A 400 mm and 450 mm rubber track can share the same pitch and link count and still not be interchangeable on every machine.
Why width is not just a preference
Track width affects clearance around the roller frame, idlers and machine body. It also changes flotation and ground pressure. Some CTLs are genuinely cataloged in both widths; others are not.
What must stay compatible
- Pitch
- Link count
- Drive-lug and guide geometry
- Sprocket engagement
- Roller and idler alignment
- Side clearance through the undercarriage
When a width change may be valid
A width change is reasonable only when that alternative is verified for the specific model and undercarriage configuration. TrackTECH's live catalog contains examples of machines with confirmed 400/450 mm options, but that is model-specific evidence—not a universal conversion rule.
When not to change
Do not convert because the wider track is on sale, because another machine uses it, or because pitch × links matches. Verify the installed configuration first.

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.
