The Ford 4F50N (AX4N) converter is prone to weak and/or broken spring clips, and a worn mating piston causes noise in this unit. Bending or replacing the spring clips is only a temporary fix. Sonnax clutch conversion plate FD-DA-18PB is a drop-in replacement that uses the existing damper, but converts the clutch from a 2- to a 1-friction ring piston. This eliminates the noise problem found in the OE units. FD-DA-18PB pistons can be identified by their "0" stamp.
Replaces noisy OE multi-plate clutch assembly, which is not available
Machined from a steel forging
Increased wall thickness for greater stiffness
