Mastas Spare Parts
Undercarriage wear is one of the largest running costs on any tracked machine, and it rarely fails on a convenient schedule. Mastas is known as a supplier of undercarriage and heavy-equipment spare parts, the components that grind down first under load: track chains and shoes, rollers and idlers, sprocket segments, and the pins and bushings that hold a chain together. When those go, replacements need to match on dimensions and hardness, not just look close.
Matching those replacements is the whole job. Our cross-reference database of 564,000+ part numbers lets a specialist confirm fitment from a serial number, an old part number, or a photo, then pull the 100% OEM equivalent from 3,300+ parts in stock. With stock in our Ankara and Santa Ana warehouses, free worldwide shipping to any country, dispatch within 1–2 days and typically 5–7 days door-to-door, sourcing wear parts stays simple even when the original supplier is hard to reach.
