What size hitch does a Subaru Outback have?
The current Subaru Outback uses a 2-inch hitch receiver (50 mm) on most modern models. Some older generations used smaller sizes, so verify your specific year if you are dealing with a vintage Outback.
Hitch size matters for towing capacity and for compatible accessories such as bike racks, cargo carriers, and trailers. This article explains the standard size on recent Outbacks, how to confirm the size on your exact model, and practical tips for choosing the right hitch setup.
Standard hitch size on current Outback models
Here are the key facts you’re likely to encounter if you own or are considering a current-generation Outback. The list focuses on the most common configuration and what it means for towing and accessories.
- Opening size: 2 inches (50 mm) square receiver
- Hitch class: Class III (typical for a 2" receiver), suitable for a broad range of towing and accessory setups with the correct mounting hardware
- Towing capacity: Engine- and equipment-dependent; roughly 2,700 pounds for the 2.5-liter models and up to 3,500 pounds in higher-spec configurations or certain years, as specified in the owner's manual
- Accessories and compatibility: Most 2" receivers accept standard ball mounts, bike racks, and cargo carriers, but always verify weight ratings and wiring requirements for towing
In practice, a 2-inch hitch is the standard for modern Outbacks, and you should consult your manual to confirm the exact rating for your trim and year before towing or purchasing accessories.
How to verify your exact hitch size on your Outback
To avoid buying the wrong hardware, use these steps to confirm the receiver size on your specific vehicle.
- Check the owner's manual or Subaru's official spec sheets for your model year; look for details on the trailer hitch or receiver size
- Inspect the hitch opening visually; a measurement around 2 inches (50 mm) indicates a 2" receiver; a much smaller opening suggests an alternative size
- Look for stamped markings on the hitch itself (inside the opening or on the cross member) indicating "2", "50 mm", and "Class III"
- Measure the inner width with a ruler or tape if markings are unclear; the inner width typically corresponds to the receiver size
- If in doubt, contact a Subaru dealer or service center with your VIN to confirm the recommended hitch size for your exact vehicle
- When you confirm, ensure you pair the receiver with appropriate tow components (ball mount, hitch ball, wiring harness) rated for your towing needs
Verifying the hitch size helps you avoid incompatible accessories and ensures you have the correct safety ratings for towing and carrying gear.
Summary
In today’s Subaru Outbacks, the standard hitch opening is 2 inches, and it is classified as a Class III receiver on most recent models. Always verify your exact model year and engine configuration in the owner's manual or with a dealer, as there are variations across generations. With the right 2" hitch, you can safely tow within the vehicle’s rated limit and attach common hitch-mounted accessories.
