At Upfit Supply, we understand how critical it is to protect your vehicle’s interior—especially if you rely on your van for work. That’s why we’re diving into a product that delivers both durability and comfort: Legend DuraTherm Wall Liners for RAM ProMaster City. In this Unboxing Legend DuraTherm Wall Liners for RAM ProMaster City blog, we’re giving you a first look at what comes in the box, what makes these wall liners a smart investment, and what to know before installation.

Whether you’re new to outfitting your van or looking to upgrade an existing setup, these wall liners provide an exceptional combination of protection and insulation.

What’s Inside the Box?

Right away, you’ll notice the size of the box. It’s large, heavy-duty, and ships on a pallet, which is important to factor into your shipping expectations. This is because you’re receiving full-length wall panels designed to cover a significant portion of your van’s interior walls.

Inside the box, you’ll find:

  • Two large DuraTherm wall panels (passenger and driver sides)
  • A hardware kit that includes:
    • Self-threading screws
    • Matching gray screw cap covers for a clean finish

The wall panels are packed flat and protected to minimize any warping or damage during transit.

Key Features of the Legend DuraTherm Wall Liners for RAM ProMaster City

These aren’t your average plastic panels. The Legend DuraTherm Wall Liners for RAM ProMaster City are engineered for performance and longevity. Here’s what sets them apart:

1. Thermal and Acoustic Insulation

Each wall liner features:

  • A durable outer plastic shell
  • A layer of foil-backed insulation
  • A dense black insulation foam backing

Combined, this layered design reduces noise and helps regulate temperatures in the cargo area. Whether you’re trying to keep tools cool in the summer or maintain warmth in the winter, this insulation makes a noticeable difference.

2. Durable Wall Protection

Work vans take a beating. From lumber and tools to cargo and equipment, it’s easy to scuff or dent your van’s sheet metal. These high-impact panels act as a shield, helping to:

  • Prevent dents, scratches, and paint damage
  • Minimize corrosion risk
  • Extend the life of your vehicle’s interior

If you’re constantly loading and unloading gear, this added protection is invaluable.

3. Vehicle-Specific Design

These wall liners are precision-cut to fit the RAM ProMaster City. You’ll notice:

  • Cutouts for lights and contours
  • Pre-drilled holes for secure installation
  • A factory-finished look once installed

No trimming or guesswork required.

Texture and Color Options

The set we’re unboxing is finished in textured gray, which is not only the most popular choice but also helps to:

  • Hide scuffs and dirt
  • Offer a slightly more rugged appearance
  • Provide a non-reflective surface

If you’re going for a brighter, cleaner look, these wall liners are also available in smooth white. Just note: the white version does not include the same textured finish.

Installation Notes & Considerations

Installing the Legend DuraTherm Wall Liners for RAM ProMaster City is straightforward, but there are a few things to keep in mind.

Hardware and Fitment

  • Each pre-drilled hole aligns with safe points in the van for self-threading screws.
  • After installation, gray screw caps snap over each fastener to create a polished, OEM-like appearance.
  • Use a powered screwdriver or light impact driver for easy install.

Glass and Compatibility

These liners are designed for solid-panel vans. If you have factory glass windows on the sides, you may not want—or be able—to install wall liners in those areas. In our case, we used a glass delete kit, which allows us to install panels over the window cutouts.

Part of a Larger System

It’s important to remember: these are just the wall liners. The full van liner system includes:

  • Ceiling liners
  • Door liners
  • Rubber or rigid flooring systems

Each is sold separately. This modular approach allows you to buy only what you need, but also means you’ll want to plan ahead if you’re going for a complete upfit.

If you order wall liners first and then add ceiling liners later, for example, you may end up paying for LTL freight shipping twice—which can get expensive. Consider bundling products when possible.
