Supply Lines
Three supply lines for every part category: original genuine components, reliable aftermarket replacement parts, and complete ISUZU engine spare parts and assemblies — all at highly competitive prices.
Genuine (OEM)
Components from Hitachi's authorized manufacturing and distribution channels. Full traceability, genuine OEM numbers on every part and the manufacturer's warranty.
The higher cost buys exact fitment and zero compromise on durability. This is the tier we recommend for critical hydraulic and engine components — main pumps, final drives, engines, ECUs and valve blocks — where a failure costs far more than the part itself.
Aftermarket (High Quality)
Brand-name and factory aftermarket parts manufactured to match OEM specifications. Tested for fitment on ZX, EX and UH series machines with the same dimensional tolerances as original units.
The best cost-performance ratio in our catalog. Ideal for routine service items — filters, seals, undercarriage, wear parts and hoses — where the specification is identical and the saving is real on every service cycle.
ISUZU Engine Parts
Complete ISUZU engine spare parts and assemblies for Hitachi excavators — engine internals, consumables and major assemblies all available.
From pistons, liners and injection components to complete engine assemblies — one reliable source for the engine side of your EX and ZAXIS machines.
