The new 10-Speed XPL Pro-Loc Billet Bolt-Together 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 with the solid plate. Using this type of material increases manufacturing cost initially, as well as machine operation time, however 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 Lock-up technology with the following benefits:
The modular clutch basket assembly allows several clutch configurations allowing maximum tunability. This new modular design allows for unmatched time savings for servicing between rounds to accommodate changing track conditions.
Turbine clearance is redesigned to a fixed clearance, with a tighter tolerance reducing slip, allowing for a more efficient torque converter. This fixed turbine clearance also improves consistency and allows two thrust bearings to be used versus the factory phenolic thrust washers.
The sprag assembly is also replaced with our SunCoast Pro-Loc XL sprag that increases bearing roller surface by an additional 15%, improving reliability. Another great feature of these converters are their 3-pass design, allowing for individual control of the converter circuit. The converters are manufactured with provisions for studs; 10R80 has 4 or 8 studs and 10L90 has 6 studs. All of these are clamped together with (12) 12-point 5/16 bolts.
These new SunCoast Pro-Loc Torque Converters are proudly designed, engineered, and manufactured in-house in Fort Walton Beach, Florida, by American workers.
