What Size Crossbars Fit a Subaru Crosstrek?

If you’re a proud Subaru Crosstrek owner, you already know this compact SUV blends rugged capability with everyday practicality. Whether you’re heading up to the mountains for a weekend ski trip, loading up bikes for a family adventure, or strapping on a cargo box for extra storage, adding crossbars to your roof is one of the smartest upgrades you can make. But here’s the catch: not all crossbars are created equal—and choosing the wrong size can lead to instability, wind noise, or even damage to your vehicle.

So, what size crossbars fit a Subaru Crosstrek? The short answer is that most Crosstreks—from the 2013 model year onward—work best with crossbars between 46 and 50 inches in length. However, the “right” size depends on several factors, including your specific model year, whether you have factory-installed roof rails, and what kind of gear you plan to carry. In this guide, we’ll walk you through everything you need to know to pick the perfect crossbars for your Crosstrek, from OEM recommendations to top aftermarket brands, installation tips, and real-world usage advice.

We’ll also cover weight limits, aerodynamic design, noise reduction, and how to ensure your setup is safe and secure. Whether you’re a weekend warrior or a daily commuter who occasionally needs extra space, this guide will help you make an informed decision—so you can hit the road with confidence, knowing your gear is safely secured overhead.

Understanding Your Subaru Crosstrek’s Roof System

Before you start shopping for crossbars, it’s important to understand how your Crosstrek’s roof is designed. Unlike some vehicles that come with a bare roof, the Crosstrek typically includes factory-installed roof rails—those raised side bars that run front to back along the edges of the roof. These rails are your anchor points for crossbars, and they play a crucial role in determining which crossbars will fit properly.

Factory Roof Rails: Fixed vs. Raised

Most Subaru Crosstreks come equipped with fixed roof rails, meaning they’re permanently attached to the vehicle and cannot be removed. These rails are designed to support crossbars and distribute weight evenly across the roof structure. However, not all Crosstreks are identical. Some trims—especially base models—may have lower-profile rails, while higher trims (like the Limited or Wilderness) often feature raised rails that sit slightly higher off the roof. This difference affects how crossbars attach and whether certain aftermarket systems will fit without modification.

It’s also worth noting that the Crosstrek’s roof rails are not full-length. They typically span from just behind the front doors to near the rear hatch, leaving a gap in the middle. This means crossbars must be long enough to bridge that gap while still providing secure mounting points at both ends.

Roof Load Capacity: What You Need to Know

Every vehicle has a maximum roof load capacity, and the Subaru Crosstrek is no exception. This capacity is split into two categories: dynamic (while driving) and static (when parked). For most Crosstrek models, the dynamic weight limit is around 150 to 165 pounds, while the static limit can be higher—sometimes up to 600 pounds—when the vehicle is stationary. However, these numbers can vary slightly by model year and trim, so always check your owner’s manual for the exact specifications.

Why does this matter for crossbar selection? Because even if your crossbars are the right size, overloading them can damage your roof, compromise handling, or even cause a safety hazard. For example, a heavy rooftop cargo box filled with gear could easily exceed the dynamic limit if not properly distributed. That’s why it’s essential to choose crossbars with a weight rating that matches or exceeds your intended use—and to never exceed the vehicle’s total roof capacity.

Measuring Your Roof Rails

If you’re unsure whether your Crosstrek has the standard rail setup, you can easily measure it yourself. Use a tape measure to check the distance between the inner edges of the front and rear roof rails. On most Crosstreks, this measurement falls between 46 and 50 inches. This range is a key indicator of the ideal crossbar length.

For example, if your measurement is 48 inches, you’ll want crossbars that are at least 48 inches long—but not so long that they overhang excessively. A little overhang (1–2 inches on each side) is acceptable and can actually help with accessory mounting, but too much can create wind noise, increase drag, and look unbalanced.

OEM Subaru Crossbars: The Factory Option

If you’re looking for a seamless, no-fuss solution, Subaru’s own OEM (Original Equipment Manufacturer) crossbars are a great place to start. Designed specifically for the Crosstrek, these crossbars are engineered to fit perfectly, match the vehicle’s aesthetics, and meet Subaru’s safety and performance standards.

Specs and Compatibility

Subaru offers crossbars as a factory accessory, and they’re available through dealerships or online parts retailers. For most Crosstrek models (2013–present), the OEM crossbars are approximately 48 inches in length, making them ideal for the standard roof rail spacing. They feature a sleek, low-profile design that minimizes wind noise and blends well with the vehicle’s styling.

One of the biggest advantages of OEM crossbars is their ease of installation. They typically attach using pre-existing mounting points on the roof rails, requiring no drilling or modification. Most models use a tool-free clamp system that allows you to install or remove the crossbars in under five minutes—perfect for drivers who only need them occasionally.

Pros and Cons of OEM Crossbars

Let’s break down the benefits and drawbacks:

Pros:
– Perfect fit for your Crosstrek model
– Matches factory design and color
– Easy, tool-free installation
– Backed by Subaru warranty
– Optimized for aerodynamics and noise reduction

Cons:
– Higher price point compared to aftermarket options
– Limited accessory compatibility (some third-party racks may not fit)
– Fewer customization options (e.g., color, finish)

Despite the higher cost, many Crosstrek owners prefer OEM crossbars for their reliability and peace of mind. If you plan to use your roof rack system frequently and want a hassle-free experience, Subaru’s factory crossbars are a solid investment.

Where to Buy OEM Crossbars

You can purchase genuine Subaru crossbars directly from your local dealership or through authorized online parts retailers like SubaruPartsDeal.com or OEMSubaruParts.com. Be sure to have your vehicle’s VIN handy to ensure compatibility, as crossbar designs can vary slightly between model years.

