Nissan Forklift — now operating under the UniCarriers brand within the Mitsubishi Logisnext group — was for decades one of the world's top forklift manufacturers. Millions of Nissan forklifts remain in active service globally, prized for their reliable Nissan-manufactured engines and straightforward, serviceable designs.

The rebranding from Nissan to UniCarriers created confusion in the parts market. Many Nissan-branded parts have been renumbered, and some older Nissan-specific parts are officially discontinued. Kingstream maintains a comprehensive database mapping old Nissan part numbers to current UniCarriers equivalents — and sources legacy Nissan parts that the factory no longer supplies.
