One of the most important pieces of adventure vehicle prep is on board air. Lowering air pressures is one of the most important tricks any Overlander has up their sleeve to improve traction, stability, and ride comfort off pavement...but without a way to put air back in, you're in a canoe without a paddle. Further, we couldn't imagine venturing off the beaten path without a way to put air back in your tire in case of a boo boo. 

Our Airline kit pairs with our existing VS30 Sprinter Air Compressor mounting bracket and the industry benchmark 'ARB Twin' compressor to create a cleanly packaged, easy to use, high output system. This kit uses lightweight and flexible DOT rated air lines made to handle the abuse of long haul trucking, and high quality push-to-connect fittings with integrated mounting holes. Our kit includes 3 quick release air chucks with aluminum mounting brackets: 1 front (accessible with the hood closed!) and 2 rear ports. We include a 25 foot coiled hose with locking air chuck to ensure easy and quick setup, fill up, and pack down. 

Portable compressor kits take up valuable storage space and can be cumbersome to setup. Our competitors kits involve popping the hood, or using multiple hoses at once. We've been doing this for decades, 1 hose is all you need, and allows you to be more precise filling each tire, with minimal gear to fumble with.

The proven capability and massive CFM output of the ARB Twin air compressor is perfect for airing up high volume off road tires back to highway/loaded pressures. Our complete on board air system gives you the convenience to use it to its full potential.

How do I decide which system to buy? I'm a newbie.

  • We've prepared some comparison guides for our most popular systems, they can be found under the stage guides tab on the product page.

Which tune should I select?

  • We've prepared some valving charts based on van weights, they are at the bottom of each shock, and stage system page. You can select the tune from the options when adding your system to the cart.

I don't know what my van weighs. How do I find out?

  • Easy, most county landfills have a commercial scale. You can use the CAT SCALE LOCATOR to find the closest CAT certified scale. These are great, as they give us a front and rear axle weight separately.

Do I need adjustable shocks?

  • Our adjustable shocks are very popular, and offer a huge range of adaptability to your van. They are well suited to vans that see a wide range of payload and terrain. Do you like to exact every last bit of performance and comfort out of every situation? Or, do you prefer to live in the moment and keep your vehicle simple?

Can I upgrade my kit in stages?

  • Typically, yes. Our kits are designed to be modular, so that customers can add components in stages without having to buy many components twice. If you buy a stock stage, then lift the van later, your shocks will still work.

Do I have to lift my van to use your upgrades?

  • NO! All of our shock upgrades work as stock replacements. They are designed to work with both stock height and Van Compass lifted vans.

Is a lifted van safe to drive?

  • YES! Our lifted 2wd vans are roughly comparable to a stock 4wd van. We design our lifts to preserve factory suspension geometry and travel, as well as work with our upgraded shocks. Lifts will also allow fitment of larger tires, which help smooth out terrain and road irregularities. The combined effect is a van that is actually much better driving than their stock, delivery van roots suggest.

What size tire fits my _____?

  • We've prepared detailed fitment charts for each application, you'll find them in a tab on the product pages. We also recommend you consult your installer, and local tire shop. They are the experts when it comes to proven formulas with builds, and good tire choices for your area and use cases.

Does installation void my warranty?

  • Ultimately, the decisions for warranty lie with the Dealer and Manufacturer, so you will want to contact them for an answer. Van Compass parts are designed with OEM performance in mind, and as thoroughly as possible. Many of our parts are stock replacements.

Do Van Compass products have a warranty?

Do you do installations?

  • We no longer do installations, we are focused 100% on designing, manufacturing and shipping the best possible products we can make.

How much does installation cost?

How long do your products take to install?

  • Installation instructions are found under the 'Instructions' tab on the product page. We list recommended labor hours for both home, and professional environments.

Can I install your products myself?

  • YES! Many of our customers are do-it-yourselfers, so our products are designed with the installer in mind. They have been thoroughly engineered to be durable, fit great, and easy for a human to install. We've prepared detailed instructions and fitment info to help you, so make sure you read them thoroughly. We've done our best to outline the tools, safety equipment, and various other tricks you'll need to be able to confidently install our products.

Will I need an alignment after installation?

  • We always recommend a quality, digital alignment be performed after any suspension modification where the struts are removed and reinstalled. Although many vans have limited adjustment, the TOE setting is critical to front end alignments, good tire wear, and safe drivability and should always be properly checked after installation.

When will my order ship?

  • We allocate and ship orders on a first in, first out basis. We understand, it's frustrating waiting for long periods of time and how that impacts the unique circumstances of our customers. For more information on our shipping and order policies, please read here: Shipping, Return and Cancellation Policies

Do I need to put a deposit down?

  • Many credit card companies provide only a small window to collect funds from online orders. With the long and often un-predictable lead times many of our products are experiencing, this small windw is not a good fit. The unique nature of our business and customer base dictate that we take a full deposit up front. If your order will be shipping freight, we will contact you at the time of shipment to ensure an accurate and fair rate. The 3% cancellation fee only covers the service charges we incur from the credit card companies.

Still have questions?

  • We'd love to chat!

Please fill out our contact form and someone will reach out to you as soon as they are able to!

Why can't I find your phone number?

  • With the unique nature of many of our customer's builds, the conversation is often drawn out over several months. Keeping a paper trail allows us to remember the specific names, vans, builds and needs for each of our customers. We're available to chat via appointment on a limited basis, so please email us first.
