Billet, Bolt-Together Converter; Rebuild Or Change Stall RPM at Home

The innovative TCI® 6L80/6L90 Bolt-Together Torque Converter features a triple-disc lock-up configuration and a bolt-together design that allows for easy disassembly. Removing the billet front provides access to the entire lock-up assembly, turbine, stator and bearings for servicing or restalling for future vehicle modifications. To further enhance strength, TCI® engineers included both a precision-ground billet impeller hub and billet front that are CNC-machined to reduce ballooning, while the billet turbine hub, billet lockup piston and billet clutch hub are pre-hardened.

Triple-Disc Lockup Clutch Handles Stock to BIG Horsepower

This patent-pending converter features a triple-disc lock-up clutch that utilizes woven carbon frictions that withstand the punishment of continuous slip lock-up control. The effective diameter of the clutch in conjunction with the triple-disc configuration provides for significantly higher torque capacity over the stock clutch. The lock-up clutch is attached to an industry-exclusive self regulating clutch hub which hydraulically modulates the apply pressure to allow for the smoothest engagement of any 6L80 converter on the market.
