complete re-torque is done on all bolts associated with
this suspension system. It is the customers responsibil-
ity to make sure that a re-torque is performed on all
hardware associated with this suspension system after
the first 100 miles of installation. It is also the customers

ing these steps could cause brackets to come loose and
