With the same ½” copper tubing expanded into aluminium cooling fins and embossed turbulators as Derale’s larger transmission coolers, this cooler uses a slim design to enable frame mounting in limited space applications.

This kit comes with a complete transmission/trans cooler hardware kit to easily install onto vehicles with 5/16” transmission cooler lines. Perfect for light-duty use and occasional light towing.
