You will find choices ranging from compact 8 cu ft boxes to larger 18 cu ft carriers. Some models feature dual-side opening for easier access, while others prioritize higher weight limits or different dimensions. Use the detailed specs below to match the cargo box to your roof rack and storage requirements.
How alternatives compare to Maxsa
GarveeTech 12 cu ft Dual-Side Opening Roof Box
The GarveeTech 12 cu ft box offers dual-side opening access, unlike the Maxsa Innovations model which uses a single rear hatch. This feature lets you load gear from either side of your vehicle, a practical advantage in tight parking spots. However, it provides less total volume at 12 cubic feet compared to the Maxsa’s 17 cubic feet. It shares the same 165 lb load capacity but weighs slightly more at 39 pounds versus 35.3 pounds. Choose this if side access matters more than maximum storage space.
JEGS 18 cu ft Rooftop Cargo Carrier
The JEGS 18 cu ft carrier provides more interior volume than the Maxsa Innovations 17 cu ft box, offering 18 cubic feet for larger items. It also features a dual-side opening design for easier access. The trade-off is a lower weight limit of 110 lbs, which is significantly less than the Maxsa’s 165 lb capacity. It is longer at 61.3 inches and slightly lighter at 35.5 pounds. Pick this option if you need extra room for bulky gear and do not plan to carry heavy loads.
PM Performotor 11 cu ft Hard Shell Cargo Box
The PM Performotor 11 cu ft box is smaller than the Maxsa Innovations model, offering 11 cubic feet instead of 17. This makes it better for lighter loads and smaller vehicles. It lacks a specified load capacity in the data, whereas the Maxsa supports 165 lbs. The PM Performotor is shorter at 53 inches and has a similar height of 15 inches. It is a compact choice for drivers who prioritize a lower profile and reduced wind resistance over maximum carrying capacity.
JEGS 18 cu ft Hardshell Rooftop Carrier
The second JEGS 18 cu ft hardshell box matches the volume of the other JEGS model but differs in dimensions. It is 57 inches long and 17.8 inches high, making it taller than the Maxsa Innovations 16.1-inch height. This increased height may affect aerodynamics compared to the Maxsa’s streamlined design. It shares the dual-side access feature but does not list a specific load capacity in the provided data. Choose this if you need high capacity and side access, and can accommodate a taller profile on your roof rack.
Goplus 14 cu ft Dual-Side Opening Roof Box
The Goplus 14 cu ft box offers dual-side opening access, unlike the Maxsa Innovations single-hatch design. It provides 14 cubic feet of space, which is less than the Maxsa’s 17 cubic feet. However, it shares the same 165 lb load capacity. It is significantly lighter at 25 pounds compared to the Maxsa’s 35.3 pounds, which may help with fuel efficiency. It is also longer at 63 inches. Select this if you value lightweight construction and side access over the largest possible volume.
OMAC 8 cu ft Hard Shell Cargo Box
The OMAC 8 cu ft box is much smaller than the Maxsa Innovations model, offering only 8 cubic feet of storage. It features dual-side opening access for easy loading. It lacks a stated load capacity in the data, while the Maxsa supports 165 lbs. The OMAC is shorter at 49 inches and narrower at 28 inches, making it suitable for smaller vehicles or light cargo. Choose this compact option if you need easy access and a low-profile box for minimal gear.

Do any boxes allow access from both sides?
Yes, several models feature dual-side opening for easier loading. The GarveeTech 12 cu ft, Goplus 14 cu ft, and OMAC 8 cu ft boxes all open from both sides. This design is useful when parked in tight spots where rear access is blocked. The Maxsa Innovations model uses a single rear hatch instead.
Which option is the lightest to carry?
The Goplus 14 cu ft Dual-Side Opening Roof Box is the lightest at 25 pounds. This makes it easier to lift onto your roof racks alone. The OMAC 8 cu ft model is also relatively light, though its exact weight is not listed. Heavier options like the GarveeTech box weigh 39 pounds.
What is the maximum weight these carriers hold?
Most boxes on this list support a 165 lb load capacity. This includes the Maxsa Innovations 17 cu ft, GarveeTech 12 cu ft, and Goplus 14 cu ft models. The JEGS 18 cu ft carrier has a lower limit of 110 lb. Always check the specific weight limit before loading heavy items.

Are all these carriers hard shell designs?
Yes, every product listed uses a hard shell construction. This includes models from Maxsa Innovations, GarveeTech, JEGS, PM Performotor, Goplus, and OMAC.
