18. Install the driver side up-
per a-arm drop bracket (90-
1155) into the stock a-arm
location points and onto the
frame. Reference ILLUSTRA-
TION 11 and note the following
a) Temporarily bolt (or hold
tightly) the new upper a-arm drop
bracket in place. Use an angle indi-
cator to insure the bracket sits paral-
lel (90 degrees) to the frame rail. If
it doesn’t, grind a little more where
the bump stop was cut off.
b) Once positioned, use the
upper a-arm drop bracket as a guide
to drill the 3 necessary 1/2” holes in
the frame.
c) Enlarge the two holes in
the outer face only of the frame to 3/4” so that the anti-crush sleeves (PN 90-2112 and PN 90-2113)
can be inserted into them. The holes on the backside are only large enough for the bolts to protrude,
not the sleeves. The sleeves are trapped between the inner frame wall and the drop bracket. The
sleeves prevent the frame from crushing when the bracket’s bolts are torqued to specifications during
final assembly.
NOTE: The center hole uses the longer sleeve and the front hole uses the shorter sleeve
NOTE: If you are installing a Pro-Comp shock hoop, install it at this time.
d) Install the upper a-arm drop
bracket into the original bracket slots using
the hardware provided as outlined in ILLUS-
TRATION 11.
⇒ REPEAT STEP 18 ON THE PAS-
SENGER SIDE.
19. Re-hang control arms. Start at the
driver side. Both sides install identically.
Raise the control arm assembly into position
with a floor jack. Install with 5/8” hardware
at the lower control arm attaching point with
the threads pointing in at each other as
shown in ILLUSTRATION 12. Now attach
