This kit eliminates the problematic factory oil cooler lines/fitting connections and replaces them with braided CPE lines and AN fittings. 

This kit fits all GMT400 oil filter housings, and all GMT400 radiators equipped with M20x1.5 fitting connection threads - please examine photos below to determine if your oil cooler uses the same fitting style. 

This kit includes our custom M20x1.5 to 6AN radial groove o-ring fitting. This fitting is designed specifically for GMT400 radiators with M20x1.5 threads to adapt to 6AN. It uses the same radial groove sealing method as the OEM fitting and many of the fitting kits that come with new replacement radiators. 

If you ordered the Gen 1 kit with the previous style radiator fittings (with crush washer), you can get our new fittings here: M20 x 1.5 to 6AN Oil Cooler Fitting – Kloc Fabrication

Above photos show the details of our KFB-0326-001 fitting that is included with the kit. The oil cooler shown is removed from the GMT400 radiator. The brass fitting is what is often included with replacement radiators or used with the OEM oil cooler lines. Please examine the fitting ports closely to determine if yours are the same. These are M20x1.5 thread, and use an o-ring to seal on the inside flat of the port.
