Can you add a Trailer Hitch to a Subaru Ascent?

Yes. You can add a trailer hitch to a Subaru Ascent, and with the proper equipment you can tow up to 5,000 pounds.

The Ascent supports hitch installations through factory towing packages or reputable aftermarket options. The best path depends on your towing plans, budget, and whether you want factory guarantees or broader aftermarket choice. This article walks you through the options, what to buy, and key safety considerations.

OEM towing package options

For the simplest path with the strongest warranty and fit, many owners choose a dealer-installed towing package. Availability and exact contents vary by model year and trim, so check with a Subaru retailer for your vehicle.

• 2-inch Class III hitch receiver specifically designed for the Ascent


• Trailer wiring harness to connect trailer lights (configurations typically include 4- or 7-pin connectors)


• Vehicle-specific mounting hardware and installation service


• Possible inclusion of a trailer brake controller or related towing electronics, depending on year and package

Choosing the OEM towing package typically preserves factory warranty coverage and ensures the hitch and wiring are installed to Subaru specifications.

Aftermarket hitch options

If you prefer a different route or a potential cost savings, you can install a third-party Class III or IV hitch that fits the Subaru Ascent. Make sure the kit is compatible with your exact year and model, and have installation performed by a qualified technician if you’re not comfortable with hitch mounting.

• 2-inch Class III or IV hitch rated to handle up to 5,000 pounds gross trailer weight (verify rating for your year/model)


• Wiring harness for trailer lights (4-pin or 7-pin, with adapters as needed)


• Mounting hardware and any vehicle-specific fit adjustments


• Consideration of warranty implications and whether dealer reprogramming or updates are needed

Aftermarket options offer flexibility and potential savings, but ensure compatibility, proper installation, and clear warranty terms before purchase.

Important towing considerations

Regardless of which route you choose, plan around weight ratings, braking needs, and legal requirements to tow safely.

1. Check the owner’s manual for the Ascent’s tow ratings (GVWR, GCWR) and tongue weight, and confirm the exact limit for your year and engine.


2. Determine if a trailer brake controller is required or recommended for your trailer and install one if needed.


3. Ensure a proper electrical connection and test trailer lights and brakes before towing.


4. Consider using a weight-distributing hitch for heavier loads to improve stability and control.


5. Follow local regulations regarding trailer towing, including brakes, licensing, and insurance requirements.

Consult your Subaru dealer or a certified installer if you’re unsure about ratings, wiring, or brake-controller needs before hitting the road.

Summary

In short, adding a trailer hitch to a Subaru Ascent is a common and feasible upgrade. You can pursue an OEM towing package through a Subaru dealer or opt for a reputable aftermarket hitch, with a maximum towing capacity up to 5,000 pounds when properly equipped. Plan for correct wiring, potential brake control, and adherence to weight limits, and verify details for your exact year and trim with a local dealer or installer.
