• Load-rated floor jack

• Safety stands x2

• Wheel Chocks

• Metric tool set

• Torque Wrench

•  Loctite threadlocker for all fasteners

This suspension system will enhance off road performance and increase 

ground clearance. 

Larger tires will increase vehicle roll center height.

 

The vehicle will handle and respond to driver steering and braking dif-

ferently from a stock factory equipped passenger car or truck. Extreme 

care must be used to prevent loss of control or vehicle rollover during 

abrupt maneuvers both on and off-road. Failure to operate this vehicle 

safely can result in vehicle damage, serious injury or death to the driver 

and passengers. 

Always wear your seat belt and reduce your speed, 

avoid sharp turns, inclines and abrupt maneuvers.

 Tread lightly, re-

spect nature and enjoy the Off-Road Experience! Help keep it available 

for future generations.

 

Thank You!
