LS Crank Adapter for TH350, TH400, 700R4, 4L60, PG

This adapter sleeve will adapt a GM LS engine to an older GM 2/3/4 speed automatic transmission torque converter. It centers the torque converter pilot into the LS crankshaft to allow the use of a TH400, TH350, Powerglide, 4L60, and 4L80 transmission that was not designed to be behind an LS platform. It is a premium steel component and will not wear like other products on the market made from aluminum.
