I am very unsatisfied, if I could give zero stars I would. I ordered two hub spindle nuts with keyways. once I received the product the keyways were not included. I contacted the phone number on the included business card and was sent out two keyways. One nut and keyway were correct, the second keyway was not working regardless of what the mechanic did to get it to work. I contacted TK back again and was told they were out of stock, but another one would be sent out as soon as they came in. A short time later I received an email asking me to send a photo. By this point, the mechanic had moved on to other jobs and one was not available. I did email specifics back to state why the keyway was not working. It has been over a week since and I have not heard back from this company. I won't use their services again. Complete waste of my time.
