Tuff Country EZ-Ride Suspension recommends that a
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
responsibility to do a complete re-torque after every
3000 miles or after every off road use. Neglect of follow-
ing these steps could cause brackets to come loose and
cause serious damage to the suspension system and to
the vehicle.
