Customer Reviews
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.
Excellent experience.
Mike has been very helpful. I am looking forward to keep doing business with them
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 service!
They are great !
I’ve been ordering parts from propel for about 3 years & counting. I live in Hawaii where we have a hard time getting parts especially for decent prices with fast shipping. I've been 100% satisfied with the company and the customer service and will continue to use them. I recommend propel to everyone here in Hawaii and we are all happy to have you guys. Thank you!!!
