CAT compact track loaders in TrackTECH's current catalog progress through several distinct 86 mm-pitch track families. The model name matters because link count and width change as you move up the lineup.
CAT CTL track-size chart
| Model | Current TrackTECH cataloged size(s) | Machine collection |
|---|---|---|
| 259D3 | 320x86x53, 400x86x53 | 259D3 |
| 279D | 400x86x56, 450x86x56 | 279D |
| 289D3 | 450x86x56 | 289D3 |
| 299D3 | 450x86x60 | 299D3 |
259D3: 53-link family
The 259D3 currently spans 320 and 400 mm widths on the 86x53 family. Match the installed machine before changing width.
279D / 289D3: 56-link family
The 279D live catalog contains 400 and 450 mm widths on 86x56. The 289D3 currently centers on 450x86x56. This is a good example of why model-specific catalog data is more useful than a generic “CAT 56-link” chart.
299D3: 60-link family
The current 299D3 collection centers on 450x86x60. The 299D3 XE has its own live machine collection and should not be assumed identical without verifying the exact model designation.
CAT undercarriage part numbers
CAT collections can overlap on component numbers such as sprockets, idlers and rollers, but machine-specific verification still matters. The part number stamped on the component and the exact machine designation are stronger evidence than track size alone.
Tread selection and operating surface
Hard-pack work usually benefits from stable block patterns; mixed dirt favors balanced patterns such as Zig-Zag/All-Terrain; softer ground favors open patterns like Multi-Bar; severe loose terrain may justify more aggressive options where offered.
Before installing new rubber
Check sprocket tooth profile, idler play, roller condition, tensioner travel and track-frame alignment. If the old belt ratcheted or repeatedly de-tracked, diagnose that before fitting the replacement.

Quick Buying Answers
Which rubber track rides the smoothest? For a verified fitment that offers it, Multi-Bar is usually the first tread to compare when lower vibration and smoother travel matter most.
Which track lasts longest on pavement? On asphalt and other hard, relatively flat surfaces, Multi-Bar is a strong first choice because it spreads contact across more tread bars. For harsher abrasive work such as broken concrete, rock, or demolition debris, compare a heavier C-Block or Staggered Block pattern instead.
What is the best track for paving? Start with Multi-Bar when ride quality, steady contact, and hard-surface travel are priorities. Confirm that the exact pattern is available for your machine before ordering.
What is the most affordable track? Price depends on the exact width, pitch, link count, guide type, and tread. Once fitment is confirmed, compare the live compatible options rather than changing dimensions just to save money.
What about mud, snow, or soft ground? Zig-Zag is usually the better pattern to compare when cleanout and bite matter more than pavement manners.
