Customer Reviews
Awesome and diligent support. Would definitely recommend
rapid response!
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!!!
Rapid response! Excellent service!
This is a great company to work with. Our sales associate Anthony quickly located the correct part and sent it out right away.
Great customer service!
Science I buy parts from propel parts I don’t have to spend too much down time always on time and good service
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
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.
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!!!
