It's closed cell foam, and it acts just as the bladder in the cap does. It compresses under heavy loading to take some of the force away, theoretically saving the seals.
I put integy piggybacks (just the piggybacks, traxxas shocks) on a set of traxxas ti-ni big bore shocks on my cybermaxx and they have been incredibly reliable shocks.
