Taking Adventure to New Heights: Our Experience with the 300lbs HmmtyRack Roof Rack Cross Bars
When it comes to maximizing space in your Jeep Grand Cherokee L or WL, few accessories make as big a difference as a quality roof rack system. Over the past month, we’ve been putting the HmmtyRack 300lbs Roof Rack Cross Bars thru their paces on various weekend adventures, and we’re excited to share our findings with fellow Jeep enthusiasts.
As dedicated outdoor adventurers with a growing collection of kayaks, camping gear, and sports equipment, we’ve always struggled with interior cargo space limitations. That’s why we were thrilled to test these aluminum crossbars specifically designed for the 2021-2026 Jeep Grand Cherokee L 3-Row and 2022-2026 Cherokee WL 2-Row models. With an impressive 300-pound capacity and security features that gave us peace of mind, these racks have transformed how we pack for our journeys. But do they truly deliver on their promises of easy installation, durability, and versatility? Let’s dive into our hands-on review.
Comprehensive Overview: A Hands-On Look at the 300lbs Jeep Grand Cherokee Roof Rack System

After putting HmmtyRack’s aluminum roof rack system through its paces on our 2022 Grand Cherokee WL, we’re genuinely impressed with its blend of strength and lightweight construction. The crossbars are crafted from high-grade aluminum that’s approximately 30% lighter than steel alternatives, yet they don’t compromise on durability. With a remarkable weight capacity of 300lbs (136kg), these racks easily accommodated everything from our rooftop cargo box to kayaks during weekend adventures. The security features are particularly noteworthy-the included locking mechanism provided peace of mind when parking in public areas, ensuring our gear remained secure. Installation proved straightforward, taking less than 20 minutes with just a basic screwdriver, though we recommend paying close attention to the instruction manual tucked at the bottom of the packaging.
The thoughtful design elements of this roof rack system truly stand out during real-world use. We appreciated how the front crossbar is purposefully longer than the rear to properly accommodate the vehicle’s roof contours-a detail that results in better aerodynamics and reduced wind noise at highway speeds. The versatility of these racks has transformed our outdoor adventures, supporting a variety of attachments for:
- Water sports equipment (kayaks, canoes, paddleboards)
- Winter gear (skis, snowboards)
- Cargo carriers (boxes, bags, baskets)
- Cycling equipment (multiple bike mounts)
| Feature | Benefit |
|---|---|
| Aluminum Construction | Lightweight yet stronger than steel |
| Locking Mechanism | Enhanced security for gear |
| 300lbs Capacity | Accommodates multiple large items |
| Tool-Free Installation | Quick setup without drilling |

Real-World Performance: How These Racks Handle Kayaks, Cargo, and Snowboards

We put these aluminum roof racks through their paces, and the impressive 300 lbs capacity isn’t just marketing hype-it’s genuinely reliable in real-world conditions. During our testing trips, we loaded two full-sized kayaks (approximately 120 lbs combined with gear) and still had ample capacity left. The lightweight aluminum construction provides superior strength without adding unnecessary weight to your Jeep’s roof. Unlike steel alternatives, these crossbars didn’t create noticeable wind noise even at highway speeds, maintaining a quiet cabin environment. The locking mechanism proved especially valuable during our overnight stops, keeping our adventure gear secure while we camped.
The versatility of these racks truly shines when adapting to different cargo needs. We’ve used them for transporting:
- Three snowboards with bindings (secured using standard snowboard attachments)
- A roof cargo box plus fishing rods
- Two mountain bikes using aftermarket bike mounts
- A 10-foot ladder and construction materials
The front crossbar’s increased length perfectly accommodates wider items, while the robust construction prevents any concerning flex or bounce, even on rough forest service roads. For families juggling multiple outdoor hobbies, these racks eliminate the need to choose which gear to bring-you can easily transport everything from camping equipment to water sports gear concurrently.

