This Ball Housing is appropriate for all SY Accumulator control valves. Earlier cars have housings that look a little different but this supersedes those as well.
The ball in the original ball housings get a flat spot on them from years of being pounded on by the bobbin piston but this these housings have a ball made from Silicon-Nitride Ceramic. They are orders of magnitude stronger than the original steel ball and are guaranted to never get a flat spot.
The housing is made from heat treated 4140 Chromoly.
These housings are included in every compete rebuild kit but are available separately here.
