Installation of Hotchkis Rear Shocks

1

Raise the Truck

Raise the vehicle by using a drive-on alignment rack. Securely block the front
wheels of the vehicle.

2

Remove Old Shocks

Remove your old rear shocks by unfastening the top and bottom nuts & bolts. You may
discard the shocks and hardware.

3

Support the Trailing arms

Using the lifting jacks on your lift, support the rear trailing arms under the coil
springs. Jack the truck up until the rear wheels just begin to raise off the lift
surface.

Remove Stock Shock Mounts

Both the upper and lower shock mounts will be replaced. Using an air chisel, cut
off the rivet heads securing the upper mount to the rear frame. Completely remove
the rivets.

Next, remove the lower shock mounts by undoing the large u-bolts holding the rear
axle to the trailing arms. The lower mounts should be loose from the arms. You may
discard the upper and lower mounts.

Install Hotchkis Shock Mounts

Install the Hotchkis upper shock mounts as shown in the picture. Hardware is
provided for mounting to the existing rivet holes.
