Great pricing and fast shipping!
I'll admit that I was skeptical of propel parts, but they are an honest site and came through with the order. I was skeptical because I've never ordered heavy machinery parts, and didn't know who to trust. The parts that I ordered showed in stock, but after checking with their vendor, they only had half of the order in stock. I was notified the day after the order, and most of the parts arrived in a few days. There was one part that was not shipped putz but I was able to talk with who I assumed is the owner who rectified the situation and had the part overnighted to me.
I will say that communication speed could use a little work, but they will eventually get back with you.

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.