Customer Reviews Analysis

Customer Reviews Analysis
After thoroughly testing these roof rack cross bars ourselves, we wanted to see how other Jeep owners’ experiences compared to our findings. We analyzed dozens of verified customer reviews to provide you with a comprehensive overview of what real users think about this affordable roof rack solution.
Installation Experience
The overwhelming consensus among customers is that these cross bars offer remarkably easy installation. Multiple reviewers mentioned completing the setup in just 10 minutes, with one specifically noting “Perfect fit 2021 grand cherokee. 10 minute install.” Though, we did notice one minor issue raised by a customer who found that “the supplied Allen wrench was too wide to fit between my roof and the rack to tighten the screws.” Fortunately, they easily resolved this by using their own Allen wrench.
Fit and Compatibility
These cross bars appear to deliver excellent compatibility across various Jeep models. Reviewers consistently praised the precise fit for the Grand cherokee, with comments like “Fits great and looks great on vehicle” and ”Fit perfect on mi grand cherokee WL 2022.” Interestingly, one customer even successfully adapted these racks to their ”2021 CRV flush mount rail,” suggesting versatility beyond the advertised Jeep compatibility.
| Aspect | Positive Feedback | Improvement Areas |
|---|---|---|
| Installation | Quick (10 min), straightforward, well-engineered | Allen wrench accessibility in tight spaces |
| Appearance | Looks good on vehicle, solid appearance | Some find the narrow position on rails unappealing |
| Value | Exceptional value, savings up to $400 over alternatives | lock covers would improve design |
Build Quality and Value
We were particularly impressed by comments regarding the build quality and value. multiple customers described the racks as “solid” and “well engineered.” One keen reviewer proclaimed they “work like a charm, and at the fraction of the cost of snazzy name-brand models,” while another exclaimed they “Saved me about $400!” This confirms our own assessment that these cross bars offer exceptional value without compromising on quality.
Design Considerations
Design feedback was generally positive, though with some mixed opinions. While most reviewers thought the racks looked good on their vehicles, one customer noted: “Fine racks for what they are but I hate the look (not this products fault, it’s the rail system).” The same reviewer mentioned that “The racks attach on the inside of the rail and rise up from the inside of the rail so they sit very narrow on the roof.” This narrow positioning might not appeal to everyone’s aesthetic preferences.
A minor design improvement suggestion came from one customer who mentioned “Only room for improvement coudl be the addition of a plug over the locks” – a detail we also noted in our testing.
Performance
While fewer customers commented specifically on long-term performance, those who did were satisfied. One reviewer confirmed they are ”road tested with a sky box and other contraptions,” indicating reliable performance under actual use conditions. Several customers expressed confidence in the product’s durability and functionality.
customer reviews overwhelmingly validate our own positive experience with these roof rack cross bars. with easy installation,solid construction,and tremendous value compared to premium alternatives,it’s clear why these racks have earned such positive feedback from the Jeep community.
Pros & cons

Pros & Cons
Pros:
- Impressive Load Capacity: The 300lbs (136kg) weight limit exceeded our expectations, allowing us to easily transport kayaks and camping equipment simultaneously during our weekend tests.
- Lightweight Design: The aluminum construction makes these crossbars noticeably lighter than steel alternatives we’ve tested, which made installation less cumbersome.
- Secure Locking Mechanism: We appreciated the included locks that gave us peace of mind when leaving our gear mounted while making pit stops during our road trip.
- Tool-Free installation: We managed to install the entire system in under 15 minutes with just a screwdriver,making the setup process refreshingly straightforward.

- Versatile Compatibility: Works with multiple Jeep models (2021-2026 Grand Cherokee L and 2022-2026 Cherokee WL), providing flexibility for different vehicle owners.
Cons:
- Packaging Issues: We nearly missed the installation instructions and keys that were stuck to the bottom of the box - better packaging association would prevent potential frustration.
- Wind Noise: At highway speeds above 65mph, we noticed a slight whistling sound that wasn’t present before installation.
- Vehicle-Specific Load Limits: While the rack supports 300lbs, we had to consult our vehicle manual to confirm our Jeep’s actual roof weight capacity was lower at 165lbs – this could confuse some buyers.
- Different Bar lengths: The front bar being longer than the rear wasn’t immediately obvious from the packaging, causing a moment of confusion during our initial installation attempt.
- No Integrated Tie-Down Points: We found ourselves wishing for built-in attachment points for securing straps when transporting irregular items.

| Build Quality | 4.5 | Solid aluminum construction with good finishing |
| Ease of Installation | 4.0 | Quick process, minor documentation issues |
