What is the weight capacity of the roof rack on a Subaru?
The weight capacity of a Subaru’s roof rack is not a single universal number. It depends on your specific model, year, and whether you’re using factory roof rails or aftermarket crossbars. In general, you’ll encounter two ratings: a dynamic load rating (for loads while driving) and a static load rating (the roof’s structural limit when parked). Always verify the exact specification for your vehicle from official sources or your owner's manual.
Understanding these figures is essential for safe loading. The dynamic rating represents what you can carry while the car is in motion, considering wind, vibration, and road conditions, while the static rating indicates how much weight the roof structure can bear when the vehicle is stationary. Different Subaru models and roof configurations can yield different limits, and adding aftermarket racks can change the total allowable load. Therefore, treat the exact numbers as model-specific and consult official documentation for your exact configuration.
Where the capacity comes from and how to read it
Most manufacturers publish two roof-load figures: a dynamic rating and a static rating. The dynamic rating limits how much weight your roof-mounted gear can safely carry while you are driving, while the static rating covers the roof’s ability to bear weight when the vehicle is stationary. For Subarus, these numbers vary by model, year, and whether you’re using factory rails or aftermarket crossbars and mounts. Accessory and crossbar configurations can also affect the total allowable load.
Two key ratings you should look for
To determine the exact capacity for your vehicle, locate the official ratings published for your specific model and roof system. If the information isn’t readily visible in the manual, check the door jamb placard, the roof rail label, or Subaru’s official product pages for your year and trim. The figure you need is the combination of the roof system (rails and crossbars) plus any cargo loaded on top.
Here is how you can determine the exact capacity for your vehicle and accessories:
- Consult the owner's manual for your specific model/year to locate the roof load rating (dynamic and static).
- Inspect the placard or sticker on the driver's door jamb or under the roof rails that states the maximum load.
- Review Subaru's official site or your vehicle's accessories catalog for the exact capacity with factory rails, crossbars, and mounts.
- When using aftermarket crossbars, ensure the combined weight of rails plus cargo does not exceed the specified dynamic load of your system.
- Account for the weight of the rack itself (including any accessories) in your calculations and distribute weight evenly across the crossbars.
By verifying these sources, you can ensure you are not exceeding your Subaru's roof-carrying limit and maintain safe handling while driving.
Practical loading guidelines
To maximize safety and prevent roof damage, follow these loading practices. The numbers above are limits; practical safe loads depend on weather, speed, and driving conditions. Always err on the side of caution and regularly inspect your roof-load setup during trips.
Key guidelines for safe loading include:
- Distribute weight evenly across crossbars to avoid wind-induced sway.
- Place the heaviest items as low and as close to the rack as possible.
- Secure cargo with straps or racks rated for outdoor use; check tightening after a drive.
- Avoid stacking cargo higher than the roof line and keep the center of gravity low.
- Remove all loose items, ensure ladders or long loads are properly flagged, and stay mindful of height restrictions.
Adhering to these guidelines reduces the risk of rollover, wind noise, and damage to the roof or cargo.
Model-specific notes
Because Subaru offers different roof rail systems across models (Outback, Forester, Crosstrek, Impreza, Ascent, Legacy, etc.), always verify the exact figure for your configuration. If you use the factory rails with Subaru crossbars, the rating typically applies to the complete roof system, including the rails, crossbars, and anchors; third-party racks may require separate limits. When in doubt, contact a Subaru dealer or consult the official owner resources for your exact year and trim.
Summary
There is no single roof rack weight capacity for all Subarus. The safe load depends on your model, year, and whether you’re using factory or aftermarket gear. Always check the dynamic and static load ratings in your owner's manual or on the vehicle’s placards, verify with official Subaru resources, and follow prudent loading and distribution practices to ensure safe driving performance.
What is the roof rack limit on a Subaru Forester?
The dynamic roof rack capacity for a standard Subaru Forester is 176 lbs (80 kg), which is the weight limit when the vehicle is in motion. However, this limit is for the vehicle's roof, not the rack itself, and does not include the weight of the crossbars or any other accessories. The capacity can differ for models like the Wilderness, which has a significantly higher capacity designed for heavier loads like rooftop tents.
Standard Subaru Forester
- Dynamic load capacity: 176 lbs (80 kg)
- Note: This is the weight you can carry while driving. It must be less than the total weight of any roof rack, accessories, and cargo.
- For example: If your crossbars and other accessories weigh 40 lbs, you can only carry 136 lbs of cargo (176 lbs - 40 lbs).
Subaru Forester Wilderness
- Dynamic load capacity: 150 lbs (68 kg)
- Note: The Wilderness model has a different capacity, and its crossbars are significantly beefier to support heavier loads like rooftop tents.
Other considerations
- Static load capacity: The static (stationary) load capacity is usually much higher than the dynamic load capacity, often three times more. However, you should always follow the manufacturer's dynamic load limit for safety reasons.
- Consult your owner's manual: Always refer to your specific model's owner's manual for the most accurate weight capacity information.
Is there a weight limit for roof racks?
The roof rack weight limit is determined by the vehicle's roof capacity, not just the rack itself. To find the correct limit, check your vehicle's owner's manual and subtract the weight of the rack to find the total weight for your cargo. For example, if your car has a 200 lb limit and the rack weighs 60 lbs, you can only add 140 lbs of cargo.
Key factors
- Vehicle's dynamic limit: This is the maximum weight the roof can handle while the car is moving. Most passenger vehicles have a dynamic limit between 75 and 150 pounds, though some SUVs can handle more.
- Rack weight: The weight of the roof rack itself must be factored into the total weight you carry.
- Static vs. dynamic load: The static (parked) load limit is much higher than the dynamic (moving) limit. This is why some people are able to use rooftop tents while the vehicle is stationary, but this weight must be removed before driving.
- Safety and handling: Exceeding the weight limit can affect your vehicle's handling, especially during braking and cornering. Manufacturers set conservative limits for safety reasons.
How to find your limit
- Consult your owner's manual: This is the most reliable source for your vehicle's maximum roof load capacity.
- Subtract the rack's weight: Once you have your vehicle's weight limit, subtract the weight of your roof rack system to determine how much cargo you can safely carry.
- Err on the side of caution: It's best to stay well below the limit to ensure safety, especially for items that are heavy or affect aerodynamics.
How much weight can the crossbars hold on a Subaru Outback?
150-pound
Factory Crossbars: Handy, But Limited
It's a smart and convenient setup for lighter gear. These work just fine for hauling a cargo box, a few duffel bags, or even your snowboard. With a 150-pound dynamic load rating (and up to 700 pounds static while parked), they're capable enough for simple tasks.
How much can a Subaru crosstrek roof hold?
At speed, the Crosstrek has a roof rail capacity of 176 pounds, meaning that the tent – when stowed and at speed – has to weigh less."
