The best supplier ever we mainly deal with most rare needed parts .. i highly recommend .. they are very very honest
-
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

I own old cat bulldozers D8k,D8H,D8N that required frequent repairs and servicing. it was erratic and practically cumbersome to keep them running without constant supply of reliable
and affordable spares in Uganda a third world country however,since I started dealing with propel parts US,my bulldozers have earned reliability and efficiency in providing high quality services to clients and making me a great dependable construction company in earth moving.
My shipments are always handled expeditiously and delivered in record time to Uganda this is awesome from Propelparts.
My business is booming by the clock for finding the best partner in Propelparts. -
Great customer service
Anthony was very professional and on top of what needed to be done to get my order verified and moving forward. -
Good Stuff.
We have had a couple shipping issues, but each time they made it right and we ended up getting what we need. Quality parts at half the price of OEM.
