I needed a forklift part and wasn’t sure which one fit. They asked for the model and serial number, got back to me quickly, and made sure I ordered the right one. Really helpful.

Frequently Asked Questions
Q: Does this rear differential arrive pre-filled with gear oil? A: No, it ships dry to prevent leakage; you must fill it with the manufacturer-recommended gear oil before operation.
Q: Is this a fully assembled drop-in unit? A: Yes, the differential comes pre-assembled with bearings and seals, so you only need to bolt it in, add oil, and reconnect the axles.
