Van Flares Guide: What They Are, Why You Need Them, and How to Choose the Right Ones

When I first started converting my Sprinter van, one of the best upgrades I made was adding van flares—also known as bump outs, side flares, or window popouts. Before installing them, I used to sleep curled up tight. But with the Sprinter flares in place? Game changer! Now I can stretch out sideways and actually get a good night’s sleep!

Got a Mercedes Sprinter, Ford Transit, or Ram Promaster van? This guide is like a friendly chat, sharing all my best tips on van flares and capsules – how to put them in, what’s great (and not so great) about them.

Ok. Let’s start.

Why Get Van Flares?

My biggest problem with a normal van was trying to sleep. I’m not super tall, but trying to stretch out straight from front to back just ate up so much space. If I tried to sleep sideways, my feet would be squished against one wall and my head against the other. It was like sleeping in a coffin! Most vans, I learned, only give you about 68 to 71 inches of bed width inside without these “pop-outs.” That’s just too short for anyone over about 5’7″ to really stretch out comfortably.

That’s where flares came in. They’re basically these big bubbles that stick out from the sides of your van. They added about 10-12 inches of total width to my sleeping area! Suddenly, I could sleep sideways without my feet or head touching the walls. That meant my bed wasn’t taking up the whole middle of the van anymore. It felt like I gained a whole new room for my kitchen and living area. This extra space directly impacts how much I enjoy being in my van – it’s so much more comfortable now, especially for getting good rest.

What Kinds of Flares Are Out There?

When I started looking, I found out there are different kinds, mainly based on your van model. You have to get the right one for your van’s year and shape – it’s like buying custom shoes! Most are made for Mercedes Sprinters (like my 144 model), Ford Transits, or Ram Promasters. They generally fit both high-roof and long vans.

But then I learned about the two big players: Flare Space flares and Van Speed capsules. This was a big decision for me!

Flare Space Flares: These have a more rounded, tapered design. They look a bit more like they were molded onto the van.

Van Speed Capsules: These are more squared-off and keep a consistent shape. When I saw them, I immediately thought, “Wow, those look like they belong there!” They really complement the van’s original straight lines, making the outside look super clean and integrated, not just like an “add-on.”

Do You Need Windows?

You can get them solid (no windows) or with windows. I went with windows for extra light and airflow. Van Speed offers cool CR Lawrence sliding bunk windows which are great for ventilation and keeping bugs out.

Materials.

Most good flares are made of fiberglass, which is super strong and lasts a long time. You’ll see some cheaper ones made of plastic, but I heard those might not hold up as well.

Which Vans Can Use Flares?

Flares aren’t one-size-fits-all. They’re made to fit specific models:

• Flarespace Sprinter (144 and 170)
• Ford Transit flares
• Ram Promaster (limited options)
• High-roof and extended wheelbase vans

If you’re searching for “flares near me” to get them installed, make sure the shop has experience with your exact van model and year.

With or Without Windows?

You can buy Sprinter window flares or solid ones:

• Window flares: Great for light, views, and airflow. I chose a sliding window style and love it.
• Solid flares: Better insulation and stealth.

About installation

Can You Install Them Yourself?

Yes, you can—but it’s not exactly a beginner-friendly project. It definitely helps to have an extra set of hands (and some experience doesn’t hurt either).

Okay, this was the scariest part for me: you have to cut a big hole in your van! It’s just like installing a window, but on a bigger scale.

Hiring a Pro

If cutting metal scares you, pay $500–$1,000 for a pro. They’ll ensure no leaks and a perfect fit. I almost went this route, but DIYing was rewarding and saved cash.

Tools

Here’s a full list of tools that are good to have for installing van flares, like Flarespace Sprinter flares, Ford Transit flares, or any other DIY bump outs. You can probably get the job done without every single item, but having more of them makes the job easier and cleaner.

Cutting & Drilling

• Metal-cutting nibbler (best for clean cuts through sheet metal)
• OR Jigsaw with metal blades (a common alternative)
• Cordless drill & bits (for pilot holes, fasteners if needed)
• Hole saw (if you’re adding a window or vent)

Measuring & Layout

• Tape measure
• Straight edge or ruler
• Level (small one is fine)
• Masking tape (for marking cut lines and holding templates)
• Marker or paint pen

Safety Gear

• Work gloves
• Safety glasses
• Hearing protection
• Dust mask or respirator (cutting fiberglass or metal creates fine dust)

Adhesion & Sealing

• Automotive-grade adhesive/sealant (like 3M 5200 or Sikaflex)
• Primer/etching compound (to prevent rust around cut edges)
• Caulk gun (for applying sealant)
• Clamps or painter’s tape (to hold the flare in place while curing)
• Alcohol wipes or degreaser (for surface prep)

Finishing

• Sanding block or flap disc (smooth rough edges)
• Rags or shop towels
• Touch-up paint or primer (protect exposed metal edges)

Is it Hard?

For me, it looked pretty tough. My friend is really good at DIY stuff, so he helped. He said it was “moderately complex.” Basically, if you’re good with tools and comfortable cutting metal, you can do it yourself. But if you’re like me and prefer not to mess up your van, getting a pro to do it is a smart move. You really don’t want leaks!

Installation Advantage: This is where Van Speed capsules really shined. They have this cool flange design that wraps around the cut-out, so you can clamp them in place from inside the van while the glue dries. My friend said this made it much easier to get a super strong, consistent bond. For Flare Space, you often have to rely on tape from the outside, which can be trickier.

Time:

Even for experienced people, it can take 6-10 hours for both sides.

Instructions

Good brands will send you templates and videos to help, which is super helpful if you go the DIY route.

After they’re installed, you’ll want to insulate them inside. It makes a huge difference for keeping the van warm in winter and cool in summer. My flares weren’t pre-insulated, so that was an extra step.

Paint & Matching

Don’t forget: flares come in a primer or gel coat, so you’ll need to paint them. Matching your van’s color perfectly might require pulling a body panel so the shop can scan it with a spectrometer.

• Painting cost: $600–$1,200
• Install cost: $500–$1,000
• Total cost: $2,500–$4,500 depending on brand and install

What About the Cost? (My Wallet Felt This One!)

Flares aren’t cheap, but I really believe they’re worth it for the space.

• Just the Flares: When I was looking, Van Speed capsules were around $1,799, while Flare Space flares were about $2,500. So Van Speed was actually $700-$800 cheaper for a similar space gain!
• Painting: They usually come in plain white or gray, so you’ll need to paint them to match your van. That cost me another $600-$1,200. My paint shop even removed a small piece of my van (like the fuel flap) to get a perfect color match with their fancy spectrometer – just using the paint code isn’t always enough!
• Installation: If you get a pro to install them (which I recommend!), factor in another $500-$1,000.
• My Total: For my setup with Van Speed, painting, and installation, it came out to be about $3,000 to $4,000 all in.

Final Thoughts: Are Van Flares Worth It?

Absolutely!

Being able to sleep sideways makes van life so much more comfortable for me. It means I have more room for everything else, and my van feels much more like a tiny home.

Interior Finishing: A Small Detail, Big Difference

One thing I learned about later is how much easier the interior trim is with the squared-off Van Speed capsules. Their straighter lines mean less complicated upholstery work inside. Those curvy Flare Space ones often need special, more expensive trim rings to finish the inside neatly. My friend, who’s good with upholstery, said the Van Speed design made his job much simpler for the interior.
