WANTED TO THANK PROPEL PARTS FOR THEIR ATTENTION TO AN URGENT MATTER I HAD. THEY RESPONDED QUICKLY & RESOLVED IT. I ALSO WANTED TO MENYTION THAT OUR CUSTOMER'S ARE VERY HAPPY WITH THE PARTS EWE HAVE BEEN ORDERING FROM PROPEL. WE WILL DEFINITLEY CONTINUE TO DO BUSINESS. -
Great customer service.
Prompt , knowledgeable and friendly service. -
Great pricing and fast shipping!
I'll admit that I was skeptical of propel parts, but they are an honest site and came through with the order. I was skeptical because I've never ordered heavy machinery parts, and didn't know who to trust. The parts that I ordered showed in stock, but after checking with their vendor, they only had half of the order in stock. I was notified the day after the order, and most of the parts arrived in a few days. There was one part that was not shipped putz but I was able to talk with who I assumed is the owner who rectified the situation and had the part overnighted to me.
I will say that communication speed could use a little work, but they will eventually get back with you. -
Great service!

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.
