Serpent is pleased to introduce these new adjusting nuts for setting the endplay of the 8.5mm pivot balls. Made from Nylon, they come in a set of 10 and replace the current aluminium nut with plastic insert which will not only makes assembly easier, it also reduces un-sprung weight. Reducing the parts used at this point also reduces side play so it makes for a more precise handling car and because the material used is self-lubricating the movement of the pivot ball will remain smooth throughout use.
