Heavy-Duty Komatsu Rubber Tracks

Direct replacement rubber tracks for Komatsu compact equipment are built for traction, durability, and long service life across demanding jobsite conditions. These replacement tracks support compact track loaders, mini excavators, skid steers, and mini track loaders working in dirt, clay, gravel, demolition debris, grading, utility work, land clearing, and mixed terrain.

Built for Strength and Uptime

Heavy-duty rubber construction, continuous steel cord reinforcement, and durable steel link geometry help support stable tracking, reduced stretching, and dependable performance under load. Wear-resistant rubber compounds help resist tearing, chunking, cracking, and premature wear through long operating hours.

Precision-Aligned Undercarriage Fit

Machine-specific sizing, guide lug alignment, and link spacing are designed to support proper sprocket engagement and smooth travel across undercarriage systems. Proper track geometry helps reduce vibration, protect rollers and idlers, and keep the machine working with consistent control.

Popular Machine Applications

Popular Komatsu rubber track applications include compact track loaders, mini excavators, and tracked utility machines where traction, ride quality, undercarriage protection, and uptime matter.

Contractor-Grade Replacement Value

Premium replacement rubber tracks deliver direct replacement performance, fast freight delivery, and a 24-month warranty against defects in materials and workmanship without inflated dealership pricing.

Frequently Asked Questions

What Komatsu parts does TrackTECH carry?

TrackTECH carries replacement undercarriage parts for Komatsu compact equipment: rubber tracks, drive sprockets, front idlers, top and bottom rollers — OEM-fit specifications with continuous steel cord construction. 329 Komatsu-fitment SKUs in stock.

How do I confirm fitment for my Komatsu machine?

Three ways to verify before ordering:

  1. Match the size on your existing track — width × pitch × link count is stamped or embossed on the rubber
  2. Use the Rubber Track Finder — filter by Komatsu and your model
  3. Call (850) 816-7898 — our team verifies fitment by serial number before any order ships

For help measuring, see How To Measure Rubber Tracks.

Do all Komatsu models use the same track size?

No — track size varies by model and weight class. The most common Komatsu sizes in our catalog are: 300x52.5Nx80, 300x52.5Nx84, 400x72.5Kx72, 230x48x62, 450x83.5Kx74, 300x52.5Nx76. Each product page lists the specific machines it fits. When in doubt, verify with the size stamped on your current track.

Do you carry both Komatsu tracks and undercarriage parts?

Yes. We stock Komatsu-fit rubber tracks alongside drive sprockets, front and rear idlers, and top/bottom rollers — built to OEM specifications so you can replace the full undercarriage from one supplier. See Drive Sprockets, Front Idlers, Rear Idlers, and all undercarriage parts.

What's included with a Komatsu parts order?

Every order includes 24-month warranty against defects in materials and workmanship, free freight to the lower 48, and same-day dispatch on in-stock orders placed before 12 PM CT. Tracks ship as pairs by default; sprockets, idlers, and rollers ship per unit unless ordered otherwise. See Returns & Refunds for the full policy.

Frequently Asked Questions

Common fitment, shipping, and replacement parts questions

What size rubber tracks does Komatsu use?
Komatsu track size varies by model. Give us your model and serial number and we'll confirm the size.
Do Komatsu machines need W-guide or N-guide tracks?
Komatsu PC-series mini excavators use N-guide tracks. Guide lugs are the raised teeth on the inside of the track that straddle the rollers and keep it centered. W (wide) and N (narrow) refer to the spacing of those lugs and must match your machine's undercarriage — it's a fitment requirement, not a performance choice. Most machines run W-guide. N-guide is required on John Deere, Hitachi, Takeuchi mini excavators, Komatsu PC-series, the Case CX55B, and the Kobelco SK55SR. Not sure? Send us your model and serial number and we'll confirm before you order.
Are your Komatsu rubber tracks OEM quality?
Yes. Our tracks are built to OEM dimensions — same width, pitch, link count, and guide profile as your factory track — using high-tensile continuous steel cord and premium rubber compounds. They fit and perform like OEM at dealer-direct pricing.
How long do Komatsu rubber tracks last?
Most rubber tracks last 1,200 to 2,000 hours. Terrain, how the machine is run — counter-rotating and sharp turns wear tracks fast — and proper tension and alignment make the biggest difference. Keep the undercarriage clean and the tracks tensioned to spec and you'll get the most hours out of them.
Do you offer free shipping and a warranty?
Yes to both. Free shipping on every order with no minimums, and every rubber track is backed by a certified 24-month warranty. Tracks ship dealer-direct and ready to work — we stand behind our product.