Aftermarket Crossbar Options: Thule, Yakima, and More

While OEM crossbars are a great choice, many Crosstrek owners turn to aftermarket brands for greater flexibility, lower prices, or enhanced features. Companies like Thule, Yakima, and Rhino-Rack dominate the rooftop cargo market, offering a wide range of crossbars designed to fit the Subaru Crosstrek.

Thule Crossbars for the Crosstrek

Thule is one of the most trusted names in roof rack systems, and their products are known for durability, sleek design, and excellent aerodynamics. For the Subaru Crosstrek, Thule offers several compatible crossbar kits, including the popular Thule WingBar Evo and Thule SquareBar Evo.

The Thule WingBar Evo is a top pick for many drivers. These crossbars are 47 inches long, making them a near-perfect match for the Crosstrek’s roof rail spacing. They feature a unique wing-shaped profile that reduces wind noise and drag, improving fuel efficiency and driving comfort. The integrated rubberized coating protects your roof rails from scratches, and the tool-free installation makes setup a breeze.

Thule also offers complete roof rack systems, such as the Thule Rapid Traverse Foot Pack, which includes both feet and crossbars. These systems are designed to work seamlessly with the Crosstrek’s factory rails and provide a secure, vibration-free fit.

Yakima Crossbars: A Close Competitor

2>Yakima is another leading brand in the roof rack industry, and their products are highly regarded for their versatility and build quality. For the Subaru Crosstrek, Yakima offers the JetStream Crossbars, which come in 47-inch and 50-inch lengths—both suitable for most models.

The JetStream bars feature a rounded, aerodynamic design that minimizes wind noise and turbulence. They’re made from lightweight aluminum, making them easy to handle during installation, yet strong enough to support heavy loads.

Comparing OEM vs. Aftermarket

So, should you go with OEM or aftermarket? Here’s a quick comparison:

– Fit: OEM crossbars are guaranteed to fit; aftermarket options may require verification.
– Price: Aftermarket is usually more affordable.
– Features: Aftermarket brands often offer more advanced aerodynamics and accessory compatibility.
– Warranty: OEM comes with Subaru’s warranty; aftermarket brands have their own coverage.

Ultimately, the best choice depends on your budget, needs, and preferences. If you value convenience and factory integration, go OEM. If you want more options and better value, aftermarket is the way to go.

How to Choose the Right Crossbar Size

Now that you know your options, let’s talk about how to choose the right crossbar size for your Subaru Crosstrek. It’s not just about picking the longest bar available—size matters for safety, performance, and aesthetics.

Measuring for the Perfect Fit

Start by measuring the distance between the inner edges of your front and rear roof rails. Use a tape measure and record the length in inches. Most Crosstreks fall between 46 and 50 inches, but it’s always best to measure your specific vehicle.

Next, consider the overhang. Crossbars should extend slightly beyond the rails—about 1 to 2 inches on each side—to provide secure mounting points for accessories. However, too much overhang can create wind noise, increase drag, and look unbalanced. Aim for a total length that’s 2 to 4 inches longer than your rail spacing.

For example:
– If your rail spacing is 48 inches, choose crossbars that are 50–52 inches long.
– If your spacing is 46 inches, 48–50 inch bars should work well.

Weight Rating and Load Distribution

Always check the weight rating of your crossbars. Most aftermarket bars support 165–220 pounds dynamically, which is well within the Crosstrek’s roof limit. However, the total load includes both the crossbars and your cargo, so don’t forget to factor in the weight of bike racks, cargo boxes, or other accessories.

Distribute weight evenly across both crossbars. Avoid placing heavy items directly over one bar, as this can create stress points and affect handling. If you’re carrying long items like kayaks or ladders, use padding and secure them with high-quality straps.

Aerodynamics and Noise Reduction

Wind noise is a common complaint with roof racks, but the right crossbars can make a big difference. Aerodynamic bars—like Thule’s WingBar or Yakima’s JetStream—are designed to cut through the air smoothly, reducing turbulence and noise.

Look for crossbars with integrated fairings or rubberized coatings. These features not only improve aerodynamics but also protect your roof rails from scratches and wear.

Ease of Installation

Some crossbars are easier to install than others. Tool-free systems are ideal for drivers who want to remove the bars when not in use. Others may require a hex key or wrench, but offer a more secure fit.

Consider how often you’ll be using your roof rack. If you only need it a few times a year, a quick-install system might be best. If you’re a frequent traveler, a more permanent setup could save time.

Installation Tips and Best Practices

Once you’ve chosen the right crossbars, proper installation is key to safety and performance. Here are some tips to get it right the first time.

Step-by-Step Installation Guide

1. Clean the roof rails: Wipe down the rails with a damp cloth to remove dirt and debris.
2. Position the crossbars: Place them on the rails, ensuring even spacing and alignment.
3. Attach the feet or clamps: Follow the manufacturer’s instructions to secure the bars. Tighten evenly to avoid warping.
4. Check for movement: Gently rock the bars to ensure they’re firmly attached.
5. Test with light load: Before loading heavy gear, test the setup with a light item like a soft cargo bag.

Maintenance and Care

To keep your crossbars in top condition:
– Inspect them regularly for loose bolts or wear.
– Clean them with mild soap and water.
– Store them indoors when not in use to prevent corrosion.

Conclusion

Choosing the right size crossbars for your Subaru Crosstrek doesn’t have to be complicated. With most models requiring 46–50 inch bars, the key is matching length, weight capacity, and compatibility to your specific needs. Whether you go with OEM Subaru crossbars or a trusted aftermarket brand like Thule or Yakima, a well-chosen roof rack system will enhance your Crosstrek’s versatility and keep your adventures rolling.
