A Hand-Built Mercedes G55 AMG 6×6
This 2008 Mercedes G55 AMG 6×6 is a custom-built six-wheel G-Class based on the classic W463 platform. It combines the established character of the G55 with a fully reworked rear chassis, a purpose-built pick-up body and a carefully selected luxury specification. The result is not presented as a factory-produced G 63 AMG 6×6; it is an individually rebuilt vehicle created from a 2008 Mercedes-Benz G55 donor.
The current vehicle specification includes a 5.4-litre V8 petrol engine, an automatic transmission and an indicated mileage of 110,000 kilometres, equivalent to approximately 68,350 miles. The listing describes the vehicle as undamaged. Its black exterior is paired with a brown full-leather interior sourced from a 2015 G63 AMG, creating a restrained contrast between the traditional W463 body shape and a later-generation AMG cabin design.
For buyers looking for a rare completed vehicle rather than a conventional styling package, this W463 6×6 offers a complete build with the drivetrain, chassis, exterior and rear passenger area already configured. Availability, documentation, registration requirements and international delivery arrangements should be confirmed directly with Kubay Design before purchase.
Six-Wheel Chassis and Drivetrain Configuration
Restored frame, body and chassis structure
The conversion required substantially more than extending the exterior body. According to the current specification, the frame, body and chassis were fully restored, with new components used during the rebuild. This work created the structural basis for the extended wheelbase, the additional axle and the rear pick-up section.
A six-wheel conversion places different demands on the vehicle structure than a standard four-wheel W463. The added axle, longer frame and rear body must operate as one coordinated assembly. For this reason, a prospective buyer should request the available build records, current photographs, service information and vehicle-specific documentation rather than relying only on general G-Class specifications.
Original middle axle and adapted braking system
The listing states that an original Mercedes 6×6 middle axle was prepared and fitted to the vehicle. The braking system was also remanufactured and adapted for the six-wheel configuration. These are central elements of the completed build because the additional axle changes the mechanical layout and requires dedicated component integration.
No axle ratios, differential specifications, brake dimensions or electronic-control details are published on the current product page. Kubay Design should therefore confirm these vehicle-specific technical details with an interested buyer where they are relevant to intended road use, servicing or registration in the destination country.
Portal axles with raised suspension
The vehicle is equipped with portal axles and a lift suspension. In a portal-axle layout, the wheel hub sits below the axle centreline, increasing clearance beneath the axle housing without relying only on larger tyres. On this build, the portal configuration also gives the G-Class the elevated stance associated with extreme six-wheel off-road projects.
The product page does not publish final ground-clearance measurements, suspension travel, overall vehicle height or wheel-alignment data. These figures should not be assumed from photographs or from specifications of other G-Class builds. Buyers who need the vehicle for enclosed transport, garage access or a specific operating environment should request current measurements before arranging collection or shipping.
Custom Pick-Up Body and Exterior Details
Rear body built to a one-to-one specification
A defining element of this G-Class 6×6 is the extended rear pick-up body. The listing describes it as built in a 1:1 format to original specifications, giving the conversion the proportions expected from a premium six-wheel G-Wagon rather than the appearance of a simple chassis extension.
The rear deck is finished with yacht-style wood, adding a crafted luxury detail to the utility-inspired pick-up area. This material contrast works with the black bodywork and carbon components without changing the recognisable square profile of the W463. Because natural and yacht-style finishes require appropriate care, the buyer should ask Kubay Design for the recommended maintenance procedure for the installed rear-deck surface.
Carbon fibre body components
The exterior specification includes carbon fibre body parts in the form of fender flares, a hood scoop and a roof spoiler. These elements visually connect the raised six-wheel chassis with the wider body and give the vehicle a more technical AMG-inspired finish.
The current page does not specify the weave pattern, surface finish, manufacturing method or coating used for each carbon component. Those details should therefore be confirmed before purchase if the buyer requires a particular gloss level, exposed weave appearance or future repair specification. Additional W463 exterior components can be explored in the Mercedes-Benz G-Class category.
New wheels and tyres
The rebuild includes new wheels and tyres selected for the completed six-wheel configuration. Their visual role is important, but fitment should also be treated as vehicle-specific because the portal-axle system, suspension height and widened body influence wheel position and clearance.
The product page does not list wheel diameter, width, offset, tyre dimensions, load rating or tyre model. Buyers should request the current specification, especially when planning replacement tyres, long-distance transport or registration in a market with specific wheel and tyre requirements.
Luxury Interior with Increased Rear Space
Brown leather cabin from a 2015 G63 AMG
Inside, the traditional 2008 donor vehicle has been upgraded with a brown full-leather interior sourced from a 2015 G63 AMG. The later AMG cabin components introduce a more contemporary atmosphere while preserving the upright seating position and distinctive architecture associated with the classic G-Class.
