LS Swap Crankshaft Adapter Sleeve to TH400 Torque Stall Converter.

LS Crank Hub Adapter to TH400 Transmission conversions when using a TH400 converter

You use this LS adapter ring when swaping your 4L60E transmission to a TH400/TH350/Powerglide transmission. When using the TH400 type converter, the front pilot is not long enough to locate into the LS crankshaft spigot pilot hole. You use this converter extension adapter to fit into the LS crankshaft and locates the new torque converter. You may need to use spacers on the torque converter to push the converter back into the transmisison to engage the pump drive.
