19-row aluminum stacked-plate oil cooler with two nylon-braided 10AN hoses, rated 500 PSI, for engine oil, transmission or rear differential cooling.
A 19-row stacked-plate cooler moves a lot more heat than the thin tube-and-fin coolers most trucks leave the factory with, and it does it in a small footprint. The core measures 12.91 x 6.67 x 1.97 inches, is aluminum, and uses the common 330 mm bracket spacing so it bolts to standard oil cooler mounting brackets.
The kit comes with two CPE-lined, nylon-braided 10AN hoses (one 3.3 ft and one 3.9 ft, rated 500 PSI working pressure, -40 to 257 F), a spin-on filter sandwich adapter with an M20x1.5 center bolt, O-rings and a hose separator clamp. The sandwich adapter is for running it as an engine oil cooler; for transmission or differential use you plumb the 10AN lines into the cooler circuit with the correct adapter fittings for your lines.
Mount it in front of the radiator or behind the bumper opening where it sees steady airflow, check clearance before drilling, and pressure-test the connections before you drive it. Core test pressure is 116 PSI with a 232 PSI burst rating. Holding ATF temperature down while towing or in stop-and-go heat is the cheapest insurance a transmission can get.
