What Is a 6×6 Kei Truck?
A standard kei truck has a 4×4 drivetrain, meaning power is delivered to all four wheels. A 6×6 kei truck goes a step further, adding an extra axle for six wheels and full-time or selectable six-wheel drive.
Key features of 6×6 kei trucks include:
- Extended chassis to fit a third axle
- Three differential system for 6-wheel traction
- Heavy-duty suspension upgrades
- Higher payload capacity compared to stock 4×4 kei trucks
- Often lifted with off-road tires
These conversions are done by specialty shops or custom builders in Japan and the U.S., making them rare and highly sought after.
Why Buy a 6×6 Kei Truck?
While a regular kei truck is versatile, a 6×6 kei truck takes capability to another level.
- Extreme Off-Road Capability – Six-wheel traction provides unmatched performance on mud, snow, or rocky trails.
- Higher Payload Capacity – Extra axle means more stability and load support.
- Custom Build Appeal – Owning a 6×6 kei truck guarantees attention at car shows or off-road meets.
- Farm & Ranch Utility – Perfect for hauling feed, logs, or supplies in rough terrain.
- Unique Collectible – Since they’re rare, 6×6 kei trucks have strong resale value.
