Complete W463 Six-Wheel Conversion Package
The W463 6×6 conversion kit by Kubay Design is a comprehensive package developed for transforming the classic Mercedes-Benz G-Class platform into a three-axle, six-wheel vehicle. It brings together the principal body, rear-frame, suspension, driveline, wheel and exterior components required for a complete conversion project, allowing professional builders to source the core system from one supplier rather than assembling unrelated parts individually.
This package is positioned as the most accessible complete six-wheel solution in the Kubay Design range. It is intended for experienced tuning workshops, vehicle constructors and customers planning a professionally managed build. The conversion changes the vehicle’s structure, dimensions, suspension layout, braking connections and driveline configuration. Installation therefore requires appropriate fabrication equipment, chassis-measurement capability and qualified specialists familiar with modified vehicles.
The current product specification includes an extended rear body, reinforced steel frame elements, a middle axle assembly, transfer components, six wheels, suspension upgrades and selected carbon fiber exterior parts. The package is designed specifically around the classic Mercedes-Benz G-Class W463; compatibility with an individual donor vehicle must still be confirmed by production year, VIN, engine, transmission, axle type and existing modifications before ordering.
What the W463 Conversion Kit Includes
The package combines structural parts with exterior finishing components. Its purpose is to provide the main elements for extending the donor vehicle and creating the recognizable proportions of a G-Class 6×6 conversion. Exact preparation, welding, alignment, finishing and homologation work remain dependent on the donor vehicle and the installation workshop.
Extended Body and Rear Frame Components
- Extended rear body structure for the six-wheel configuration
- Heavy-duty steel rear frame section
- Reinforced upper body arc supporting the extended body layout
- Three rear side windows integrated into the extended body design
- Rear side panels with hydrophobic yacht-style wood detailing
- Front and rear reinforced skid plates
The rear frame and body elements establish the physical foundation of the conversion. Their installation involves accurate positioning in relation to the original chassis, body shell, doors, axle centers and cargo area. Before assembly begins, the donor vehicle should be measured for structural alignment and inspected for corrosion, previous repairs or deformation that could affect the finished result.
The supplied rear side panels incorporate yacht-style wood detailing intended to give the cargo area a more exclusive appearance. The source information does not specify the wood species, coating system, load-bed dimensions, maximum payload or long-term maintenance procedure. These details should be confirmed when the build will be used for regular cargo transport or exposed to demanding weather conditions.
Carbon Fiber Exterior Components
- Wide carbon fiber fender flares
- Carbon fiber roof spoiler
- Long carbon fiber side body mouldings
The included carbon fiber body kit elements visually connect the extended rear section with the original W463 body. The wider fender flares provide coverage for the enlarged wheel track, while the roof spoiler and elongated side mouldings complete the exterior profile. Final fit, panel gaps and surface finish depend on correct body preparation and professional installation.
Carbon components should be inspected and test-fitted before painting, clear coating or final assembly. The page does not state the weave pattern, finish option, manufacturing method or whether every mounting fastener is included. Buyers requiring a particular carbon appearance should confirm these points with Kubay Design before the kit enters production or shipping preparation.
Six-Wheel and Tire Package
- Six heavy-duty rims
- Six off-road tires
- Eleven-centimeter wheel spacers for the wider track
The complete wheel package gives the finished vehicle its six-wheel stance and supports the wider body configuration. Rim diameter, width, offset, tire dimensions, load index, tread design and brand are not listed in the supplied product description. They should be confirmed for the intended vehicle weight, suspension height, local road regulations and planned use.
The stated 11 cm wheel spacers increase track width and must be installed with suitable fastening hardware and correct torque procedures. Wheel-bearing load, steering geometry, tire clearance and body coverage should be checked during assembly. No assumption should be made that standard W463 alignment values remain applicable after the chassis, axle and track-width changes.
Suspension and Driveline Components
The six-wheel conversion requires more than an extended exterior body. This package includes the principal suspension and driveline parts listed on the current product page for establishing the three-axle layout.
Lifted Suspension Equipment
- High-performance shock absorbers with heavy-duty springs
- Precision suspension spacers for additional ride height
- Universal joints and silentblocks
- Brake-system fittings and hydraulic connectors
The shock absorbers, springs and spacers support the raised configuration and additional vehicle length. Final ride height, spring rate, shock specification, suspension travel and axle-load limits are not stated on the page. These values should be confirmed against the donor vehicle, finished curb weight and intended use before installation.
Brake lines, hydraulic connections, universal joints and silentblocks are included as supporting conversion components. Their exact quantities, dimensions and application points are not itemized in the source description. The installer should prepare a complete build plan and verify every connection before dismantling the donor vehicle.
Middle Axle and Transfer Components
- Standard middle axle assembly
- Transfer case for the extended driveline layout
- Required driveshaft components listed with the package
The middle axle, transfer case and driveshafts form the core of the three-axle driveline arrangement described for this package. However, the current listing does not identify the axle manufacturer, differential ratio, locking mechanism, transfer-case model, torque rating or compatibility with specific engines and transmissions.
