INEOS Grenadier Rear Cargo Side Baskets: Standard vs. Inverter Fitment Guide

A practical fitment guide for the INEOS Grenadier Station Wagon. Learn how to inspect your rear left cargo wall in 30 seconds and select between Standard Fit and Inverter Fit modular side storage baskets.

Nov 08, 2026
THE 30-SECOND DECISION

Buy it if: You drive a 2023-2026 INEOS Grenadier Station Wagon (LHD or RHD), your trunk floor is packed, and you want rigid aluminum side storage mounted directly to factory threaded points without drilling.

Skip it if: You own a Quartermaster pickup (different bed geometry), or you have not checked whether your left cargo wall carries the factory 400W Power Pack inverter housing.

The INEOS Grenadier Station Wagon is engineered for demanding overland expeditions, but cargo floor space disappears quickly once fridge slides, storage drawers, and heavy toolboxes are loaded. Putting the upper cargo side walls to work recovers dead vertical space, keeping recovery straps, soft shackles, first aid packs, and trail gear secure, rattle-free, and accessible without digging through your trunk floor.

Installing modular side storage baskets converts bare window-line panels into dedicated gear stations. Because INEOS uses a standardized global body shell, this system fits Left-Hand Drive (LHD) and Right-Hand Drive (RHD) vehicles identically. Your only technical decision before checkout is verifying the equipment on your rear left cargo wall.

The First Gate: Understanding Left vs. Right Cargo Architecture

Unlike vehicle cockpits that flip controls between markets, the INEOS Grenadier rear cargo area features a uniform structural architecture worldwide. The rear passenger side in the UK and Australia shares the exact same left-wall geometry as the driver side in North America and Continental Europe:

01 / CABIN PRESSURE VENTS
Airflow Clearance

Both upper side walls integrate factory one-way cabin air extraction flaps. Basket mounting brackets are spaced to prevent vent restriction.

02 / FACTORY INVERTER LOCATION
Standardized Left Wall

The factory 400W Power Pack is installed exclusively on the lower left wall across all trims, protruding into the load bay.

03 / RIGHT-WALL UNIFORMITY
Universal Flat Profile

The right cargo wall is identical and flat on every Grenadier Station Wagon build, accepting a straight-bottom basket without variation.

The Expensive Mistake:

Never force a Standard Fit basket onto an inverter-equipped vehicle. The straight lower aluminum rail will collide directly with the plastic inverter shell. Forcing the bolts down will crack the factory power housing and cross-thread the body mounting inserts.

Standard Fit vs. Inverter Fit Comparison Matrix

To eliminate fitment interference, Strek Offroad manufactures the left-side basket in two dedicated geometry options:

Parameter / Dimension Standard Fit Inverter Fit
Steering Compatibility Universal (Both LHD & RHD) Universal (Both LHD & RHD)
Target Factory Trim Base & Fieldmaster (without Power Pack) Trialmaster & vehicles with optional 400W Power Pack
Left Basket Profile Straight, flat floor for maximum internal cargo volume Precision stepped relief cutout around inverter housing
Power Socket Access Not applicable (solid factory trim) Retains full clearance for 12V / 400W AC plug insertion
Right Basket Profile Universal flat-wall profile Universal flat-wall profile
Inverter Cover Clearance Zero clearance (will physically collide) Engineered 12 mm air gap around housing perimeter

The Hardware Boundary: What Is Included and What Is Not

Mechanical honesty matters when planning vehicle equipment. Review the physical scope of the kit before starting your project:

Component Category Included in Kit Buyer Responsibility
Storage Enclosures 1x Left basket + 1x Right basket (powder-coated aluminum) Third-party storage bags, foam liners, or cargo dividers
Mounting Hardware CNC bracket set, spacers, and vehicle-specific bolts Basic hand tools (hex key set, ratchet, socket)
MOLLE Grid System Standardized laser-cut slots on both side basket faces Quick-release clips, MOLLE pouches, tool mounts
Body Structural Fit Direct attachment to factory threaded body hardpoints Verifying body panel cleanliness and initial thread seating

30-Second Pre-Order Vehicle Inspection

Because these baskets fit LHD and RHD models without differentiation, confirming your required setup takes less than one minute:

1
Open Split Rear Cargo Doors

Access the rear cargo area to gain a clear line of sight along the interior window line.

2
Inspect Left Cargo Trim Lower Section

Look directly at the lower half of the left interior side panel, just above the floor line.

3
Identify Your Panel Contour

If the panel is smooth and flat, select Standard Fit. If a raised plastic housing with a 12V / 400W socket is present, select Inverter Fit.

Frequently Asked Questions

Q: Is this basket system compatible with Right-Hand Drive (RHD) vehicles?

This basket system installs identically on both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) Station Wagons. INEOS maintains an identical rear cargo shell layout across global markets, with the optional 400W Power Pack inverter housing consistently situated on the vehicle's left interior wall.

Q: Are the storage baskets sold individually or as a pair?

Each order ships as a complete matched pair containing one left-side basket, one right-side basket, and all vehicle-specific bracket hardware required for both sides of the cargo trunk.

Q: Does installation require drilling or cutting factory interior panels?

The mounting brackets bolt directly into factory threaded attachment points located behind the interior trim. No drilling, sheet metal cutting, or permanent modifications are required.

Q: Does this basket kit fit the INEOS Grenadier Quartermaster pickup?

This storage kit is engineered specifically for the enclosed interior cargo sidewalls of the Grenadier Station Wagon (2023-2026). The Quartermaster pickup features an open truck bed with distinct bed-rail geometry and is not compatible with this interior bracket kit.

Q: How does the Inverter Fit basket maintain access to the 400W outlet?

The Inverter Fit variant incorporates a stepped relief cutout in the lower aluminum floor. This profile clears the raised housing, leaving the factory 12V / 400W power outlet and three-prong plug accessible for field electronics.
