Precision Engineering for Strength, Speed & Longevity
Built for power and reliability, this triple-disc billet torque converter features a billet stator for increased strength and durability under extreme loads. Its higher stall speed (approx. 2500 RPM) allows for better turbo response, making it ideal for performance setups requiring more RPM to hit boost faster. SunCoast's proprietary TIG-welded, furnace-brazed fins reinforce the converter for maximum longevity and efficiency. This unit also includes a forged billet cover, proprietary Raybestos clutches with trapezoid clutch teeth, and custom pump and turbine modifications—all designed and manufactured in-house by skilled American workers. Backed by a 3-year unlimited mileage warranty, this converter is built to dominate.