These specifications are essential for a technically correct build. Differential ratios across the axles must be compatible, driveshaft angles must be measured, and the completed driveline must be checked for vibration, clearance and operating temperature. Customers should request a detailed technical confirmation for their donor vehicle before placing the order.
The package description does not list portal axles. A buyer should not interpret the raised stance or six-wheel layout as confirmation that portal hubs are included. Any portal-axle configuration, alternative transfer case or upgraded axle package should be discussed as a separate project specification.
Professional Installation and Build Planning
Kubay Design offers optional professional assembly at its workshop in Poland. The current product page lists the installation service at $20,000 and gives an approximate build time of two months. Both figures should be confirmed before purchase because the donor vehicle’s condition, requested customization, component availability and technical approval requirements can affect the final quotation and schedule.
Installation of the W463 6×6 conversion kit is not comparable to fitting a conventional exterior body kit. The process may involve structural cutting, frame extension, welding, corrosion protection, axle positioning, suspension setup, driveline fabrication, brake-system modification, body alignment, electrical work and final calibration.
Recommended Donor Vehicle Inspection
- Confirm the VIN, production year and W463 chassis identity
- Inspect the chassis and body for corrosion or previous structural repairs
- Record engine, transmission, transfer-case and axle specifications
- Measure chassis geometry and existing suspension height
- Check braking, steering, cooling and electrical systems
- Review registration requirements before structural work begins
A technically sound donor vehicle reduces uncertainty during the conversion. Existing frame damage, corrosion, non-standard axles or undocumented repairs can change the work required. The price of the kit does not by itself confirm the total completed-project cost, since paint, labor, donor-vehicle repairs, interior work, certification, taxes and transport may be separate.
Workshop Requirements
Independent installation should be carried out only by a workshop equipped for structural vehicle modification. A suitable facility should be able to measure the chassis, control welding distortion, align three axles, manufacture or adjust driveline components, route hydraulic lines safely and inspect the completed vehicle under load.
After assembly, the vehicle should undergo alignment, brake testing, driveline inspection and a controlled road test. Depending on the destination country, an engineering report, individual vehicle approval, axle-load documentation or updated registration may be required. Kubay Design cannot replace local regulatory advice, so buyers should confirm the applicable process with the competent authority before commissioning the project.
Optional Interior and Exterior Customization
The base package can be expanded with additional customization. The current listing identifies a full luxury interior conversion priced at $24,000, with custom configurations available. It also refers to extended carbon detailing, aerodynamic upgrades, exclusive lighting, wheel customization and bespoke trim options.
These upgrades are not automatically included in the base G-Class 6×6 conversion. Their specification and price should be agreed separately. Interior layouts, upholstery materials, seat functions, lighting design and trim combinations depend on the customer brief and donor vehicle.
Customers planning a complete turnkey build should define the exterior color, carbon finish, wheel design, cabin layout, cargo-bed treatment and intended use at the beginning of the project. Early specification reduces the risk of repeated fabrication or incompatible finishing decisions later in the build.
W463 Fitment and Generation Differences
This conversion package is developed for the classic W463 G-Class produced from 1990 through 2018. It is not designed as a direct-fit system for the later W463A generation introduced for the 2018/2019 model cycle or for the W465 generation introduced from 2024.
Classic W463 Identification
Classic W463 vehicles retain the earlier body and chassis architecture, traditional dashboard layout and generation-specific front suspension and mounting points. Depending on model year, they can also be recognized by the older headlight surrounds, exterior mirror design, door hardware and cabin controls. Facelift updates changed individual components during the long production period, so appearance alone is not sufficient for ordering structural parts.
Why W463A and W465 Parts Differ
W463A and W465 vehicles use different body dimensions, chassis structures, suspension geometry, electronics and component mounting locations. Structural conversion parts produced for the classic Mercedes-Benz G-Class W463 should not be assumed to fit these later generations. Even when exterior styling appears similar, frame and suspension components are not interchangeable without project-specific engineering.
Always submit the VIN, production date and clear donor-vehicle photographs before ordering. Engine, transmission and axle information should also be provided because the W463 platform includes numerous model and drivetrain combinations. Kubay Design can then review the supplied information and clarify whether additional or alternative parts may be required.
Shipping, Packaging and International Orders
The listing provides worldwide delivery options. Full conversion packages can be transported by container, while selected components may be eligible for UPS or DHL express delivery. The page states an estimated express transit time of four to seven business days and mentions insured packaging with tracking.
Transit time is separate from production, order preparation, export documentation and customs clearance. A complete W463 6×6 conversion kit contains large and heavy structural components, so the final shipping method and cost depend on destination, package dimensions and available freight service. Import duties, local taxes, port fees and customs charges may also apply.
Before payment, request a written quotation identifying the included components, optional services, production status, shipping method, delivery terms and destination costs. Review the Shipping Policy, Payment Rules and Refund Policy, especially because custom-made and project-specific products may be subject to different cancellation or return conditions.
