Frequently Asked Questions

Common fitment, shipping, and rubber track replacement questions

What size rubber track fits the CAT 279D?
The CAT 279D uses a 450x86x56 rubber track. TrackTECH carries it in C-Block, Multi-Bar, and Zig-Zag treads, built to OEM fitment and backed by a certified 24-month warranty.
How long will rubber tracks last on a CAT 279D?
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.
Are your CAT 279D tracks OEM fitment?
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.
Which tread should I run on my CAT 279D?
Match it to your ground: C-Block for hard, abrasive surfaces with the smoothest ride; Multi-Bar for mud and soft soil; Zig-Zag as the all-around standard; X-Terrain for rock and debris; and Z-Max for land clearing, mulching, and land management.
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.
