Roof Racks or Crossbars For Subaru Ascent

If you find your Subaru Ascent has a pair of raised OEM roof rails, you can use the below crossbars as a foundation of a complete rooftop cargo management system. With a compatible roof rack system on the car roof, you can consider adding cargo boxes, cargo baskets, cargo bags, or other roof-mounted cargo carriers to carry what you need out there for most outdoor activities.

Option One

Rhino Rack Vortex crossbars 58-inch model

Rhino-Rack Vortex Aero Bar is the first consideration for Subaru Ascent with factory-installed raised roof rails. Vortex Aero bar has multiple length options for different car models, so you must pick the right size option to work with your Subaru Ascent. We have done the study and found the perfect suitable size is 54-inch Rhino-Rack Vortex crossbars, which can perfectly fit on the roof of Subaru Ascent. You need to get a set of compatible Rhino-Rack mounting feet to work with the Vortex crossbars.

Option Two

Malone SteelTop Crossbars

You can consider using a pair of 58-inch Malone SteelTop crossbars to hold most roof-mounted cargo carriers. However, most people wonder if they need a pair of crossbars for using roof-mounted cargo bags, and we have opinions on the topic.

Malone crossbars have integrated mounting feet on each bar, so you get a complete roof rack system with one purchase. However, the Rhino-Rack Vortex crossbars are combinations of two bars and four mounting feet, and bars and mounting towers are not in a bundle. You need to pay twice to get a complete roof rack system if you choose to use the Rhino-Rack Vortex crossbars.

Option Three

Malone AirFlow2 58-inch For Subaru Ascent

Malone AirFlow2 is another solution to create a roof rack system on your Subaru Ascent. When choosing the appropriate size of Malone AirFlow2, the 58-inch model is the perfect result. Malone crossbars are much cheaper than Rhino-Rack bars, so you can choose the one that fits your budget. 

If you prefer to buy genuine roof racks for your Subaru Ascent, you can contact the local Subaru dealer to consult for recommendations. Otherwise, you can find compatible roof racks on Amazon or Ebay for your Subaru models.

After having a pair of study crossbars on your Subaru Ascent, you can follow the recommendations below to find a roof-mounted cargo carrier to transport almost everything on the roads.

PerFlex Exclusive Rooftop Cargo Carrier

Although your Subaru Ascent has a large trunk, you can use a PerFlex cargo box to add extra storage space on the car roof. The Perflex provides 17.7 cubic feet of space for luggage. PerFlex cargo boxes have three color options: black, silver, and white, so you can pick a color that matches your Subaru Ascent. However, if you want to repaint a cargo box to another color, whatever the color is, you can follow a guide to learn and DIY the color changing for a hardshell cargo box.

What it looks like after having a Perflex cargo box on a car

Its dimensions are 73 x 34 x 17 inches or 185 x 86.36 x 43.18 cm (L x W x H), so you can use these numbers to know the actual size of a Perflex cargo box and check if you can put a specific item into the cargo box. Most hardshell cargo boxes are universal fit on roof racks or crossbars, but some particular models require minimum and maximum bar spreads between two crossbars; furthermore, the Perflex 17.7 cargo box needs a distance between front and back crossbars to be 22 – 36 inches or 56 – 91.5 cm.

If you have a pair of adjustable crossbars, as the above options, on the car roof, you don’t have to worry about the bar spread fitment.

PerFlex Cargo Carrier on Subaru Ascent

The Perflex 17.7 cargo carrier weighs 36 pounds, and we believe most of us can lift it for installation; however, we recommend two men for the job because of the security and accuracy concerns. We can find an integrated lock mechanism on the PerFlex cargo box to protect your belongings during outdoor trips. We know some tactics to increase the security of a hardshell cargo box.

The manufacturer gives you 4 keys, so you better leave a key in the car for times when you forget to bring a key with you. Subsequently, we know some methods to open a cargo box without keys for people who lost their keys to their cargo box, not only PerFlex.

JEGS cargo carrier 18 Cubic Feet

If you have a tight budget, the JEGS cargo carrier is an affordable option to create ample storage space on your Subaru Ascent. When checking on JEGS cargo carriers, you find two size options: 10 cubic feet and 18 cubic feet

We recommend the 18 cubic feet model for your Subaru Ascent. JEGS has the lowest price compared to other options in this article. However, it is a square cargo box not for carrying long gear because of its 57-inch length.

It is a perfect solution for loading road trip luggage and equipment. You can find more information about the JEGS cargo carrier in another post, which introduces its features, designs, dimensions, and loading capacity with videos, photos, and reviews.

The Thule Motion XT series has 4 size options and three color selections, so you can choose one that meets the size of your luggage or gear. We recommend the XXL model for your Subaru Ascent because of its 22 cubic feet of internal space.

You can find Black, Titan, and Grey color options to match different car styles. However, some people decide to repaint their cargo boxes with unique color styles to showcase their personalities. The Thule Motion XT is the most expensive in this article, but it is worth the investment because of its quality and trustworthiness.

Compare Thule Motion XT with Thule Force

If you want to know if the Thule Motion XT XXL is long or wide enough for your luggage or gear, you can use its dimensions 91.5 x 37.5 x 18 inches or 232.41 x 95.25 x 45.72 cm (L x W x H) to know its actual size and check the suitability.

However, you should pay attention to the extra height when adding a rooftop cargo carrier to your Subaru Ascent because the added height can cause driving difficulty when entering places like underground parking.
