Customer Reviews
Propel parts is a good Cat vendor that provides a top notch service to customers from ordering to delivery. Their after sales service is really impressive.
When I had questions, they were answered quickly and kindly.
Thank you!!
Will definitely use regularly!
Shipped the exact product we were looking for. Prompt Customer Service. Seamless cross-border shipping
Great Customer Service!
Had some difficulties with the website. Contacted customer service. Once I communicated the issues I was having Steven worked through getting my order processed and making sure I got my receipt and all issues resolved. Perfect!
I would give 5 stars but my first time ordering from here and using aftermarket parts. The price is reasonable comparing to original Cat parts and the customer support is great and hoping to do more business with them

Keep up the great work!
