How to check Caterpillar part prices?

Enter a part number or machine model on the homepage to search. Batch search supports up to 500 part numbers per request with real-time pricing; registered members get exclusive discounted prices.

Do you supply OEM and aftermarket parts?

We supply both genuine Caterpillar parts and cost-effective OEM replacement parts. Choose genuine for original quality, or OEM parts for economy — typically 30%-50% cheaper with warranty included.

Do you ship worldwide?

Yes. WSTPARTS ships worldwide via DHL, FedEx, UPS and sea freight. Most in-stock orders ship within 24 hours.

Do your parts come with a warranty?

All parts come with quality assurance: genuine parts carry official warranty, OEM replacements carry industry-standard warranty, with return/exchange support for quality issues.

How to find a maintenance kit for my machine model?

Select your equipment type and model (e.g. 320D), then choose a 250/500/1000/2000/3000 hour service interval to get the full maintenance kit list — part numbers, names, quantities and prices for 92+ machine models.
