Safety Warning:
Suspension systems or components that enhance the off-road performance of your
vehicle may cause it to handle differently, on and off-road, than it did from the
factory. Care must be taken to prevent loss of control or vehicle rollover during
sudden maneuvers. Failure to drive the vehicle safely may result in serious injury
or death to driver and passengers. We recommend you always wear your seatbelt,
drive safely and avoid quick turns and other sudden maneuvers. Constant
maintenance is required to keep your vehicle safe. Thoroughly inspect your vehicle
before and after every off-road use.

PRE INSTALLATION NOTE:
Control arm bushings are pre-lubed during initial assembly at Rubicon

are available through Rubicon Express (RE3771 & RE3772) if needed for
tightening of the joints.
