I guess too much pack(force) under compression.

I message VRP and he told me they need to be two washers for top and bottom !!
Interesting they told you this, yet still only offer one washer per piston.
I suppose the bottom would have the most force put against it during forced compression, so maybe they figure the top side is ok without it?
Appreciate the info none the less. I would have ended up breaking mine if I hadn't heard about it from your post.
