Harbor Freight has released multiple versions of the Predator 3500 Inverter Generator. While they look almost identical on the outside, the internal design is completely different and the parts are not interchangeable.
👉 The easiest way to tell which version you have is by the location of the battery access door:
Original Version (Model 63584) – Battery door is on the right side of the generator (when facing the control panel).
New Version (Model 71358) – Battery door is on the left side of the generator.
⚠️ Please check your generator before ordering parts. If you order parts for the wrong version, they will not fit. My parts only fit version 63584 with the battery door on the right. Harbor Freight still uses pictures of the older model on their website, packaging, and manuals, so double-check your actual unit.
📸 See the photos in this listing for comparison between the two versions.
