The cradle bolts and all of the trailing and control arm bolts are torque to yield or a 1 time use fasteners per GM. We designed and released all of these parts before the service manual was available to the public, and we never went back and checked any of this info until now. We have sold hundreds of these kits as well as sets of arms and this is the first instance of a failure that we know of. Our own 2016 Camaro that we designed and tested all of these parts on has been taken apart and put back together multiple times and still uses the original bolts. We are changing our instructions to read that GM recommends that the bolts not be reused and will be including the GM part numbers(Listed below). We apologize for this inconvenience.
