Komatsu Parts

Published: July 3, 2026  |  By FP Smith Parts & Equipment

Millions of parts & components physically stocked — new OEM surplus, quality used, and reconditioned — ready for same-day shipping from our Fairfield facility.

With decades of hands-on experience supporting some of the toughest machines in construction and mining, FP Smith Parts & Equipment has become one of the most reliable sources for Komatsu parts on the West Coast.

Since 1947, our family-owned business has maintained one of the largest physical inventories of new OEM surplus, quality used, and reconditioned Komatsu components — not just listed online, but actually stocked in our 20-acre facility at 3190 Ramsey Rd., Fairfield, California.

Why Choose FP Smith for Komatsu Parts?

Our team’s deep knowledge of Komatsu models helps customers get the right part the first time — whether you operate modern excavators or legacy dozers still working hard on job sites across California and beyond.
