# Spirit Fitness XT-9 Treadmill Main Drive Belt (MX301)
The Spirit Fitness XT-9 Treadmill Main Drive Belt is a replacement drive belt for the Spirit Fitness XT-9 treadmill.

Product Details and Benefits
This product is a treadmill main drive belt identified by part number and SKU **MX301**. It is made for use in the drive system of a **Spirit Fitness XT-9 treadmill**. As a replacement component, it provides the belt needed to transfer motion from the treadmill’s motor to the running-belt system.
A worn drive belt can affect treadmill operation and may contribute to slipping, inconsistent movement, or a loss of drive. Replacing the belt with the correct model-specific part helps maintain the intended mechanical connection inside the treadmill. The belt is supplied as an individual replacement part for repair or maintenance.
The product listing identifies this item as the **Spirit Fitness XT-9 Treadmill Main Drive Belt (MX301)**. The listed barcode is also **MX301**. These identifiers can help you compare the part with your existing belt, service records, or treadmill parts information before placing an order.
Compatibility and Applications
This main drive belt is designed for the following equipment:
- **Brand:** Spirit Fitness
- **Treadmill model:** XT-9
- **Part name:** Main drive belt
- **Part number/SKU:** MX301
- **Equipment type:** Treadmill
The belt is intended to replace the original main drive belt used in a Spirit Fitness XT-9 treadmill. It is suitable for treadmill repair and replacement-part applications where the existing drive belt requires renewal.
Compatibility should be based on the complete treadmill model, not only the general equipment type. A belt made for one treadmill model may not fit another model, even when both machines use similar drive systems.
## Why Choose This Replacement Belt
Choosing the correct replacement treadmill drive belt can help you address a failed or worn drive-system component without replacing the entire treadmill. The MX301 provides a model-specific replacement option for owners and service technicians working on a Spirit Fitness XT-9 treadmill.
Using the correct part number also makes ordering and parts identification easier. Before removing the old belt, compare its markings and the treadmill’s model information with the details shown here. This can reduce the risk of ordering an incompatible component.

The product listing does not provide belt dimensions, material details, installation instructions, package quantity, condition, or warranty information. Check these requirements if they are important for your repair.
The listed product record also includes the reference **9068810611000583REV00**. Use the treadmill model, existing part information, and MX301 identifier together when verifying compatibility. This product is the main drive belt only; other treadmill components are not identified as included.
