Do Caterpillar parts come with a warranty?

Yes!

Your replacement tractor part may be provided by a Cat dealer or other source approved by Caterpillar. Bought an aftermarket part? These often come with warranties, too. Check with the site and manufacturer of the aftermarket part to find out. 

Should I buy aftermarket CAT parts? 

Aftermarket parts are a great way to save money and repair your machine on a budget. Whether you should buy them depends on your financial situation and your personal needs. Read more about the difference between original Caterpillar parts and aftermarket parts on our blog.
