having undone the bag the seals and o rings came, I popped the small o rings on the bottom of the shock body, as you do, and having only recently rebuilt my Durango shocks, I put the large o rings at the bottom of the thread on the top of the body, thinking, like the durango, the shock cap screws down on the o ring. DDUUUUHHHHHH, no, I realised the large o rings go in the preload collars
Easy mistake to make. Moral of the story is, always look at the bloody instructions
