Which Kei Trucks Have Low Range?
The short answer
Only two agricultural trims have a factory low-range crawler gear: the Suzuki Carry Nōhan (DA63T/DA62T) and the Honda Acty Attack (HA3/HA4 second-generation only). Both are manual-transmission-only. No automatic kei truck has factory low range.
Low range vs diff-lock — two different problems
Low range (crawler gear)
Solves the speed and torque problem. A Hi-Lo sub-transmission reduces road speed dramatically while multiplying torque. Lets you move at walking pace with full engine power — essential for steep climbs, deep mud, and precision work. Controlled by a separate Hi-Lo lever, independent of the main gearbox.
Differential lock
Solves the traction problem. Forces equal torque to both rear wheels, preventing one from spinning freely while the other gets nothing. Critical when one wheel is on low-traction surface (mud, ice, loose soil) and the other has grip. Engaged with a switch at low speed.
The Nōhan and Attack have both — but they are independent systems. Low range helps you go slowly with maximum torque. The diff-lock helps you maintain traction when one wheel loses grip. For serious off-road work you want both; for steep-slope precision work alone, low range matters most.

No automatic truck has factory low range
The Hi-Lo sub-transmission on the Nōhan and Attack is mechanically integrated with the manual gearbox. There is no automatic version of either agricultural trim, and no kei truck with an automatic transmission offers factory low range. This is a fundamental constraint, not a regional variation.
If a listing describes an "automatic low-range kei truck," the truck has either been modified (aftermarket), the description is wrong, or the low-range system is absent. Always verify the gearbox type and confirm the Hi-Lo lever is present and functional before purchasing any truck sold as having low range.
US import timing for low-range trucks
- Honda Acty HA3/HA4 Attack — Produced 1988–1999. All examples are eligible for US import right now under the 25-year rule. The Attack is available today; the main challenge is finding a clean, well-documented example.
- Suzuki Carry DA63T Nōhan — Produced May 2002–2013. The earliest builds become eligible from May 2027. No DA63T (Nōhan or otherwise) is currently importable to the US under the standard 25-year exemption.
Frequently asked questions
Which kei trucks have a low-range crawler gear?
Only two trims have a factory low-range sub-transmission: the Suzuki Carry Nōhan (DA63T/DA62T agricultural spec) and the Honda Acty Attack (HA3/HA4 second-generation only). Both are manual-transmission-only. No automatic kei truck has a factory low-range crawler gear.
What is the difference between low range and a differential lock?
They solve different problems. Low range (crawler gear) multiplies torque through a Hi-Lo sub-transmission — it lets you move extremely slowly with maximum torque, which is essential for climbing steep terrain, moving through deep mud at walking pace, or precision work at very low speed. A differential lock forces equal torque to both rear wheels, preventing one from spinning freely when the other loses traction. The Nōhan and Attack have both — but they are separate systems with separate functions.
Can a kei truck have a differential lock without low range?
In theory yes, but in practice all factory-equipped kei truck diff-lock trims (Nōhan, Attack) also have low range. The two systems are packaged together on the agricultural specs. If you find a kei truck with a diff-lock but no low range, it is either an unusual factory build or a truck that has had one system removed or never fitted.
Does the Honda Acty HA6/HA7 have low range?
No. The third-generation Acty (HA6/HA7, 1999–2009) uses Real-Time 4WD with no low-range gearing and no diff-lock. For a low-range Acty, you must target the second-generation HA3/HA4 Attack trim (1988–1999), which has been eligible for US import since 2013.
How does the Nōhan low range work?
The Nōhan uses a Hi-Lo sub-transmission integrated into the transfer case. With the main gearbox in any forward gear, the Hi-Lo lever selects high range (normal road driving) or low range (crawler mode). In low range, a set of reduction gears multiplies torque and dramatically reduces road speed. This gives the driver extremely precise throttle control at very low speeds — essential for steep hillsides, soft ground, and precision agricultural work.
