i think you r talking about this kit.the gpm steering kit is surpported by 2ballbearings so works more smoothly and fits tight.as my own experience,after a period of bashing the stock steering set is bound to be loose which leads to unprecise control in steering.
maybe i spelled incorrectly~~inprecise or unprecise? who cares
