Suncoast Converters 13 TH400 Diesel / Tow Converter COA-20004

The SunCoast Pro-Loc TH400 Torque Converter is manufactured from a solid piece of 7075 T6 billet aluminum plate versus round bar like so many other manufacturers. We take this extra step in manufacturing from solid billet plates due to the superior heat-treating characteristics. When using round bar, we see the tempering is not as solid in the center as solid plate. While using this type of material increases manufacturing cost, it is a necessary step when considering the high inertia and its effects on ballooning the converter. The SunCoast Pro-Loc Bolt-Together converter also includes our patent-pending Zero-Drag Lockup technology which: - Allows constant oil flow across the clutch surfaces extracting heat and improving lifespan - Less parasitic loss, resulting in more power to the ground - Quicker throttle response - Faster spooling of aftermarket larger turbochargers.
