Pulled the tr***** on a Penske 8983 rear suspension unit. The only problem is there are no more piggyback shocks for the ZX6RJ. Had to settle for a unit with a remote reservoir. The only problem was, Penske gives you a pair of hose clamps to mount the reservoir...really a $900 shock with a pair of cheesy radiatror clamps? Anyway, Evo Technologies LLC makes a really neat aluminum reservoir clamp that you can bolt to the top shock bolt(or elsewhere) which solves the mounting problem. Now I have to buy a slightly longer Ti bolt. Can't wait to get the shock mounted and dialed in.
