When you’re building out a cargo van, one of the most important upgrades you can make is the floor. Today, we’re diving into the unboxing of the Stabiligrip Floor for GMC Savana & Chevy Express Vans—a premium rigid flooring solution designed by Legend for professional use. At Upfit Supply, we don’t manufacture this product, but we’ve reviewed and sold enough of these to know it stands out.

Whether you’re working out of a GMC Savana or Chevy Express, this floor was engineered with durability, stability, and performance in mind. Let’s walk through what comes in the box, what makes it special, and how it transforms your van interior into a rugged mobile workspace.

First Impressions: Big, Bold, and Built Tough

When the Stabiligrip floor for GMC Savana & Chevy Express vans arrives, the first thing you’ll notice is the sheer size of the packaging. It ships in a massive box—roughly 6 feet by 5 feet—and weighs in at 130 pounds. Because of this, it arrives via LTL freight on a pallet, so be prepared for a two-person lift.

We preemptively removed the contents from the box because of the weight. Once unpacked, you’ll find a three-piece rigid floor system, along with the installation components. The specific floor we’re reviewing here is for the 155-inch wheelbase version of the GMC/Chevy van lineup, but a 135-inch wheelbase model is also available—just make sure to select the correct version for your vehicle.

What’s Included in the Stabiligrip Floor Kit?

Here’s what you can expect to find inside the kit:

  • Three rigid floor panels (front, middle, rear)
  • Two aluminum joiner strips for seamless assembly
  • Glue/sealant for installation
  • Pre-cut mounting points for cargo D-rings
  • Precision-cut contours for wheel wells, doors, and filler necks

Each piece is clearly labeled and cut to match the unique contours of the GMC Savana or Chevy Express. That includes areas like the driver-side fuel fill, cargo tie-down rings, and step cutouts by the sliding door.

Why Choose the Stabiligrip Floor?

Legend makes several types of aftermarket flooring, but the Stabiligrip floor is the top-tier option in their lineup. Here’s why:

  • Rigid and flat: Unlike rubber floors that flex into your van’s ridges, Stabiligrip creates a flat, stable walking and loading surface.
  • Slip-resistant texture: Offers traction underfoot while still allowing materials like pallets to slide smoothly.
  • Composite material: Made from a durable plastic blend that won’t rot like wood. It resists water, chemicals, and extreme temperatures.
  • Precision fit: CNC-cut for a vehicle-specific installation, ensuring every curve and opening is accounted for.
  • No drilling needed: The floor sits flush inside the van and stays in place due to weight and precision fit.

This flooring is built to withstand years of use. Whether you’re loading heavy machinery, rolling carts, or storing shelving units, this floor can take it.

Assembly and Install: Designed for Simplicity

One of the things we love most about the Stabiligrip floor for GMC Savana & Chevy Express vans is how straightforward the installation process is.

  1. Bring each panel into the van individually—front, middle, and rear.
  2. Use the included aluminum joiner strips to connect each section. These sit flush with the floor and lock the panels together.
  3. Apply the provided sealant glue to both sides of the joiners before pressing panels into place.
  4. No screws or mechanical fasteners needed—the floor is heavy enough to stay put.

Because it’s a floating floor system, there’s no drilling into your van’s metal base. That also makes it easy to remove or replace if needed. If you’re installing shelving afterward, you can still drill through this floor to set your plus nuts or anchors.

Floor Sil Options: Don’t Skip This Step

To protect your new floor and add a polished finish, we highly recommend adding door thresholds (also called sill plates). These mount over the edges of the floor at the side and rear doors.

You can choose from:

  • Aluminum sills (included with some kits)
  • Black powder-coated steel sills
  • High-visibility yellow sills (our favorite for a sharp, professional look)

We paired our Stabiligrip floor with the yellow steel sills, and they look fantastic while offering extra protection where your van gets the most wear.

Compatible with Your Van’s Features

The rear panel includes cutouts for the wheel wells and cargo tie-downs, ensuring you don’t lose access to existing features. Everything is pre-aligned, so you don’t need to trim or adjust anything.

Notably, if you’ve got dual sliding doors or a custom van configuration, we recommend checking for a compatible model. Each floor is wheelbase-specific and van-specific, so be sure you’re choosing the correct one for your setup.

Built for Daily Demands

If your van is your office, then the floor is your foundation. The Stabiligrip rigid floor offers:

  • A stable, flat platform that’s easier to walk, roll, and work on
  • Moisture resistance for unpredictable jobsite conditions
  • Impact resistance for heavy-duty use
  • A seamless surface with easy-to-clean properties

It’s ideal for fleet upfits, delivery drivers, contractors, or any tradesperson who wants a professional-grade upgrade.
