The cost to install a hitch on a Subaru is typically $250 to $700 for an aftermarket receiver hitch with professional installation, and often $600 to $1,100 or more for a dealer-installed factory (OEM) hitch. Doing it yourself costs only the parts, usually about $150 to $450. Prices vary by model, hitch type, wiring and local labor rates, so confirm with a written quote.

Why Add a Hitch to a Subaru?
A receiver hitch lets you use a hitch-mounted bike rack or cargo carrier, tow a small trailer, or add a recovery anchor point for light use. A rack on the hitch keeps bikes off the roof, so you do not have to lift them overhead. Whatever you attach, stay within the lowest of your hitch, vehicle and accessory ratings.
Hitch Classes: Which Fits Your Subaru?
| Class | Receiver | Typical rating | Good for |
|---|---|---|---|
| Class I | 1.25 inch | Up to about 2,000 lbs trailer weight | Light bike racks and cargo carriers |
| Class II | 1.25 inch | Up to about 3,500 lbs trailer weight | Small utility trailers, 2-3 bike racks |
| Class III | 2 inch | Commonly up to about 5,000 lbs weight-carrying, depending on the maker | Platform and e-bike racks, larger trailers (if the vehicle allows) |
Many heavy bike racks need a 2-inch receiver, so a Class III hitch is a common choice for Outback, Forester and Ascent owners. Always check the hitch maker’s fit guide for your exact model and year.
Subaru Towing Capacity: Check Before You Buy
The hitch does not raise your vehicle’s towing limit. The Ascent is rated to tow up to 5,000 lbs when properly equipped, while many other Subaru models are rated much lower. Ratings differ by model, engine, trim (including Wilderness versions) and year, so read your owner’s manual or ask a Subaru retailer before towing.
Subaru notes that the 2026 Outback Premium includes a removable rear bumper cover section intended to make trailer hitch installation easier, which can reduce trimming work on some trims.
What Changes the Price
- Bumper trimming: Concealed or OEM-style hitches on newer Subarus may require removing or trimming the rear fascia, which adds labor time.
- Aftermarket vs. OEM: Aftermarket hitches mount to the frame and cost less. OEM hitches are designed for the model and are usually installed by the dealer, at a higher price.
- Wiring: A 4-pin harness powers lights. Trailers with electric brakes need a 7-pin connector and a brake controller. Brake rules vary by state.
- Installer: Dealers, national hitch installers and independent shops charge different labor rates.
DIY or Professional Installation?
| Factor | DIY | Professional |
|---|---|---|
| Cost | Parts only, about $150 to $450 | About $250 to $1,100+ |
| Time | Several hours for a first-timer | Often 1 to 2 hours for a basic bolt-on |
| Tools | Torque wrench, socket set, jack stands, possibly exhaust pliers | Lift and shop tools |
| Risk | Wrong torque or loosened exhaust hangers if not done carefully | Lower; ask about a labor warranty |
A DIY install usually means lowering the exhaust slightly, fishing bolts through frame holes, and tightening to the maker’s torque specification. Follow the instructions that come with your hitch. If you do not have a torque wrench and jack stands, use a professional.
Where to Get a Subaru Hitch Installed
- Subaru dealer: Installs OEM hitches and usually offers the highest price and a factory-matched fit.
- National hitch installers (for example U-Haul): Often the lowest labor cost for aftermarket hitches. U-Haul lists receiver hitches at about $195 to $215 in published guides.
- Independent shops: Competitive labor, especially if you supply the hitch.
How to Save Money
- Compare at least three quotes for the same hitch class and wiring.
- Buy only the wiring you need. A bike rack does not need trailer wiring.
- Ask whether the shop will install a hitch you buy yourself, and at what labor rate.

Frequently Asked Questions
Does installing a trailer hitch void my Subaru warranty?
Not automatically. Under the U.S. Magnuson-Moss Warranty Act, an aftermarket part alone does not void a vehicle warranty. If the hitch or towing beyond the rated limit causes damage, the manufacturer may deny coverage for that repair. Check your warranty booklet.
What is the best hitch for a Subaru Outback or Forester?
Most owners choose a 2-inch Class III receiver because it fits heavy platform bike racks and cargo carriers. Use the hitch maker’s fit guide for your exact model and year, and stay within your vehicle’s towing rating.
Do I need wiring if I only use the hitch for a bike rack?
Usually no. Wiring is needed when towing a trailer with lights or brakes. Some bike racks that block your taillights may need a light kit, so check the rack instructions.
How long does professional hitch installation take?
A basic bolt-on usually takes about one to two hours. Jobs that need bumper trimming or extra wiring can take longer.
Conclusion
Plan on about $250 to $700 for a professionally installed aftermarket hitch and $600 to $1,100 or more for a dealer OEM hitch. Choose the class by what you plan to carry, confirm your Subaru’s towing rating, and compare itemized quotes before you buy.
