CAT 279D Heavy-Duty Rubber Tracks | 450x86x56Heavy-duty 450x86x56 replacement rubber tracks for the CAT 279D Compact Track Loader, built for dependable traction, stable ground contact, and productive operation across grading, loading, pushing, cleanup, earthmoving, and mixed-terrain work.450 mm Footprint & Ground PerformanceThe wide 450 mm footprint spreads machine weight across a broad contact patch for improved flotation, stable travel, and reduced surface disturbance on soft or loose ground. Tread geometry then determines how the machine balances bite, cleanout, ride quality, and wear across changing jobsite conditions.Choose the Tread for the Work C-Block: Stable all-around traction and predictable steering across dirt, gravel, hardpack, rock, concrete, and general construction. Multi-Bar: High-contact tread for smooth travel, consistent traction, and reduced vibration across dirt, sand, packed ground, wet conditions, and hard flat surfaces. Zig-Zag: Aggressive stepped tread with multiple biting edges and open cleanout channels for mud, wet clay, snow, loose soil, and slopes. X-Terrain: Open, aggressive tread for loose, uneven, and severe off-road conditions where cleanout and ground engagement are the priority. Staggered Block: Balanced block layout for dependable traction, stable travel, and smooth ground contact across dirt, gravel, clay, and mixed terrain. Z-Max: High-bite tread for demanding pushing, grading, and off-road work where strong ground engagement matters most. All-Terrain: Versatile mixed-surface design balancing traction, stability, ride quality, and wear. Heavy-Duty Track ConstructionAdvanced abrasion-resistant rubber, a continuous steel-cord core, and drop-forged, heat-treated steel links provide strength under repeated pushing, turning, grading, loading, and travel. Heavy-duty construction uses approximately 30% more rubber than standard-duty replacements through high-wear areas to help resist stretching, cuts, tearing, chunking, and premature abrasion.Undercarriage & Track LifeInspect sprockets, rollers, idlers, alignment, and track tension before installation. Worn components or incorrect tension can accelerate wear and reduce service life. Set final track tension to Caterpillar service specifications after installation.Warranty & SupportNationwide fulfillment is available, backed by a 24-month warranty against manufacturing defects and application support when needed.Tested.
