7. Install axle support brackets, 94051040, drivers side, and 94061040 passenger side as shown and bolt them to
the axle pivot brackets using the supplied 7/16” x 1 ¼” bolts, washers and nuts. Connect the two axle pivot
brackets together using the 7/16” hardware and tighten to 70 ft. lbs. Position the axles into the drop brackets
and install the axle bolts. Torque to 150 ft/lbs.
8. Position the Rough Country leaf springs with the long end towards the rear of the vehicle. Bolt up the rear eye;
torque to 120-150 ft/lbs. Because of the spring arch, it may not seem long enough to bolt up to the front
shackle. If so, place some type of spacer and pry bar between the springs attaching point at the shackle and
the spring eye. Jack up the axle ands as pressure is applied to the spring it will become longer and will enable
the spring to be bolted into place. This procedure can be very dangerous, use caution when loading the spring.
Another alternative is to slot the frame to allow for the shackle to move rearward.
9. Before securing the springs to the axles, be sure the center pin on the spring seats properly on the axles. Install
the new u-bolts and torque to 130 ft/lbs.
10. Install the new Heckethorn shock absorbers and install the tires and wheels.
11. Remove the jack stands and lower the vehicle to the ground.

pitman arm. Torque the nut to 55-75 ft/lbs. and install the cotter pin.
