(4) Remove centering pin and install one spacer per pin.
Reinstall pin (Inset A). If nut does not have full thread
contact, replace centering pin. Set L-bracket on leaf
with the pin through the slot. Make sure that the post
part of the “L” is facing forward.
(5) Drop the axle back down, and reinstalled U-bolts.
Slightly tighten U-bolts so that L-bracket can be adjusted
later.
(6) Install lower bracket on other side in same manner.
b. Non Flip Axle Kits:
(1) Set the preassembled bracket/tool unit on the leaf spring
forward of the axle.
(2) With the hook end of the lower bracket placed over the
edge of the upper spring retaining plate, secure the lower
bracket to the leaf spring with the provided U-bolt, flat
washers, and lock nuts. Torque to 16 ft–lbs.
NOTE: On some conversions, it may be necessary to
trim the seat bolts protruding down from the floorboard
in the area of the assembly mounts.
7. The upper bracket can be mounted right side up or upside down
to attain correct design height (Figure 1).
NOTE: If used, adjust L-bracket so upper bracket clears the
notch, bolts, or anything else that may interfere with the upper
bracket installation.
8. Using the slot in the lower bracket, push the upper bracket
against the frame rail. Use the nuts on the threaded portion of
the installation tool to adjust the upper bracket so that the flanges
of the upper bracket are flat against the frame rail and all four
mounting holes are on the flat middle section of the frame rail.
The mounting holes must be at least
3
/
4
" from the rounded edges
of the frame rail. It is also necessary to allow at least 1

above the upper bracket for air fitting clearance. The brackets
can be mounted anywhere within the threaded range of the
installation tool (Figure 1).
9. Using the upper bracket as a template, follow the specific
directions below for passenger and driver sides.
a. Passenger Side:
(1) Centerpunch and drill a
3
/
8
" hole through the forward
upper mounting hole. Insert the
3
/

" x 4" frame bolt/flat
washers/locknut and leave loose. Note: On exhaust
side of vehicle it may be necessary to move or trim stock
heat shield to gain access to mounting bolts.
(2) Next centerpunch and drill through the rear upper
mounting hole. Do not insert the bolt.
(3) The installation tool can now be removed by removing
the upper nylon nut, loosening and removing the tool
from the bottom bolt (leave in place), and slightly rotating
the upper bracket to give you enough room to completely
remove the tool.
