10L90 XPL PRO-LOC BILLET TORQUE CONVERTER 260MM

The new 10L90 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 plate 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 Lock-up technology with the following benefits:

• 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

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 this converter is the 3-pass design, allowing for individual control of the converter circuit. 

This converter is manufactured with provisions for 4 or 8 bolt holes to accommodate our SFI billet flexplate.All of this is clamped together with 16 12-point 5/16” bolts.

All SunCoast Torque Converters are proudly designed, engineered, and manufactured in-house in Fort Walton Beach, Florida, by American workers.
