## NordicTrack X32i NTL39221.5 Treadmill Incline Lift Motor

The NordicTrack X32i NTL39221.5 treadmill incline lift motor is a preowned replacement part for the incline system in a compatible NordicTrack X32i treadmill. It helps support the machine’s incline-lifting function, making it a practical option when the original incline motor needs replacement. This component may suit treadmill owners, repair technicians, and fitness equipment service providers working on the specified NordicTrack model.

Product Details and Benefits

This product is an incline lift motor from NordicTrack’s treadmill parts range. It is identified with the motor markings **SJJ4-4** and **415174**. The listed part number is **425791**, and the store SKU is **FP403**.

As part of a treadmill’s incline assembly, the motor provides the powered movement used to raise and lower the running deck. Replacing a faulty or worn incline motor can help address an incline system that no longer moves as expected. It may also help restore the treadmill’s intended incline function when the rest of the lift assembly and control system remain serviceable.

The motor is sold in **preowned condition**. Because it comes from previously used equipment, it may show signs of handling or prior installation. Buyers should review the product photos and compare the motor’s markings and connectors with the part currently installed on their treadmill before ordering.

No additional specifications, such as dimensions, motor voltage, material, color, or package contents, are provided with this listing. The product should therefore be selected by matching the equipment model and identification numbers rather than relying on appearance alone.
