Oversized Bladder Caps
The oversized bladder cap is part of the factory shock kit to help disipate heat far more effectively than the stock item, it allows the shock to hold more nitrogen to transfer heat, also sticks out further into the airflow to radiate heat better. It looks pretty trick as well. Allows the shock to work longer without the fade suffered long into the race when the track is at its roughest. Works just as well with standard shocks.
