This is our strongest Torque converter for the 4L80E transmission and is available in stall speeds up to 4500rpm and applications up to 900HP.
This converter features a billet 1 piece front cover with pilots for GM V-8 engines as well as LS1 style engines. We use a special clutch design that not only has a greater clutch surface area than any other single piston 4L80E converter but will also work with GM ec3 programming. Other features include, full furnace brazing of all internal fins on both the cover and stator, heavy duty sprag and race, full Torrington bearings throughout, hardened hub, hardened turbine spline, anti ballooning plate, fully computer balanced. If you need a high stall converter for the 4L80E then this one can take the punishment!
