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.
Awesome service prices and quality parts
Amazing service, emails answered very quickly with simple straight forward answers. Haven’t received the parts yet but ordering them was quick and easy.
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
Propel parts is a very reliable parts source for heavy equipment
Quick response,good quality parts,favourable prices and always deliver on time
