13. Adjust the lower control arms to a length of 22 7/8” from center of hole to center of hole and tighten the jam nut using
a 1 7/8” wrench. Install the adjustable heim end in the frame mount and the other end in the axle mount. Do not
tighten arms in the mounts at this time. See Photo 6. The bend on the lower control arm should be facing inward to
allow for the tires to achieve full lock to lock turning.
14. Remove the bolts securing the upper control arms to the axle using a 18mm wrench/socket. It will be necessary to
cut out the passenger side upper bolt as shown in Photo 7 to remove the control arm.
15. After the stock control arms have been removed assemble the bushings /sleeves in the upper control arms with the
heim joints. Adjust the arms to a length of 18 3/4” from center of hole to center of hole and tighten the jam nut using
a 1 1/8” wrench. Install in the heim joint in the upper mounts with supplied 10mm x 80mm bolt on the passenger side
frame and stock hardware on the driver side.
16. Install the opposite end on the axle with stock hardware. Do not fully tighten at this time. See Photo 8.
17. Loosen the stock brake line from the metal line on the frame rail shown in Photo 9 using a 12 mm line wrench. A
catch pan will be needed to catch the brake fluid.
18. Remove the line from the frame rail using a 10mm socket as shown in Photo 10. Remove the brake line from the
caliper and replace the brake line with the supplied stainless steel lines and brackets as shown in Photo 11.
Reattach at the caliper with new supplied crush washers, tighten line and install the spring clip.
19. Be sure the factory rubber isolators are in place and install the front coil springs. Insert the coil into the upper tower
first, followed by the lower seat. Be sure that the coils are rotated so that they seat properly. Raise the axle enough
to hold the coil springs in place.
