Are Subaru roof racks interchangeable?

In short, not universally. Roof rack components and crossbars are generally not interchangeable across different Subaru models or generations because of variations in roof rail profiles, mounting feet, and weight ratings.

Subaru uses a variety of roof rail configurations across its lineup, including raised rails, flush/low-profile rails, and sometimes bare roofs that require clamps or adapters. Because mounting hardware and crossbar dimensions are tailored to specific rail shapes and model-year specifications, a rack that fits one Subaru may not fit another without adapters or a different feet kit. This article explains the factors that influence interchangeability and how to verify fit before purchasing or swapping racks.

Understanding Subaru roof rail configurations

Subaru’s roof rack ecosystem is built around a few core rail types, which determine compatibility with crossbars and feet:

• Factory raised rails common on many SUVs and wagons that require specific foot packs designed to clamp to that rail profile.


• Factory flush or low-profile rails (aero rails) with a different crossbar mounting footprint and often a separate feet design.


• Naked or glass roofs that rely on aftermarket clamp-on feet or track-based systems, which can require different hardware than rail-equipped models.


• Aftermarket crossbars or “universal” feet that claim broad compatibility but still depend on matching rail type and clamp design.

Because rail shapes and mounting footprints vary by model year and trim, never assume crossbars are interchangeable across Subaru models without checking the exact fit instructions from the rack manufacturer or Subaru’s official parts guidance.

Can racks be swapped between Subaru models or generations?

Swapping racks between Subarus hinges on whether the two vehicles share the same roof rail type and foot design. The most common incompatibilities come from mismatches in rail profile (raised vs flush), crossbar width and bar-spread requirements, and differing load ratings.

1. Identify your roof rail type: raised rails, flush rails, or a bare roof with mounting clamps.


2. Check the specific model year and trim to see which foot pack and crossbar system Subaru specifies for that vehicle.


3. Compare crossbar width, bar-spread, and overall length to ensure proper clearance and functionality on both vehicles.


4. Verify the rack’s load rating and aerodynamic compatibility, especially for highway use and wind noise considerations.


5. Consult fit guides from the rack manufacturer or a Subaru dealership to confirm exact compatibility for both vehicles.

If both vehicles share the same rail type and the feet and crossbars align with the same mounting geometry, interchange is more plausible. In most cases, however, you’ll need model-specific or year-specific hardware, or you may opt for aftermarket systems with clearly documented multi-vehicle compatibility and the correct adapters.

Practical considerations and alternatives

To avoid misfits and safety risks when dealing with Subaru racks, keep these practical points in mind:

• OEM Subaru racks are designed to integrate with specific roof rail designs and years; using the wrong year or rail type can compromise stability.


• Aftermarket brands (Thule, Yakima, Rhino-Rack, etc.) publish Fit Guides listing compatible Subaru models by year and rail type; always verify before purchasing.


• Even within the same model, generational changes can alter clamp geometry and bar width requirements, affecting compatibility.


• Never exceed the vehicle’s stated roof load limit, and secure cargo according to the rack’s instructions.

If you frequently interchange racks among multiple Subarus, consider a modular aftermarket system with adjustable feet that explicitly lists compatibility across a broad range of Subaru models, and maintain the exact fit kits needed for each vehicle. When in doubt, consult the manufacturer or a professional installer for confirmation.

Summary

Subaru roof racks are not universally interchangeable. Compatibility depends on the roof rail type (raised, flush, or bare), the model year, and the specific mounting feet and crossbar system. Always consult official fit guides from Subaru and from aftermarket brands, verify load ratings and clearance, and use the correct hardware for each vehicle to ensure safety and performance.

What Subaru parts are interchangeable?

Subaru parts interchangeability varies greatly by model and year, but generally, older models have more cross-model parts. For example, many parts from the 2002-2005 WRX are interchangeable with each other, and parts like suspension, brakes, and certain interior components are often compatible across related models within specific year ranges. Specific part compatibility, such as from the 1995-1999 Legacy, depends heavily on the exact component.
 
General rules for interchangeability

• Similar platforms: Parts are more likely to be interchangeable between models built on the same platform during the same time period. 
• Brake and suspension components: These often have a high degree of interchangeability within a specific year range, but always confirm details as some parts may require swapping multiple related components. 
• Engine swaps: Engine swaps are possible, but often require a compatible transmission and potentially wiring harness changes. 
• Body and interior parts: These can vary by year, trim, and body style (e.g., sedan vs. wagon). 

Examples of interchangeable parts

• 02-05 WRX: Front and rear subframes, hubs, axles, and the 5-speed transmission are largely interchangeable. 
• 06-07 WRX: Many parts are interchangeable with the 02-05 models, except for the engine and wiring harness. 
• Legacy/Outback:
  • 2000-2004: Rear struts are interchangeable, though ride height and clearance may vary. 
  • 1995-1999: Front doors, trunk/deck lids, and tail lights are generally interchangeable, but there may be wiring or feature differences. 
  • Ascent/Outback (2015-2022): Many front-end components like strut mounts, bearings, and sway bar bushings are shared between the Outback and Ascent. 

How to find specific part compatibility

• Consult online forums: Forums dedicated to Subaru models often have detailed discussions on specific part swaps. 
• Check compatibility lists: Websites and forums that focus on specific model years often provide compatibility lists. 
• Use online parts catalogs: Some online OEM parts dealers have cross-reference tools that can help you find compatible parts for different models and years. 

Are all roof racks compatible with all cars?

Not every car roof rack or rail system is compatible with every vehicle, and different brands of systems may not be compatible with each other. There could be incompatibilities based on size, weight or method of attachment, for example.

Can you transfer roof racks from one car to another?

Traditional roof racks suit only one mount type, so buying another car means buying a whole new roof rack system. Prorack Smartfoot kits are interchangeable and fit both through and flush style bars, which means switching your roof racks to another vehicle may be as simple as getting another fitting kit..
