Key Features:

  • 8740 chrome moly steel construction rated at 180,000 psi tensile strength
  • 12-point design provides multiple engagement positions for easier installation in tight spaces
  • Black oxide finish for corrosion resistance and professional appearance

Ordered a Kirkey seat from them. They had the lowest price I could find and shipped that day. Ordered on Friday and received on Tuesday. It was well packed and perfect. I'd certainly do business with them again.<br>

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984

This was my first order with Autoplicity. Not only did they have the products I wanted at the lowest price, but they offered the best service and lightning fast shipping!!!

Great prices and fast shipping.
