So I've had works shocks since the late 90's and I was wanting front shocks with a compression setting. I found a great deal on Ebay for a set of works piggyback shocks that needed seals. I already have a couple sets of seals for them. So I took them apart and found that instead of a bladder they have a piston. My concern is how do I fill these things with oil. Do I have to set the piston depth on them? If a anyone has experience with the procedure I'd be grateful.
