Customer Reviews
customer service and parts availability is fantastic
I almost want to cry ;( writing this review because I dont want people to find out about them and rather keep them in my pocket but they deserve it…
This company is great with Quality Products at amazing prices! Sometimes, their website is not the most accurate but is user friendly and if you got questions they will call back and are very prompt in responding via a call or text to verify inventory before placing an order.
I really appreciate and look forward to continuing to work with you all especially Anthony — he is amazing & the best!!!
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!!!
Customer service was great! There was a small problem with the part and they responded quickly and respectfully until was resolved! Highly recommended
Above and Beyond
Staff took care of issue that was nit created by them. Package was lost by UPS. Propel sent me another part Next Day Air to correct it.
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.
Great service affordable parts

Customer Service.
I recently had to cancel an order with Propel Parts, and I was thoroughly impressed by the prompt and efficient service I received. Steven handled my request with professionalism and speed, ensuring a hassle-free process. I've purchased parts from Propel Parts before and have never been disappointed. Their consistent reliability and excellent customer service keep me coming back.
