RocketBox Pro Compact Rooftop Cargo Box
The RocketBox Pro is an extremely functional box that maximizes the entire 12 cubic feet of interior space. Despite its size, it has an impressive load capacity of 165 pounds and it can comfortably fit full camping gear for up to 2 campers.
Its modern design features a low profile setting with superb aerodynamics to reduce drag as much as possible. The Yakima carrier is manufactured from high-density ABS plastic for durability purposes.
The flawless push-button security system and front mounting hardware with quick release features are extremely useful while on the road.
Moreover, the box’s dual side opening system makes it one of the most practical and versatile compact cargo boxes on the market. The RocketBox Pro blends in style and ample storage, making it the best fit for your Lexus GS.
Thule Pulse Rooftop Cargo Box
Coming in second place is the carefully designed Thule Pulse roof top cargo box. Due to its sleek aerodynamic design it does not affect or overshadow the sportiness and aesthetics of your Lexus GS.
The ruggedly constructed cargo box provides plenty of space (14 cubic feet) for carrying gear/cargo. However, be careful not to exceed the 110-pound load capacity.
Installation of the Pulse can literally be done using one hand thanks to the Fast-Grip Quick-Mount system. It is recommended that the height off the crossbar be maintained at 16″ for a stable and smooth ride.
Additionally, an anti-theft system features a central locking mechanism equipped with a Thule Comfort Key for maximum protection of your belongings. Unlike the RocketBox pro, the Pulse opens only from the passenger side.
INNO BRA240BK Ridge Cargo Box
Our next pick is perfect for sedans. The BRA240BK is constructed using durable plastic material with a weather-resistant glossy black coat for an impeccable appearance. Its miniature 56.7 x 30.47 x 14-inch size is great for carrying skis and snowboards while leaving extra space on the roof to place other gear such as bikes or kayaks.
The aerodynamic design effectively reduces the drag, enhancing your fuel economy. While driving with the box attached, it is important to note that if you exceed 75 mph some noise will be emitted by the roof box. However, it’s nothing to worry about.
The INNO also uses the popular U-bolts for secure and reliable mounting. In addition, it makes installation fairly straightforward. The box also comes with two matching keys to ensure the lid is tightly shut, keeping your belongings safe from snoopers.
The INNO offers you the same superior functionality associated with Yakima and Thule labels at a slightly subsidized price range.
Thule SideKick Rooftop Cargo Box
The SideKick is one of Thule’s earlier models. However, due to its popularity it is still available to date. The box will provide you with an extra 8 cubic feet cargo volume. This might seem small; however trust me you don’t need a 22 cu ft. cargo box on top of your Lexus GS.
With a maximum load capacity of 75 pounds, almost 5 times its weight (16 pounds), the SideKick is one of the best roof boxes for your Lexus GS. An added advantage of using Thule products is the wide selection of compatible factory and aftermarket roof accessories. Easy fitting U-bolts and sturdy reinforcement plates secure the SideKick onto the rack.
Its forward position on the roof and being the smallest cargo box on this list ensures that it doesn’t come into contact with the rear hatch. Although mounting is simple, for optimal functionality, always ensure all the bolts are tightened, and the Sidekick is centrally placed on your roof bars.
Goplus Cargo Box
The Goplus is a medium-sized rooftop carrier that has a sleek aerodynamic design. It is also very spacious as t has a volume of 14 cu ft. and boasts 165 load. The glossy white coating makes the box resistant to UV rays. This not only increases its durability, it also reflects heat better providing for a cooler interior.
Measuring 63 x 31 x 15 inches, the Goplus cargo box has the right size and shape to be installed on your Lexus GS for a weekend getaway. In addition, it has 4 quick connect anchors that ensure it is mounted easily. At the same time, the double opening system makes loading and unloading easy as you can access the box from either side of your car.
Overall, the carrier’s specifications are designed to withstand heavy-duty usage in adverse weather conditions. So, if you’re an avid traveler, surfer, or cyclist, the Goplus carrier has you covered wherever you drift off to.
Conclusion
All the featured roof boxes come with limited lifetime warranties. Defective products are replaced or repaired without you incurring any cost. However, these warranties have diverse exclusions ranging from normal wear and tear to dents or deformities exerted after delivery.
That being said, proper adherence to the manufacturer’s instructions on mounting, usage, and maintenance. Lastly, you can be certain that no matter which product you go for, it will fit perfectly on your Lexus GS.
