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.
Great place for Cat parts!
Had some shipping difficulties, but everything was made right. Parts were perfect and an excellent price. Thanks!
He was a great help with ordering and refunding the sales tax,
I put 2 of the same orders in due to a web page error and shortly after I was contacted by Deb from customer service asking if I meant to place both orders. She was very helpful, the email was very well written and it genuinely made me feel better about the whole experience. She resolved the issue quickly and with there not being much of customer service these days I was very happy so see that is not the case everywhere!!!
