When it comes to maximizing both durability and safety in your cargo van, few upgrades are as simple yet impactful as a quality threshold upgrade. Today at Upfit Supply, we’re walking through the unboxing of Steel Door Sills for GMC Savana & Chevrolet Express Vans—a rugged solution from Legend Fleet that enhances grip, protects your flooring, and improves visual safety around your van’s entry points.

We recently got our hands on the safety yellow version of this steel sill kit, and in this post, we’ll walk you through what’s included, how the sills function, and why this upgrade belongs on your upfit list.

What’s in the Box: Unboxing Steel Door Sills for GMC Savana & Chevrolet Express Vans

As we unboxed the Steel Door Sills for GMC Savana & Chevrolet Express Vans, the first thing we noticed was their solid construction and bold color finish.

Inside the box, you’ll find:

  • One side door threshold sill
  • One rear door threshold sill
  • Self-threading screws for installation
  • Pre-drilled countersunk holes on each sill
  • A textured, non-slip surface designed for safety

There’s no extra packaging fluff here—just the durable steel parts you need to protect your van’s high-traffic thresholds.

Safety First: Why Yellow?

These steel sills come in a few finishes, but we opted for high-visibility yellow. Here’s why:

  • Enhanced visibility at entry points helps prevent missteps.
  • Ideal for worksites, especially in low-light conditions.
  • Pairs well with other yellow Legend accessories, like rear grab handles.

Although you can choose black or aluminum diamond plate variants, we find the yellow option particularly useful for identifying step zones clearly.

Built to Last: Construction and Design

The Legend steel door sills are engineered for long-term use. These aren’t thin overlays—they’re made from heavy-gauge steel with a protective finish that resists corrosion and wear.

Key features include:

  • Textured grip surface to reduce slipping
  • Powder-coated finish for durability
  • Countersunk holes for flush screw installation
  • Exact fit for GM van platforms

The side door sill is shaped to rest cleanly over your van’s side door opening, while the rear sill features a subtle lip that lines up neatly with the cargo area floor and factory threshold.

Easy Install with Self-Threading Hardware

Installation is straightforward. The kit includes self-threading screws to attach the sills directly to your van’s floor or existing threshold. No need for brackets or custom fittings.

What you’ll need:

  • Cordless drill
  • Phillips bit
  • Measuring tape or straight edge (optional)

Thanks to the pre-drilled holes, each sill is easy to line up. Simply position, drill, and fasten. Once installed, they feel completely solid underfoot.

If you’re working with a Legend Stabiligrip or Evolve rigid floor, these steel sills integrate perfectly. They’re designed to sit over the factory sill and flooring, creating a seamless transition that looks sharp and performs even better.

Where They Fit: Designed for GM Cargo Vans

These steel door sills are a vehicle-specific solution, custom-sized for both the Chevy Express and GMC Savana cargo van platforms. Whether you’re driving a short or extended wheelbase model, the sills are cut to fit precisely at both:

  • Side cargo door
  • Rear cargo door opening

They’re an excellent choice if your van sees a lot of daily traffic or equipment loading. By protecting the exposed floor edge, they reduce wear and tear, especially at high-impact zones where boots, dollies, and cargo often collide with the threshold.

Matching Your Van’s Full Upfit

At Upfit Supply, we don’t just recommend isolated products—we help you build a complete van interior solution. These steel threshold covers are a perfect pairing for:

  • Stabiligrip van floors
  • DuraTherm wall and ceiling liners
  • Rear grab handles
  • Diamond plate corner protectors

This modular approach means you can build your upfit in stages or buy everything at once using our Legend Liner Package, which bundles flooring and liners by vehicle type.

Why Upgrade Your Door Thresholds?

You may be wondering why upgrading your van’s door sills is even necessary. After all, GM includes a basic threshold in the cargo area.

However, the factory threshold isn’t designed for commercial use. Over time, foot traffic, sliding cargo, and moisture can cause scratches, dents, or even corrosion.

By installing these Steel Door Sills for GMC Savana & Chevrolet Express Vans, you’re investing in:

  • Better grip for safer entry and exit
  • Floor protection to extend the life of your investment
  • A professional look that adds value to your vehicle
  • Quick visual guidance in safety zones

If your crew is in and out of the van all day, this simple upgrade can reduce liability, extend van life, and even boost morale.

After unboxing and reviewing the Steel Door Sills for GMC Savana & Chevrolet Express Vans, we’re confident in saying this is a smart upgrade for any commercial GM van owner.

With tough steel construction, easy installation, and practical safety features, these sills punch far above their weight. They’re proof that small upgrades can deliver big results.
