Customer Reviews
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.
Online order.
I had a good experience this morning I placed an online order and everything went smoothly. The staff at propel parts has always been helpful in the past when I have been looking for harder to find parts or something that wasn’t listed online.
Our CSR for Dymax Inc., Deb, has been extremely helpful and consistently provides quick, accurate information regarding parts and inventory. When we encounter difficulties finalizing transactions through the internal website, she is able to promptly generate quotes and provide an external, secure method for payment. Her responsiveness and willingness to assist play a key role in supporting our team’s success.
