BD’s Xtruded Transmission Oil Coolers uses the same high efficiency Micro Extruded bar technology that is in our air-to-air Charge Air Coolers, providing 22% more cooling over other designs. The 200 Micro Extruded passages provide a large surface area to transfer heat for external air flow cooling while turbulent oil flow design promotes a more complete cooling. Large 5/8-inch ports prevents inlet/outlet restriction and furnace brazed rails have been tested to 300 psi of pressure. The thermostatically controlled 80-watt, 10-inch, 800 CFM electric fan offers ultimate automatic oil temperature control. This combination gives BD’s Xtruded Transmission Oil Cooler a rating of 33,930 BTU/HR and in excess of 30,000 GVW! Xtruded Transmission Oil Cooler packages are available to accommodate 5/16, 3/8, 1/2 and 5/8 transmission cooler lines and come complete with all fittings, clamps, hoses, hardware and a Build-It-Yourself galvanized bracket kit for quicker and cleaner installation – no wasting time fabricating brackets out of scrap metal. The pre-wired loomed harness with fuse and relay comes with OEM style sealed connectors to resist elements and give factory-like install look.
