nerdling - The evo shocks are not the easiest shocks to build, but if you read the building procedure very closely they are very easy, the first time i built them i jumoed a couple of steps, just make sure you put the blabber on first, with the shaft a third in, pull out the shaft and it will pull the bladder in, put the top on, and then the al ring, screw it down and it will be perfect.
