300 lb vs 330 lb Cargo Bars
Load capacity
The KINGGERI cross bars offer a higher maximum load capacity of 330 lbs (150 kg), while the FengYu bars are rated for 300 lbs (130 kg). This 30 lb difference matters if you plan to carry heavier items like large roof boxes or bulky gear. Both brands use aircraft-grade aluminum to support these weights, ensuring structural integrity. You should always distribute weight evenly across both bars to stay within the limit. If your typical load is under 300 lbs, either option works. However, for heavier cargo, the KINGGERI model provides a safer margin. Always check your vehicle's own roof rack limits, as they may be lower than the bars' ratings.
Compatibility
These bars are vehicle-specific and not universal. The FengYu bars are designed exclusively for the 2022-2027 Kia Carnival and Carnival Hybrid with raised side rails. In contrast, the KINGGERI bars fit the 2019-2026 Subaru Ascent with raised side rails. You cannot swap these between vehicles. Each brand offers variations for other cars, but you must select the exact model for your car. The FengYu fits a minivan, while the KINGGERI fits a midsize SUV. Using the wrong bar can damage your vehicle or fail to secure properly. Check your roof rail type and model year before buying. Do not assume compatibility based on brand alone.
Build and security
Both bars include metal mechanism lock systems to prevent theft. The FengYu bars use high-grade plastic for the clamps, which adds durability against corrosion. The KINGGERI bars use high-grade aluminum for the brackets, offering a more robust metal-to-metal connection. Both designs are low-profile and streamlined to reduce wind noise at high speeds. The FengYu bars weigh 10 pounds, while the KINGGERI bars weigh 14 pounds. The heavier KINGGERI bars may feel more solid, but the FengYu bars are lighter to handle. Both include tie-down loops on the base feet or brackets to secure cargo with ropes up to 1/4 inch wide.
Dimensions and fit
The physical dimensions differ slightly between the two products. The FengYu bars measure 36 inches in length, 3.8 inches in width, and 5.8 inches in height. The KINGGERI bars are slightly longer at 37 inches, wider at 4 inches, and taller at 6 inches. The KINGGERI front bar is longer than the rear bar to accommodate the Subaru Ascent's shape. The FengYu bars are a single uniform length. These size differences affect how much roof space you have for a cargo box. Taller bars may create more drag, but both are designed to minimize wind resistance. Choose the size that best fits your vehicle's roof width and your cargo box dimensions.
Installation
Both bars feature clamp-on installation that requires no drilling or permanent modification to your vehicle. The FengYu bars mount directly onto existing roof rails following marked instructions. The KINGGERI bars come with necessary installation tools and are labeled front and back to simplify assembly. You can assemble and disassemble the KINGGERI bars in a few minutes. The FengYu bars also emphasize easy installation without modification. Both designs allow you to adjust the width to fit your specific vehicle's rail spacing. This tool-free approach makes switching bars between vehicles possible if you have compatible models. Follow the manufacturer's torque specifications to ensure a secure fit.
Which crossbar fits your needs
Subaru Ascent owners needing max load
The KINGGERI bars support 330 lbs, offering 30 lbs more capacity than the FengYu alternative. This higher limit suits heavier gear. The bars fit Subaru Ascent models from 2019 to 2026. Their 37-inch length and 4-inch width provide a stable platform for bulky items.
Kia Carnival owners with raised rails
This FengYu set is designed specifically for Kia Carnival and Hybrid models from 2022 to 2027. It mounts directly onto existing raised side rails without drilling. The 300 lb capacity handles most cargo needs. The 36-inch length fits the vehicle roof profile securely.
Drivers prioritizing lighter weight bars
The FengYu cross bars weigh 10 pounds, which is 4 pounds lighter than the KINGGERI bars. This reduced weight may help with fuel efficiency and ease of handling during installation. Both use aluminum construction, but the FengYu design is slightly shorter and narrower for a streamlined look.
