FAQ

Are these genuine Caterpillar 365B parts?
We supply both genuine CAT parts with anti-counterfeit labels and OEM-equivalent alternatives built to the same specifications. All parts are fitment-verified for the 365B before dispatch and covered by a 12-month warranty.

How do I confirm the part number for my 365B?
Match the part number on your old part, or send us your machine serial number — WSTPARTS verifies fitment free of charge.
