What Size Crossbars for Subaru Crosstrek? A Complete Guide

If you’re a Subaru Crosstrek owner looking to haul gear—whether it’s a rooftop cargo box, bike rack, or kayak—you’ve probably asked: *What size crossbars do I need?* It’s a great question, and one that deserves a detailed answer. The right crossbars don’t just make loading easier; they ensure safety, reduce wind noise, and protect your vehicle’s roof from damage.

The Subaru Crosstrek, known for its rugged capability and compact design, comes equipped with roof rails from the factory. But those rails alone aren’t enough to carry heavy or bulky items. That’s where crossbars come in. They bridge the gap between the rails, creating a stable platform for your cargo. However, not all crossbars are created equal. Size, material, weight capacity, and compatibility all play a role in finding the perfect match for your Crosstrek.

In this guide, we’ll walk you through everything you need to know about choosing the right crossbar size for your Subaru Crosstrek. Whether you’re driving a 2013 model or a 2024, we’ll cover OEM specifications, aftermarket options, installation tips, and safety guidelines. By the end, you’ll have the confidence to pick crossbars that fit your lifestyle—and your vehicle—perfectly.

Understanding Your Subaru Crosstrek’s Roof System

Before diving into crossbar sizes, it’s important to understand how your Crosstrek’s roof system works. The Crosstrek features factory-installed roof rails that run along the length of the roof. These rails are not just decorative—they’re structural components designed to support crossbars and, ultimately, your cargo.

The roof rails are typically made of durable aluminum or steel and are mounted directly to the vehicle’s roof structure. They’re spaced approximately 31 to 33 inches apart, depending on the model year. This spacing is crucial because it determines the minimum and maximum length of crossbars you can safely install.

Most Crosstreks come with two roof rails—one on each side—and the crossbars span between them. The crossbars themselves are usually mounted using clamps or brackets that attach to the rails without drilling. This design allows for easy installation and removal, making it simple to switch between carrying gear and keeping the roof clean.

It’s also worth noting that the Crosstrek’s roof is not flat. It has a slight curvature, which means crossbars must be designed to conform to that shape. Flat or rigid crossbars that don’t match the roof’s contour can create gaps, leading to noise, vibration, and potential damage over time.

Roof Rail Spacing by Model Year

Roof rail spacing can vary slightly between Crosstrek generations. Here’s a quick breakdown:

– **2013–2015 Crosstrek (First Generation):** Roof rails are spaced about 31.5 inches apart.
– **2016–2020 Crosstrek (Second Generation):** Spacing increases slightly to around 32 inches.
– **2021–2024 Crosstrek (Third Generation):** Rails are spaced approximately 33 inches apart.

These measurements are critical when selecting aftermarket crossbars. If the crossbars are too short, they won’t reach both rails. If they’re too long, they may overhang or interfere with side mirrors or roof trim.

Always measure your own vehicle’s rail spacing before buying crossbars. Use a tape measure to check the distance between the inner edges of the front and rear roof rails. This ensures accuracy, especially if your Crosstrek has been modified or repaired.

Dynamic vs. Static Weight Limits

Another key factor in choosing crossbars is understanding your Crosstrek’s weight limits. Subaru specifies two types of weight capacities:

– **Dynamic Weight Limit:** 150 pounds (68 kg) – This is the maximum weight your roof can safely carry while the vehicle is in motion. It includes the weight of the crossbars, cargo, and any accessories.
– **Static Weight Limit:** 600 pounds (272 kg) – This is the maximum weight the roof can support when the vehicle is parked and stationary. It’s useful for loading heavy items like rooftop tents, but never exceed the dynamic limit while driving.

These limits are set by Subaru based on the strength of the roof structure, roof rails, and mounting points. Exceeding the dynamic limit can compromise vehicle handling, increase braking distance, and potentially cause roof damage or failure.

Even if your crossbars are rated for higher weights, you must always follow Subaru’s guidelines. For example, if you install crossbars rated for 200 lbs, you still can’t exceed the Crosstrek’s 150-lb dynamic limit.

OEM Subaru Crossbars: The Factory-Recommended Option

If you want the safest, most reliable option, Subaru’s OEM (Original Equipment Manufacturer) crossbars are the way to go. These crossbars are designed specifically for the Crosstrek and are engineered to meet Subaru’s strict safety and performance standards.

Dimensions and Specifications

Subaru OEM crossbars for the Crosstrek are typically **48 inches (122 cm) long**. This length is carefully calculated to span the roof rails with minimal overhang while providing a stable platform for cargo.

They are made from lightweight yet durable aluminum, which resists corrosion and reduces overall weight. The crossbars feature a low-profile, aerodynamic design that helps minimize wind noise and drag—especially important for fuel efficiency on long drives.

The crossbars attach to the roof rails using Subaru’s proprietary mounting system. This usually involves clamps that secure tightly to the rails without requiring tools for installation. Many owners report that OEM crossbars are quiet, even at highway speeds, thanks to their snug fit and vibration-dampening design.

Pros and Cons of OEM Crossbars

Let’s break down the advantages and disadvantages of choosing Subaru’s factory crossbars:

**Pros:**
– Perfect fit for your Crosstrek model year
– Quiet operation with minimal wind noise
– Full compatibility with Subaru roof accessories (e.g., cargo boxes, bike racks)
