprisingly achievable task for the average DIYer, empowering you to tow with confidence and save on professional installation costs. By following a meticulously prepared guide and utilizing the correct tools, you can typically mount a CURT hitch in your driveway within a few hours, transforming your vehicle’s capabilities. This article provides a detailed, step-by-step approach, covering everything from identifying the correct hitch to torquing the final bolts, ensuring a safe and secure installation.
Choosing the Right CURT Hitch: Understanding Your Needs
Before even considering the installation process, it’s crucial to select the appropriate CURT hitch for your vehicle and towing requirements. CURT offers a wide array of hitches, categorized by their weight capacity, receiver tube size, and vehicle-specific design.
Determining Your Towing Capacity
The most critical factor in selecting a hitch is its Gross Trailer Weight (GTW) rating, which represents the maximum permissible weight of the trailer and its contents. Consult your vehicle’s owner’s manual for its maximum towing capacity. It’s imperative to choose a hitch with a GTW rating that meets or exceeds your vehicle’s capacity, but never exceeds the vehicle manufacturer’s recommendation. The hitch also has a Tongue Weight (TW) rating, which is the maximum downward force the hitch can handle. Typically, TW is about 10-15% of the GTW.
Identifying Your Vehicle’s Hitch Compatibility
CURT’s website offers a comprehensive vehicle search tool. Simply enter your year, make, and model to identify compatible hitches. Pay close attention to any notes regarding specific trim levels or model variations that may affect hitch compatibility. Some vehicles may require minor modifications, such as trimming the bumper fascia, for proper hitch installation.

The Installation Process: Step-by-Step Guide
This section outlines the general steps involved in installing a CURT trailer hitch. However, it’s absolutely crucial to refer to the specific installation instructions included with your particular hitch model, as variations may exist based on the vehicle and hitch design.
Step 1: Preparation
- Park your vehicle on a level surface. Engage the parking brake and, if possible, use wheel chocks for added safety.
- Elevate your vehicle. Use vehicle ramps or jack stands to raise the rear of the vehicle, providing ample clearance for working underneath. Always use jack stands for safety when working under a vehicle.
- Locate the mounting points. Refer to your hitch’s installation instructions to identify the designated mounting points on your vehicle’s frame. These are typically pre-drilled holes or weld nuts.
- Clean the mounting points. Use a wire brush or penetrating oil to remove any rust, dirt, or debris from the mounting points. This ensures a proper fit and secure connection.
Step 2: Hitch Placement and Alignment
- Carefully lift the hitch into position. It may be helpful to have an assistant during this step, especially with heavier hitches.
- Align the hitch mounting holes with the corresponding holes in the vehicle’s frame.
- Temporarily secure the hitch. Use the provided bolts and washers to loosely attach the hitch to the frame. Don’t tighten them completely at this stage.
Step 3: Securing the Hitch
- Double-check the alignment. Ensure the hitch is properly aligned with the vehicle’s frame and that all mounting holes are correctly aligned.
- Tighten the bolts to the specified torque. Use a torque wrench to tighten each bolt to the torque value specified in the installation instructions. This is a critical step to ensure a secure and safe installation. Tighten the bolts in a star pattern to distribute the force evenly.
Step 4: Wiring Installation (If Applicable)
- If your hitch requires wiring for trailer lights, follow the instructions provided with your CURT wiring harness. This typically involves connecting wires to the vehicle’s existing taillight wiring. Consider using a no-splice connector to avoid cutting into the vehicle’s wiring.
Step 5: Final Inspection and Cleanup
- Thoroughly inspect the installation. Double-check that all bolts are securely tightened and that the hitch is properly aligned.
- Remove the ramps or jack stands. Carefully lower the vehicle to the ground.
- Test the trailer lights (if applicable). Connect a trailer to your vehicle and verify that all the lights are functioning correctly.
