Overview
The Honda Acty HA4 is the 4WD second-generation Acty truck, built from 1990 to 1999. The Attack trim makes it the only standard Honda Acty with a factory diff-lock and crawler gear. Mid-engine E07A, chain-driven. Entire production run fully US-eligible since 2015.
Engine
Drivetrain
Across its trims, the Honda Acty HA4 is offered with the drivetrain systems below. Availability is trim-dependent — tap any one for a plain-language explainer of how it works and when to use it.
The off-road spec: diff lock and crawler gear
The most capable examples pair a factory rear differential lock with a super-low crawler gear. These solve two different problems — traction versus torque. See diff lock vs low range for which one you actually need.
Note: HA4 is the 4WD second-generation Acty truck. 2WD is HA3. Attack trim adds factory rear diff-lock and ultra-low crawler gear (4WD manual only). Not every HA4 is Attack trim — confirm badge.
Transmission
The Honda Acty HA4 is available with the transmission types below. Tap any one for a full guide including maintenance schedule and common issues.
Manual or automatic?
The manual gives you maximum power from the 660cc engine and is the only way to access diff-lock and low-range trims. The automatic trades some power for convenience. See manual vs automatic for which one you should choose.

- Eligibility
- Eligible now
Earliest examples are eligible to import to the USA now (from March 2015).
- Right-hand drive (RHD)
- AllowedNo federal ban on right-hand-drive vehicles. Most states allow RHD registration with no extra requirements. Confirm with your state DMV as a small number have local rules.
- Taxes
- Most kei trucks are classified as cargo trucks and attract the 25% "chicken tax" import duty on declared value; the 2.5% passenger-vehicle rate applies only if the vehicle is legitimately classified as such — a customs broker's determination, not a buyer's choice. There is no federal VAT or federal sales tax at the border. State sales/use tax and title & registration fees are charged at registration and vary by state. The 25-year rule exempts safety and emissions compliance but does NOT waive the import duty. Budget ocean freight, port-to-door transport, and the customs broker fee separately.
- Registration authority
- NHTSA and EPA handle federal import compliance. Individual state DMV handles title and registration.
