Sonnax offers heavy-duty forged front cover FD-CC-20R for the 11-1/4" Ford AODE, 4R70W torque converter. This cover is machined from a forging that allows the wall thickness to be increased where needed. The increased thickness between the friction ring surface and the mounting pads increases the stiffness of the front cover.
The friction surface on this cover is reaction (smooth) so that the friction ring is bonded to the piston instead of the cover. Bonding to the piston is easier and is preferred by most rebuilders. Bonding to this cover is still possible by machining a rough 90-120 RA finish on the clutch surface.
