Bobcat T870 Track Options Explained
The Bobcat T870 is available in two undercarriage configurations that use different track sizes. This is the most common fitment mistake on this machine. The torsion mount T870 uses 450x86x60 (60 links). The suspension mount T870 uses 450x86x58 (58 links). These are NOT interchangeable — a 60-link track will not fit the suspension frame and vice versa.

Suspension: 450x86x58 · Torsion: 450x86x60
What size rubber track does the Bobcat T870 use?
The T870 must be identified by undercarriage configuration. TrackTECH's live machine collections separate 450x86x58 for suspension from 450x86x60 for torsion mount. These are different link counts and are not interchangeable.
Shop the exact configuration: T870 Suspension — 450x86x58 or T870 Torsion Mount — 450x86x60.
Can the Bobcat T870 run wide and narrow tracks?
No, but you must identify torsion vs suspension. Check your serial number or count the links on your existing track — 60 links = torsion, 58 links = suspension.
What is the best tread pattern for the Bobcat T870?
C-Block for general construction. Zig-Zag for mixed terrain. The T870's 100-hp engine handles all tread patterns well. X-Terrain available on both the 60-link and 58-link sizes.
Compare all patterns in our tread pattern guide.
How long do Bobcat T870 rubber tracks last?
1,200 to 1,800 hours. The T870 is being replaced by the Bobcat T86-2 Pro with 115 hp — same track sizes apply.
Maximize track life with track tension set to the Bobcat service procedure, daily undercarriage cleaning, and matching your tread pattern to your primary work surface. See our maintenance guide for the full checklist.
What undercarriage parts should I replace with new tracks?
Inspect sprockets, front and rear idlers, bottom rollers, alignment and tension at every track swap. Replace components by measured wear and Bobcat service limits rather than a fixed track-change interval. Worn or seized components can damage new tracks prematurely.
How much do Bobcat T870 replacement tracks cost?
Aftermarket OEM-spec tracks from TrackTECH cost significantly less than dealer OEM pricing while matching factory quality specs — continuous steel cord, anti-abrasion virgin rubber, and drop-forged steel guides. All tracks include free shipping and a 24-month warranty. See our OEM vs aftermarket comparison for details.

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.
