These are known as the "ebay UCA". Google that term and I am sure you will find more. They also make a Titan version. I researched them quite a bit and was close to buying but found some TC arms used instead.

From what I discovered these are exact copy/clones of the TC arms. The uni ball and mounting hardware was the issue. The rubber bushing was said to hold up ok. The uniball would only last couple of 100 miles. The misalignment hardware was aluminum instead of steel. This info is from post and not first hand.
PRG made an upgrade kit for $150.

The cost of the arms + the upgrade kit will still be WAY cheaper than the TC arms.
