The Daihatsu Hijet S500 and S510 series represent some of the most capable and practical kei trucks ever produced in Japan, and their global popularity has exploded as more enthusiasts and small-scale farmers discover just how versatile these little workhorses can be. Whether you’re running one on a rural property in New Zealand, restoring one in the UK, or keeping a fleet running in the United States, sourcing quality OEM parts outside Japan has historically been a challenge. That’s where tapping directly into the Japanese domestic market changes everything.
Understanding the S500 and S510 Hijet Platform
Daihatsu introduced the S500/S510 Hijet Truck in 2014 as a significant generational leap from the earlier S200/S210 series. The platform split is straightforward: the S500P is the two-wheel drive variant, while the S510P covers four-wheel drive models. Both share a large number of components, but it’s critical to confirm your drivetrain spec before ordering parts — particularly for axle, differential, and brake-related components.
The S500/S510 uses a 660cc KF-VE or KF-VET (turbocharged) engine paired with either a 4-speed automatic or 5-speed manual gearbox. Knowing your exact engine and transmission codes matters when sourcing items like sensors, mounts, and drivetrain hardware. These codes are stamped on the compliance plate and in your vehicle’s log documents.
One important note for international buyers: many genuine used parts listed on Yahoo Auctions Japan are pulled from low-kilometre vehicles entering dismantling yards, meaning quality is often significantly better than what’s available through aftermarket channels in your home country.
Key Parts Categories and What to Watch For
When sourcing Hijet S500/S510 parts from Japan, these are the categories that come up most frequently — and where genuine OEM used parts deliver the best value:
- Rear Axle and Differential Assemblies: For four-wheel drive S510P models, the rear axle housing with drum brakes is a common replacement item, especially on trucks used in demanding conditions. We stock axle housings pulled from related Daihatsu kei truck platforms, including compatible S201P Hijet Truck units with rear drum brake hardware and handbrake cables — these are worth cross-referencing against your S510P specs as component sharing across generations is common with Daihatsu.
- Door Window Regulators and Motors: Window regulator motors fail quietly and are often ignored until the window stops moving entirely. OEM units like the 85710-B2021 regulator motor (front right) pulled from S321V Hijet Cargo models share engineering DNA with the truck platform and are a good indicator of the part quality available through Japanese dismantlers.
- Weather Seals and Rubber Components: Body seals, door rubbers, and hatch weather strips are consumables that degrade faster in UV-heavy or coastal environments. Sourcing NOS (new old stock) or low-use OEM rubber from Japan is almost always superior to generic aftermarket alternatives that harden quickly.
- Electrical Components: Flasher relays, indicator units, and wiring harness sections are increasingly difficult to find outside Japan. Part numbers like 81980-87203 from related Daihatsu models can sometimes cross-reference to Hijet applications — always verify with your chassis number.
Practical Tips for Buying Japanese Kei Truck Parts Internationally
Navigating the Japanese used parts market is easier than it used to be, but there are still a few things that will save you time and money:
- Always use your chassis number (VIN): For Hijet trucks, the chassis number confirms your exact spec — 2WD vs 4WD, AC vs non-AC, and cab configuration. This matters enormously for parts like axle assemblies and brake components.
- Cross-reference across the Daihatsu family: The Hijet shares significant parts with the Atrai Wagon, Hijet Cargo, and even older Midget II models in some categories. Experienced importers know that a part listed under an S220G Atrai or S321V Cargo may be a direct fit — checking OEM part numbers is the key.
- Inspect listing photos carefully: Reputable Japanese dismantlers photograph parts thoroughly. Look for original part number stickers, check rubber condition on seals, and confirm connector types on electrical components before purchasing.
- Factor in shipping weight for axle and drivetrain parts: Heavy items like rear axle housings incur significant international freight costs. Consolidating orders where possible brings the per-part shipping cost down considerably.
- Buy OEM over aftermarket where possible: For kei trucks used in working conditions, genuine Daihatsu parts simply last longer and fit correctly the first time.
