1869 Custom Works BIG BORE SHOCK CAP EMULSION O_RING (8)

These optional emulsion o-rings are a great tuning option for the Custom Works MDX big bore shocks.  They are to be used in place of the stock shock cap bladders, fitting nicely into the machined groove in the inside of the shock caps.  It’s recommended to put a little shock oil on them for the first use, to ensure they glide smoothly against the top of the shock body when the cap is tightened down.
