Forged 4x4 Bought a Subaru Sambar to Build Into an Off Road Monster
The Forged 4x4 team, known for building and giving away full size overland rigs, just bought a Subaru Sambar kei truck for their wildest build yet. Here is why off road builders are ditching big trucks for 660cc Japanese workhorses.
A team that has spent years building six figure overland rigs, lifted Jeeps, and kitted out Tacomas just walked into the shop with a 660cc Japanese micro truck and a plan to turn it into something absurd. Forged 4x4, the overlanding brand and YouTube channel that has given away half a million dollars in custom built 4x4 vehicles since 2019, decided their next project would cost less than the winch on most of their previous builds.
That project is a Subaru Sambar kei truck. And the fact that a crew this deep in the full size overland world chose a kei truck says everything about where the off road build scene is heading in 2026.
Why Off Road Builders Are Going Small
The kei truck off road build trend is not new. Channels like Grind Hard Plumbing Co put massive tires on a 6x6 kei truck. Off Road Xtreme documented a full Daihatsu Hijet build from the mountains of southern Japan. And the r/keitruck community has become a showcase of increasingly ambitious off road conversions, from simple lift kits to full suspension overhauls with 30 inch tires.
What changed is who is building them. Five years ago, kei truck builds were exclusively the domain of JDM enthusiasts and farmers who needed cheap utility. Today, the builds are coming from professional overlanding shops, offroad fabricators, and content creators who could build on any platform they want, and are deliberately choosing a truck that weighs less than the empty bed of a Ford F-250.
The appeal makes sense once you think about it. A full size overland build on a Tacoma or 4Runner starts at $50,000 before a single mod. A kei truck lands in your driveway for $5,000 to $8,000 including import costs, leaving a massive budget for mods, fabrication, and the kind of creative builds that actually get attention. As TFLtruck noted, a lighter truck actually handles rough terrain better in many scenarios because it does not get bogged down under its own weight.
Why the Sambar Is the Builder's Choice
Forged 4x4 could have picked any kei truck. The Suzuki Carry is the most popular and has the best parts availability. The Daihatsu Hijet has the longest production history. But they went with the Sambar, and that choice is deliberate.
The Sambar's rear engine layout gives it a weight distribution that no other kei truck can match. With the EN07 engine sitting under the bed behind the rear axle, the Sambar puts more weight over the driven wheels than any front engine cab over design. That means better traction climbing hills, better grip in mud, and a more planted feel on uneven terrain. The trade off is rear engine access difficulty, something builders accept because the traction benefits outweigh the maintenance inconvenience.
The Sambar also benefits from Subaru's DNA. The EN07 is a miniature version of the same flat engine philosophy that powers the WRX and Outback. Supercharged EN07T variants make 52 to 58 hp, which is near the kei class maximum, and the four wheel drive system uses a proper transfer case with high and low range. Compared to the part time 4WD on most Carries and Hijets, the Sambar's system offers more sophisticated traction management straight from the factory.
According to JDMBuySell's Sambar guide, used Sambars at auction run ¥100,000 to ¥400,000 ($700 to $2,700) in Japan before shipping. That puts the landed cost around $4,000 to $7,000, leaving plenty of budget for the build.
The Build Checklist Every Kei Truck Off Roader Needs
Whether you are building a Sambar like Forged 4x4 or working with any other model, the off road mods guide covers the full breakdown. The essentials have not changed, but the aftermarket has exploded over the past two years.
A 2 to 3 inch lift kit is the foundation. Stock kei trucks sit about 6 inches off the ground, which is barely enough for a gravel road. Oiwa Garage now stocks model specific lift kits for the Carry, Hijet, Sambar, and Acty, and Rough Country recently entered the kei truck market with kits designed specifically for Japanese mini trucks. Once the lift is on, upgrade to 13 or 14 inch wheels with aggressive all terrain or mud terrain tires. The factory 12 inch steelies with 145mm road tires are designed for Osaka traffic, not trail running.

Skid plates, a front bumper with winch mount, and LED lighting round out the protection and visibility package. The total bill for a properly equipped off road kei truck: $1,500 to $3,000 on top of the truck itself. That is the cost of a set of tires for a Tacoma.
What This Means for the Market
Builds like this one from Forged 4x4 do more than generate YouTube views. They normalize kei trucks in a community that has historically been obsessed with the biggest, most powerful platform available. When a legitimate overlanding brand with a track record of building $80,000 rigs picks a Sambar as their next project, it tells the audience that these trucks are not toys. They are viable platforms.
The downstream effects are already visible. Kei truck import numbers have tripled since 2020, parts availability from suppliers like Amayama has expanded, and the aftermarket is growing fast enough that mainstream brands are entering the space. With over 30 states now allowing street legal registration, the practical barriers to ownership keep shrinking.
If you are considering your own build, start with the pre-purchase checklist and the parts sourcing guide. Check the dealer directory for shops near you that already have build experience.
The era of the $60,000 overland build is not over. But the era of the $10,000 overland build that does 90% of the same job just got a lot more interesting.
