Hays Crankshaft Adapter Sleeves

Swap Engines and Automatic Transmissions Correctly

Hays Crankshaft Adapter Sleeves work great when adapting transmissions to engines they were not originally designed for operation. These sleeves will fit into the crankshaft flange and provide the correct dimensions for an automatic transmission torque converter snout, preventing the possibilities of harming the input shaft. Manufactured using only high-quality steel that is precisely CNC machined for a perfect fit.
