Product was as described and was delivered promptly. I would order it again. This part was used in a stock race car build and I was very pleased with both the price and quality.

My last Wilwood master cylinder lasted 20 years in my off road race car and was still working. This was a good time to replace it and the old one will be an emergency spare. This is a great product.
