ok, I was wondering if anyone else is having these issues, I switched over on my original 5b from the 4mm shocks too the BAJA SS shock setup and now I'am going through more shock shafts then I have before cause the ends are pulling out..Is anyone else having these problems?i sent off an email to HPI but no reply back, @ 16.00 a pair it is starting to add up when the shaft is still good, but the end cannot be put back into the plastic ball ends...
