BEST for Heavy Equipment Parts.
Awesome quality products! Better customer service! Steven is always a pleasure to work with and very prompt in assisting me - thank you!
Everything fine, thank you. The only thing with which I had a problem in your Software, is that when I have more than 10 different items on the list, I can't scroll to the first ones. But besides that, I am very happy in going on with buying your parts.
Grateful I found this company!
I’m grateful I found this company! They answer the phone every time plus the parts are packaged very well!! Even the angriest mailman couldn’t damage your parts! lol The parts showed up as planned and for being aftermarket the quality seems to be good!! The warranty is the same as CAT. Thank you Daniel!!!
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.
Fast response and answers all my questions in a polite manner. Highly recommend.
Have been buying parts from them for years, and they have always delivered, both with parts and customer service.
Great company to deal with. Answered my questions with detail and shipped me the part in good time! I will be dealing with them more in the future!
Rapid response! Excellent service!
Very helpful. Every question or request I had was answered quickly. I didn't have a parts book for my excavator but that was no problem for them. If you need parts for your Cat, give them a shot.
Great customer service
Anthony was very professional and on top of what needed to be done to get my order verified and moving forward.