Because the interior originates from a later W463 model, the installed specification should be assessed as part of this completed vehicle rather than as a universal interior kit. Controls, wiring, seat functions and trim integration can vary between donor years. The current page does not list every electrical comfort function, so prospective buyers should request a feature demonstration or detailed equipment list where required.
Rear seats moved back by 23 centimetres
The rear seats were repositioned 23 cm farther back to create a more limousine-style passenger area. This change directly addresses one of the practical limitations of the classic G-Class cabin by prioritising rear legroom within the extended body architecture.
The listing does not provide measured rear legroom, seat-angle data, occupancy certification or details of the modified mounting structure. The 23 cm figure refers only to the stated seat relocation. Buyers planning chauffeured use or regular rear-passenger transport should confirm seating functions, belt configuration and applicable local registration requirements before completing the purchase.
W463, W463A and W465 Compatibility
This vehicle is based on the classic W463
This completed car uses a 2008 Mercedes-Benz G-Class W463 as its base. It should not be confused with the substantially redesigned G-Class introduced in 2018, commonly identified in the tuning market as W463A, or with the updated W465 generation introduced from 2024.
The generations retain the recognisable G-Class silhouette, but their body dimensions, chassis architecture, lighting, bumpers, interior structure, electronics and mounting points are not automatically interchangeable. A visible distinction is the cabin: the 2018-generation G-Class is commonly associated with a wide digital cockpit layout, while the original W463 uses the earlier dashboard architecture. The W465 update can be distinguished by its revised front treatment, lighting details and newer interior technology.
Check production year, VIN and installed parts
Model names alone are not sufficient for ordering replacement or conversion components. A vehicle advertised as a G55, G63 or G-Class may belong to a different production period or may already contain parts from another generation. This particular build is a clear example: the base vehicle is a 2008 W463, while the listed leather interior comes from a 2015 G63 AMG.
Before ordering any spare part, body component or upgrade for this car, provide the production year, VIN and photographs of the installed area. For related six-wheel components, visit the G-Class W463 6×6 category. Broader conversion options are available in the G-Class 6×6 collection.
Buy the Completed Car or Commission a Build
Purchase this finished G55 6×6
The listed vehicle is offered as a completed project with the major structural, mechanical, exterior and interior work already performed. This route suits a buyer who wants a distinctive Mercedes G55 AMG 6×6 without first sourcing a donor vehicle and coordinating each stage of a conversion.
Before purchase, confirm current availability, the exact included equipment, service history, supporting documentation and the condition of the vehicle at the time of enquiry. The displayed product price and commercial terms may change, so the live product page and a written quotation from Kubay Design should be treated as the current commercial reference.
Build a similar configuration from your vehicle
Kubay Design can also discuss creating a similar six-wheel configuration using a customer-supplied vehicle. A donor-based project allows the specification to be planned around the selected base car, desired interior, exterior finish and intended use. However, the final scope depends on the donor vehicle and should not be assumed to match every detail of the completed black G55 shown on this page.
A proposed 6×6 conversion should begin with identification of the donor generation, model year, VIN, mechanical condition and registration market. These details determine which structural, drivetrain, suspension, braking, body and electronic work must be assessed. The current listing does not state a universal completion time or fixed specification for commissioned builds, so those points require an individual quotation.
Conversion components for independent projects
The page also states that a kit may be supplied for self-remanufacture. This option is intended for buyers or professional workshops capable of evaluating and completing complex structural and mechanical work. It should not be treated as a simple bolt-on body kit.
The exact kit contents, fabrication requirements, welding work, axle configuration, brake integration, installation documentation and excluded components are not listed on this vehicle page. They must be confirmed in a separate specification before ordering. Independent installation may also affect registration, insurance, inspection and road-use approval, depending on the destination country.
Ordering, Payment and International Logistics
Confirm the vehicle specification before payment
Because this is an individually rebuilt vehicle, the purchase process should include written confirmation of the chassis identity, mileage, engine and transmission, interior specification, installed axle system, wheels, tyres, included accessories and available documentation. Any feature that is essential to the buyer should be included in the final quotation or sales agreement.
Review the current Payment Rules and contact Kubay Design before transferring funds. For return-related conditions, consult the Refund Policy. Vehicle-specific terms may differ from standard parcel-product conditions and should be confirmed in writing.
Plan transport and import requirements
The increased length, height and six-wheel layout may require specialist vehicle transport rather than ordinary automotive delivery. The current listing does not publish packed dimensions, gross transport weight or a fixed delivery quotation. Transport method, loading requirements, insurance, customs documents, duties and destination handling should therefore be agreed for the buyer’s country.
General information is available in the Shipping Policy, but a completed vehicle requires an individual logistics plan. The buyer is responsible for checking local import, registration, inspection, emissions and road-use requirements unless a written agreement states otherwise.
