Front end installation:

1. To begin installation, block the rear tires of the vehicle so that the vehicle is stable and can’t roll backwards. Safely lift the front of the vehicle and support the frame with a pair of jack stands. Place a jack stand on both the driver and the passenger side. Next, remove the front wheels and tires from both sides.

Repeat procedure on the passenger side. Special note: Make sure to keep the driver and passenger side coil springs separate from each other. We need to make sure that the driver side coil spring gets installed back into the vehicle on the driver side and the same with the passenger side.


6. Locate the new front coil spring spacers. Working on the driver side, install the new coil spring spacer over the stock bump stop cup. Repeat procedure on the passenger side.

Repeat procedure on the passenger side. Carefully raise up on both hydraulic floor jacks until the stock coil springs seat properly into the upper and lower locations.


8. Locate the stock lower shock mounting hardware. Working on the driver side, install the stock shock into the stock lower mounting location and secure using the stock
hardware. Make sure to use thread locker or locktite and torque to 65 ft lbs. Repeat procedure on the passenger side.

Special note: After the completion of the installation, Tuff Country EZ-Ride Suspension recommends taking the vehicle to an alignment shop and having a proper front end alignment performed.


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 responsibility 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 following these steps could cause brackets to come loose and cause serious damage to the suspension system and to the vehicle.


Tuff Country EZ-Ride Suspension packages (2) sets of instruction sheets with this box kit. (1) is for the installer and (1) is for the customer. The (1) for the customer has some post installation procedure literature and it is the installers responsibility to make sure that the customer receives a copy of the installation manual along with the literature.
