Built for the Grenadier. Not Borrowed from a Shelf.
The INEOS Grenadier is purpose-built for genuine off-road work. Your liner should be too. The Trekker Premium Trunk Liner is molded to the exact floor geometry of the 2023+ Grenadier — every curve, every ridge, every rail — giving you a watertight, non-slip cargo surface that installs in seconds and cleans out in minutes.
Stop Cleaning Your Cargo Floor. Start Protecting It.
Most Grenadier owners don't realize how quickly a bare cargo floor takes damage. A wet cooler, muddy boots from a trail stop, gear shifting during a technical descent — the floor was never designed to take it raw. The Trekker Trunk Liner puts a purpose-built barrier between real-world use and your vehicle's floor, with deep sidewall channels that hold up to a full cooler worth of runoff before anything escapes.
The optional "With Cutouts" variant keeps access to your spare tire well and under-floor storage completely unobstructed — no awkward peeling, no lifting. If you use your Grenadier as a working vehicle, this is the variant to choose.

Two Variants. One Exact Fit.
Without Cutouts — full continuous liner surface for maximum coverage. Ideal if you keep cargo over the full floor and rarely need under-floor access.
With Cutouts — precision die-cut openings align exactly with the Grenadier's spare tire handle, jack storage, and floor latches. The liner stays in place permanently, and your utility tools remain accessible at all times.
Both variants use the same premium molded thermoplastic body with identical drainage channels, retention grommet, and carbon-fiber-style surface texture. The only difference is access — choose the one that matches how you use your Grenadier.

| Frequently Asked Questions |
| Does this fit the Grenadier Station Wagon and the Trialmaster? |
Yes. The Trekker trunk liner is precision-molded for all 2023+ INEOS Grenadier variants including the Station Wagon and Trialmaster. The cargo floor geometry is identical across both body styles. |
| Which variant should I choose — with or without cutouts? |
Choose "With Cutouts" if you need regular access to your spare tire, jack, or under-floor storage. Choose "Without Cutouts" for a cleaner look and full surface coverage if you don't need frequent floor access. |
| How does this compare to WeatherTech or a generic rubber mat? |
This liner is molded specifically for the Grenadier's cargo floor — not a universal fit. The precision edges, retention grommet, and raised sidewalls are all designed around the Grenadier's exact geometry. Generic mats slide, gap at the corners, and leave the sidewalls exposed. This one doesn't. |
| Can I run this liner with factory cargo rails installed? |
Yes. The liner is designed to work alongside the factory cargo rail system. The raised edges and drainage channels clear the rail anchor points on the standard Grenadier cargo floor. |
| Does it come with the floor liners as a bundle? |
The full floor + trunk liner set is available as a discounted bundle. See the links below to add complete cabin protection in one purchase. |
