You can buy a tow bar, also known as a trailer hitch, from several types of retailers, both online and in physical stores. The best place depends on whether you need professional installation or plan for a DIY project. For a full-service experience, including expert advice and installation, specialty automotive stores like U-Haul, Pep Boys, or local hitch shops are your top choices. For the widest selection and competitive pricing, major online retailers like Amazon, etrailer.com, and AutoZone.com are excellent options, but you'll need to handle installation yourself or find a local mechanic.
The most critical first step is identifying the correct tow bar class and fit for your specific vehicle. Tow bars are categorized by weight capacity (Class I through V) and must be designed for your car's exact make, model, and year to ensure safe operation.
| Tow Bar Retailer Type | Key Features | Examples | Best For |
|---|---|---|---|
| Specialty Hitch Shops | Expert installation, custom fabrication, warranty on labor | U-Haul, Local Hitch Centers | First-time buyers, complex installations, guaranteed work |
| Auto Parts Stores | Click-and-collect convenience, basic selection | AutoZone, Advance Auto Parts | DIYers who know their exact part number |
| Major Online Retailers | Vastest selection, user reviews, competitive prices | etrailer.com, Amazon, CARiD.com | Savvy shoppers comparing options and prices |
| Big-Box Retailers | Basic, low-cost hitches for common vehicles | Walmart, Target | Budget-conscious buyers with common vehicle models |
Before purchasing, check your vehicle's Gross Trailer Weight (GTW) and Tongue Weight ratings, which are listed in your owner's manual. This ensures the tow bar you select does not exceed your car's engineered towing capacity. For most people, a professional installation is recommended to guarantee the electrical wiring for trailer lights is correctly integrated and the hitch is securely mounted to the vehicle's frame.

Honestly, I just go to U-Haul. I’m not a car guy, and the last thing I want is to bolt something important to my SUV incorrectly. I walked in, told them what I drive, and they showed me the exact hitch I needed. They installed it in under an hour while I waited. It cost a bit more than just the part, but for me, the peace of mind knowing it was done right was totally worth it. No guesswork, no hassle.

I’m all about online for this. Sites like etrailer.com are fantastic because they have videos showing the installation on your exact car model. You put in your vehicle info, and it only shows you hitches that will fit. I bought mine there, watched the video a couple of times, and installed it myself in the driveway on a Saturday morning. Saved a ton on labor and learned something new. Just make sure you have a good jack and torque wrench.

Don't forget about the scrapyard or a junkyard that specializes in auto parts. If you're driving an older vehicle and need a simple tow bar for light duty, you might find a used one for a fraction of the cost. You'll need to know how to identify a good, uncracked unit and how to remove it, but it's a viable option for the budget-minded and mechanically inclined. Always inspect the mounting points for rust or stress cracks before you buy.

My first stop is always a dedicated local truck and hitch accessory shop. These places are run by experts who live and breathe towing. They can give you advice you won't get from a big-box store clerk, like which hitch receiver design is best for your specific usage or how to properly distribute weight. Supporting a local business is a plus, and their installation is often top-notch because it's their specialty. They can also recommend the right ball mount and wiring harness.
