Cheapest priced ARP head studs on the internet. A++ I will definitely do more business with Autoplicity.

Placed an order with Adam on Monday, Nov 28th (#601). Very satisfied with Adam's technical knowledge and received my product on Nov 29th. The product is exactly as he represented and, because of this great customer service, I will place future orders.

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.

Found what I needed at an unbeatable price, easy purchase! No issues

The correct product that I ordered, and easy to find through there web site.thanks
