Rubber Track Sizing: Get the Fitment Right Before You Buy
Rubber track fitment starts with the size molded into the track, but the three numbers are only part of the story. Width, pitch, link count, guide type, and the machine's exact undercarriage configuration all need to agree.
How Rubber Track Sizes Are Written
Most rubber tracks are identified as width × pitch × links. For example, 450×86×58 means a 450mm-wide track, an 86mm pitch, and 58 links.
- Width: the overall width of the track.
- Pitch: the center-to-center spacing of the drive links.
- Links: the total number of drive links around the track.
Those measurements must match the machine's undercarriage geometry. A track that is close is not necessarily interchangeable.
Guide Type Is the Fourth Fitment Check
Two tracks can share the same width, pitch, and link count and still use different internal guide geometry. That guide profile controls how the track runs through the rollers, idlers, and sprocket.
Common guide families include Block (B), N/K, W, and Takeuchi-specific T configurations. See our Rubber Track Guide Types Explained article for a deeper breakdown.
Can the Same Machine Use More Than One Track Width?
Sometimes. Certain compact track loaders have more than one verified width configuration, while others do not. A wider track generally increases flotation; a narrower track can reduce overall machine width and may be more practical for transport or firm-ground work.
Do not change width based on pitch and link count alone. The alternate width must be confirmed for the machine's undercarriage and guide configuration.

How to Confirm Your Track Size
- Read the existing track. Look for the molded or stamped size on the rubber.
- Confirm the machine. Have the make, model, and serial number or undercarriage configuration available.
- Verify the guide type. Do not assume two tracks with the same three-number size share the same internal guide.
- Measure if needed. If the marking is gone, measure the width and pitch and count the links.
- Use governed fitment data. Check the TrackTECH Rubber Track Finder or contact us before ordering if anything conflicts.

Confirm Fitment Before It Ships
The fastest way to avoid a return is to verify the full configuration before ordering. Use the Rubber Track Finder, or call TrackTECH at (850) 816-7898 with your make, model, and current track size.
