I’ve run a Yakima Skybox on my roof for three years. Works great, until you’re 5’4” and heaving a 40-pound bag over your head in a parking lot at 6am. So when hitch-mounted alternatives started coming up in my searches, the Yakima EXO GearLocker kept showing back up. At $648.95, it’s not cheap. But neither is a chiropractor. Here’s the honest version.
What Is the Yakima EXO GearLocker?
The EXO GearLocker is a hard-shell hitch cargo box built specifically for Yakima’s EXO system — either the EXO SwingBase or EXO TopShelf. Not a standalone product. You need the base system first, which is the thing to know before the price tag gets you excited.
It mounts at hitch height instead of on your roof, which changes the whole experience. No ladder, no reaching overhead, no aerodynamic penalty on the highway. The box swings away from the vehicle so the tailgate still opens — that’s the entire point of the EXO system, really.

Who Actually Buys This Thing
Scroll through the reviews and a pattern shows up fast: Subaru owners, dog owners, people who’ve already maxed out a rooftop box and don’t want a bigger car just for storage. One reviewer put it plainly — worth it, and a lot cheaper than a new car.
This appeals to a specific buyer: someone already in the Yakima EXO ecosystem who wants more capacity without piling more onto the roof. Also makes sense if reaching the roof is genuinely a problem — height, a bad back, whatever — or if you’re loading and unloading gear constantly on the road.
Installation
This is where it earns real points. Tool-free. If the SwingBase or TopShelf is already on your vehicle, the GearLocker just drops in. Several reviewers say it goes on in minutes, and it’s key-locked so nobody’s walking off with it.
One owner with a 2025 Sprinter said it worked great out of the box. A Subaru owner mentioned doing the whole install solo, which matters if you’re not always traveling with extra hands.
The swing-away design keeps the tailgate accessible after mounting — open the box, grab what you need, swing it back. If you’ve ever fought your way into a loaded wagon with a hitch basket blocking the door, you know exactly why this matters.
What 10 Cubic Feet Actually Feels Like
Ten cubic feet isn’t huge. A typical rooftop box like the Yakima SkyBox NX 18 holds 18. You’re trading volume for accessibility and a lower center of gravity, not getting both.
In real terms, 10 cubic feet covers:
- A weekend’s luggage for two
- Camping overflow — sleeping bags, tent poles, cooking gear
- Grocery runs when the trunk’s already full
- Golf bags, which one reviewer specifically mentioned
- Crates and supplies for working dogs
One owner runs this alongside a roof-mounted Skybox — the GearLocker handles daily overflow, the rooftop box takes the bulky stuff. That combination actually makes sense if you’re hauling a lot of gear on a regular basis.
The Honest Downsides
The reviews are pretty candid about what’s wrong with it, so no point softening it.
It’s plastic, and it feels like it. At least one reviewer was surprised how thin the material feels for the price. The shell is impact-resistant ABS and polypropylene — fine against road debris and weather — but if you’re expecting something that feels like a tank, you won’t get that here. Someone pointed out you could probably cut through it with a knife, which, to be fair, is true of most plastic cargo boxes.
The lid doesn’t open all the way. One reviewer flagged this directly — the lid supports don’t open far enough, which gets annoying fast when you’re loading something two-handed. It’s also riveted rather than bolted, something a few buyers brought up as a long-term durability concern.
Contents get hot in direct sun. Hitch height means more sun exposure than a rooftop box, so heat-sensitive items aren’t a great fit for summer storage in here.
Backup sensors can get affected. One detailed review mentioned the EXO sitting low enough that it doesn’t block their SUV’s lights, which is a plus, but it did interfere with backup sensors. Worth testing on your own vehicle before committing.
Key management is a minor annoyance too. A Canadian reviewer ended up with four different keys across two GearLockers — Yakima doesn’t automatically match keys across units. Ask if matching key sets are available before you buy a second one.

Hard Shell vs Soft Shell: Which Makes Sense Here
If you’re torn between this and a soft-sided hitch bag, the math isn’t what it looks like at first glance. Soft bags cost less and often hold more, but they’re not meaningfully lockable and offer no impact protection. The hard shell and the lock are really what you’re paying for here.
If all you need is weather protection and volume, a waterproof rooftop cargo carrier bag at a fraction of the price might suit you better. The GearLocker is for people who specifically want hitch-mount convenience and don’t want a soft bag.

EXO GearLocker vs. Competitors
| Feature | Yakima EXO GearLocker | StowAway Max Hitch Box | Generic Hitch Basket + Bag |
|---|---|---|---|
| Capacity | 10 cu ft | ~18 cu ft | 20-25 cu ft |
| Price | ~$649 | ~$1,198 | $150-300 |
| Hard Shell | Yes | Yes | Basket only |
| Swing-Away | Yes (with EXO base) | No | No |
| Tool-Free Install | Yes | Varies | No |
| Locking | Yes | Yes | No |
| Requires Base System | Yes (EXO) | No | No |
The StowAway Max costs nearly double and skips the swing-away tailgate access. Generic hitch baskets are cheaper and hold more, but you’re giving up security and weather protection to get there. The GearLocker sits in its own middle ground — pricier than a basket, less capacity than a StowAway, but with features neither of the others offers.
Who Should Buy It
Buy it if:
- You already have, or plan to get, the Yakima EXO SwingBase/TopShelf system
- You want secure, lockable, hard-shell storage at hitch height
- Reaching a rooftop box is genuinely difficult for you
- You load and unload often and want easy access without a ladder
- You’ve already got a rooftop box and just need more room
Skip it if:
- You don’t have the EXO base system — the added cost makes this a lot more expensive than it looks
- You need more than 10 cubic feet
- Price is the deciding factor — a rooftop cargo bag gets you more volume for less
- You want serious theft deterrence — it’s plastic, so don’t store anything irreplaceable in it

Final Verdict
The Yakima EXO GearLocker is built well for a narrow use case. The swing-away design is genuinely useful, installation is as easy as Yakima says, and 78% of the 92 reviews land at five stars.
The complaints are real but livable — the plastic feels light for the money, the lid’s support arms could open further, and you’re tied into the EXO ecosystem whether you like it or not. None of that rules it out for the right person.
If you’re already running Yakima’s EXO base and want lockable cargo space at hitch height without a ladder involved, this does exactly what it says.
