Sonnax stator cap FD-WA-24, along with heavy duty thrust bearing JA-N-13, replaces the OE impeller-side stator cap and wear plate in Ford E4OD, 4R100 and early 5R110W converters. Designed for higher stator thrust loads in high torque Ford diesel engines, the Sonnax stator cap supports the enclosed thrust bearing JA-N-13. Stator cap FD-WA-24 requires the standard non-wavy snap ring FD-SR-2.
