Find the Right Aftermarket Komatsu Part for Your Equipment

Finding the right Komatsu parts shouldn’t be complicated, overpriced, or uncertain. At WQParts, we focus on one thing: supplying reliable aftermarket and replacement Komatsu parts that keep your equipment running in the real world — on jobsites, in quarries, and in demanding industrial environments.

Our catalog includes a broad selection of Komatsu parts for excavators, dozers, wheel loaders, and other heavy equipment. From wear components and seals to pins, bushings, bearings, filters, and hydraulic parts, every product we offer is selected with durability, fitment accuracy, and long-term performance in mind.

Built for Contractors, Fleet Managers, and Equipment Owners

We understand Komatsu equipment because we’ve spent decades around it. WQParts was built for professionals who rely on their machines every day and need Komatsu parts they can trust. Whether you’re maintaining a single excavator or managing a fleet across multiple locations, our goal is to help you minimize downtime and control operating costs without sacrificing quality.

Our aftermarket Komatsu parts are carefully sourced to meet or exceed OEM standards, offering a dependable alternative that makes sense for both short-term repairs and long-term maintenance strategies.
