The new Motion Raceworks Billet Water Pump Adapter allows you to adapt an LS water pump to an AN thread.  This makes easy work of building radiator hoses on your swap or race vehicle.  

CNC machined IN HOUSE at Motion Raceworks, this Made in the USA piece is very nice.  Made to utilize the factory style standard 2.12" 04-08 LS2 and LS7 thermostat (Part Numbers below). This housing is made with both narrow and wide pattern to adapt to both truck and car style pumps.  

This housing allows you to adapt to 12, 16, or 20AN hoses.  However, we have not seen noticeable gains in cooling moving on sizes above 16AN. This only drives fitting cost up.
