Chelsea Truck Co. has long stood at the crossroads of refinement and ruggedness: transforming iconic off-road vehicles into luxury custom statements. While historically centered on Defenders, over the past few years they’ve expanded into customizing the INEOS Grenadier, applying their same philosophy of bespoke elegance and purposeful design.
The Grenadier is, by nature, engineered to be utilitarian and capable. What Chelsea Truck Co. brings is the artistry: signature body styling components, refined touches, and accessories that preserve its off-road ethos while elevating its presence on the road. Their catalog for Grenadier (2023–present) includes exterior parts like hard spare wheel covers, wide arches, quad roof shields with integrated LED lighting, roof wings, grille inserts, and more. Among the standout pieces is their “Series I” body kit, which adds Hammer grille styling, wide arches, and roof wings, marrying aggression with elegance.
Beyond purely cosmetic upgrades, Chelsea’s Grenadier parts aim to be functional. Their quad roof shield not only adds visual distinction but also increases illumination capacity, practical for night driving or remote adventures. Their parts catalog further supports higher-end wheels, custom grilles, spare wheel covers, and more, allowing Grenadier owners to tailor their ride to their specific needs.
The ECD × Chelsea Truck Co. Collaboration
In Florida, ECD Automotive Design has formally joined forces with Chelsea Truck Co. to create a new custom line of Defender and Grenadier builds under their joint brand presence: ECD x CTC, combining ECD’s craftsmanship with Chelsea’s premium components.
This collaboration taps into the strengths of both: Chelsea’s access to body kits, styling, and parts engineering; ECD’s experience in full-vehicle builds, performance integration, interior luxury, and client experience. The result: vehicles that are built holistically with engineering, aesthetics, and refinement in mind.

Chelsea Truck Co.’s expansion into Grenadier is more than brand extension; it signals that the bespoke 4×4 space is evolving beyond purely vintage vehicles, bridging old-world craftsmanship with new-world platforms.
