Great customer service
I didnt order enough parts i called and they work with me to update my order so i didnt have to pay a double shipping fee saving me some money -
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

My shipments are always handled expeditiously and delivered in record time to Uganda this is awesome from Propelparts.
