Need a part for this truck?
This is the most useful next step for many owners. Call or text Rocky Mountain Mini Trucks at (801) 382-9540 with your chassis code, the part you need and a photo if possible. We can help identify hard-to-find OEM parts, maintenance items and compatible replacements. Parts can ship nationwide.
Before ordering: identify the truck correctly
Kei-truck parts fitment can change within a generation. Record the complete chassis code and serial, engine code, 2WD/4WD configuration, transmission type and any dump/Jumbo/special-body equipment. A clear photo of the ID plate and the old part is often more useful than model year alone.
Looking for a kei truck?
RMMT imports and sources kei trucks for customers nationwide. If you are researching this generation before buying, tell us the chassis, options, color and intended use and we can watch for a good candidate rather than forcing a one-size-fits-all truck.
Mountain West service
If you are in Utah or the Mountain West and need hands-on help, call or text (801) 382-9540. RMMT is building specialist service capability around the same chassis families covered in this library.
